It will not boot to bios. I read on this forum where Jason Kovacs had the same issue with a HP. I will be ordering a new motherboard as I noticed the Model numbers are different yet most of the components are the same. Lee Allen wrote 'The model that was used as a replacement was the ASUS P5KPL-CM.

Unfortunately, that specific model is not longer available. There is an updated version, the ASUS P5KPL-AM that features an upgraded LAN port and is Windows 7 ready.' I do hope this is how to start my own thread as I am new here and not familar with the format used here. If this is posted improperly maybe a Moderator could help me out and fix it.

Thank you for all the great help! Good job Larry, it's not that hard and you're off to a great start. We all started out like you at one time or another.

The ASUS P5KPL-AM EPU LGA 775 Intel G31 Micro ATX Intel Motherboard came in. I carefully disassembled everything.

I installed the new Motherboard using the existing Ram 2 1Gig (PC2-5300 Mb/s)and the Pentium Dual Core E2180 CPU. I also placed all the rubber supports from the Foxconn board in the same spot on the new Asus Board avoiding putting them on any circuit runs. I was surprised that the board came only with a ATA cable. Well on to my problem. This board will not do anything when I try to power it up.

The fans will not spin at all. Is it possible I have received a DOA board?

Any suggestions are welcomed. I would like to add that I do not know if the Ram or CPU are good as they are from the old computer. I know the SATA HDD is good and also that the PSU is good. Maybe I am overlooking something small but I have gone over the steps and can not figure out what I could have done wrong.

I even used a wrist ground strap just to be on the safe side. The only part of this computer that is not connected is the Media bay and it requires a 1394 port and this Motherboard does not have one. Thanks to all that are assisting in my quest. OK Larry, sorry to take so long getting back. First, unplug the power supple from the power soured, remove all add-on cards (if any) and both sticks of memory. Also, remove any hard drive connectors.

Second, pull out the power connector (the 24 pin EATXPWR) and the 12 Volt connector (ATX12V) near the PS2 connectors and the parallel and serial ports on the back of the motherboard. Third, reinsert these connectors firmly and ensure they are locked in. Fourth, insert one memory chip in the DIMMA1 slot. Fifth, reconnect the power supply to the power source and start the machine. Look for the fans to start running. If not, turn it off and disconnect the power again. Remove the memory stick from the A1 slot and put it in the B1 slot.

Repeat this with each stick of memory until the fans work or nothing happens. Make sure the green LED marked SBPWR lights up when the power is on. This will help determine if you have a bad memory stick or a bad motherboard. Since both memory sticks worked before, the motherboard may be suspect.

Get back to us with your results. Warm regards, The information transmitted is intended solely for the individual(s) or entity to whom it is addressed and may contain confidential and/or privileged material.

Is it possible I have received a DOA board? Any suggestions are welcomed. If the green LED doesn't light up either the motherboard or power supply are not working. You are sure you have both power connections hooked up. Sometimes people forger the 12V 4 pin connector. I just hope we aren't getting into the proverbial 'upgrade cascade.'

' (LOL) The CPU can be a suspect at this point as well. Are you getting any audible codes when you attempt to power up? I think we have either a DOA motherboard (it does happen) or a faulty power supply.

The power supply could have been damaged connecting it to a bad motherboard.

I did as you instructed. Nothing powered up. No light on Mother Board. No Fans I removed the Memory from A1 and exchanged with the other stick. I tried the memory as single first in A1 neither stick helped. I removed the memory stick from the B1 slot and put it in the A1 slot. (2 sticks) All PSU connectors are seated.

I did that part twice. The green LED marked SBPWR won't light up when the power is on. Thanks again for your help Lee! I assure you that all the power connections were firmly seated. I am going to RMA the Motherboard as I suspect I received a returned board as a new one. When the Board came it had no Manual no I/O Plate and no SATA cables. I downloaded the Asus manual online and it said the Mother should contain these items.

I do have a new 750 watt power supply I can try on this motherboard but am leary to do this at this point. I have a confirmed working 650 watt Corsair PSU I can use also. The last computer I built ran XP Pro for 5 years so my skill level isn't a complete newbie.

I have built a few machines over the last 15 years. I have also limited work with circuit boards and component replacement. I am stumped with this computer. The only time I have ever failed to post Bios it was a power supply.

I like to start a build with all new components and am more comfortable that way. I will swap out the new 585 with the 650 watt and report what happens. I am also building a new AMD Quad core for myself I will be posting about later good or bad. Lee I am very grateful for your assistance and the opportunity to learn from your experience. Thanks again for all your help. Lee I tried the 650 PSU and the same result.

So I pulled the motherboard out of the case to get it ready for the RMA. I figured I would try it out of the case so I put it on my non Conductive mat and hooked up the 585 watt PSU and the Input from the tower. Much to my surprise.

The Mother board led lit up and the CPU fan started spinning like it was going to work then the CPU fan increased in RPM then it shut off. The LED on the tower to start the machine goes out but the light on the motherboard stays on. I went back to the first steps you outlined and did the memory swap in all configurations possible with no change. I then changed to the 650 watt power supply and had the same results. I hope this gives you some more information that will be helpful to you assisting me. Once again I thank you for your time Lee!

Sorry about this Lee but I have another update. I took some plastic stand offs and put then under the mother board thinking the CPU fan might not be reading correctly.

Well after doing this the baord fires up and stays on. I also connected the sata drive to it and it still runs with the drive attached.

I went and inspected the Foxconn MB and it seems to have a coating for liquid tape applied to the underside of it. Like it was applied after the board soldering took place. My next step will be to hook up a monitor and the keyboard and mouse and try to boot it unless you have a reason I should not. I think we are making some progress here. Let me know if I can supply anything you might need.

I can take and post pictures for you if that helps. Thank You very much for staying in here and helping me! Great news Larry. I tried to send you the link to a firewire card, but somehow it got rejected by the server thinking it was a system command. The text I tried to send was: Remove the space between the 2 and the E.

Here's the link surrounded by parentheses. If there are any spaces, the link will appear broken. Just remove the spaces and it will work. I don't know why, but this site puts spaces and carriage returns into the links because of their length.

(Or you can use It sounds like you are making great progress and I encourage you to continue to attach one thing at a time. Those standoffs you mention are an older technology and most are steel to make a good ground to the case.

It is important that they have a good contact. Also make sure you connect all the fans to the correct posts on the motherboard because the ASUS boards have thorough monitoring built in. Let me know what happens next.

Warm regards. I tried to boot the unit off the bench and something still is not right. Now the fans run about 15 seconds start to ramp up in speed then the light goes off on the tower and the motherboard led stays on.

I tried both power supplies and then pulled out my new 750 watt PSU and the same thing happened. I am now thinking that it was more than a motherboard failure on the original computer and the CPU might be damaged also. Your thoughts?

What would you suggest as a replacement CPU? I was able to see the firewire card using tinyurl. Thank You very much for your assistance Lee! Larry, yes, go ahead and connect monitor and keyboard and see if you can get it to work outside the case. I'm sorry if I have sounded a little too elementary, but I have to be able to give direction to all levels of expertise here. It's refreshing when someone of your experience comes along and then I can dispense with some of the really basic stuff. It's also a good sign that the board is working outside the case.

We might be able to easily take care of that problem. I'm eagerly waiting to hear what you accomplish. Warm regards, The information transmitted is intended solely for the individual(s) or entity to whom it is addressed and may contain confidential and/or privileged material.

The plastic stand offs have it elevated from my non conductive mat. I am thinking that somehow the board shorts out when mounted in the case. Everything I am doing is off the work bench not inside the tower, I want to hook up a monitor and keyboard and try to boot it from the work bench. Is this a safe thing to do?

Lee I think we are out pacing the moderators. I am very grateful for your help. I learn everyday and I am glad there are still people willing to teach as it is not an easy thing to do. My final results are that even with the new Mother board it will still not reach Bios. It will not send a video signal to the monitor.

I have used AMD and never really messed with Intel CPU's. I think the next logical step is to get a new CPU. I think it may have suffered damage as well as the old Foxconn board.

I was looking at codeas a CPU or maybe codeI am not really too keen about the Celeron. I await your reply. Thank Again for all your help! LOL, you're right about that, the poor moderators have their hands full. Before buying a new processor, have you reset the HSF with Arctic Silver or something like that?

If you go for the new processor I would advise: It's an Intel Core2 Duo E7500 Wolfdale 2.93GHz 3MB L2 Cache LGA 775 65W Dual-Core Processor and should provide several good years of service. You could also upgrade at a later date to a full 4 Gig of memory and with W7 64 bit use it all.

I will do it again just to be sure and it never hurts to double check. I would love to get that CPU but with my recent new build it's out of the budget for what this machine needs to do. Thats why I was looking at the other CPU's that were cheaper. I made a mistake and ordered some parts from Tiger and it didn't turn out well for me. I won't go into it as it would probably be considered bashing.

This computer really is used mostly for e-mail and internet browsing. It doesn't really do a lot of work.

I would post my newest build but I really don't know the proper section to post it in. I am still trying to get used to this format. Once again Lee I thank you for all your time spent helping me with this. I here you Larry. The ironic thing I am finding is that Internet browsing is now becoming the most CPU and memory intensive processing performed. The times that my CPU utilization spikes is when I'm using my browser.

Now, I have a bad habit of keeping several windows open, but it still is the heaviest work I do and that includes Photoshop, video authoring, and CAD. PS: my experience with TD has been spotty as well. I have just upgraded my wife's computer and I am real jealous. I'm just going to have to do the same to my desktop.

I don't have the money yet to start my next new unit. What I have found is nothing compares to a powerful processor with lots of memory and a 64 bit OS.

I have had great results using AMD in the past so I deceided to stick with them and I also have a strong affection for ASUS motherboards. Mainboard: Asus M3N72-D Chipset: nVidia nForce 740a SLI Processor: AMD Phenom X4 9850 Black Edition @ 2500 MHz Physical Memory: 4096 MB (2 x 2048 DDR2-SDRAM ) Video Card: NVIDIA GeForce 9500 GT Hard Disk: WDC (1000 GB) DVD-Rom Drive: ATAPI iHAS224 A ATA Device DVD-Rom Drive: ATAPI iHAS224 A ATA Device Monitor Type: Envision H19W - 19 inches Network Card: MCP77 Ethernet Operating System: Windows 7 Ultimate Professional 6.01.7600 (x64) DirectX: Version 11.00 Windows Performance Index: 4.4 on 7.9 This is everything stock without any tweaking yet. I know that this Quad can do a bit better. The case is a RAIDMAX SMILODON ATX-612WBP Black 1.0mm SECC Steel ATX Mid Tower Foldout MB Computer Case that came with a 500 watt PSU. I pulled the 500 watt and installed a 750 watt PSU. The 750 Watt PSU were on shell shocker so cheap I had to purchase 2 of them.

I upgraded the stock fans and added a few more fans for better cooling. Powered by a Belkin's Enterprise Dual-Form Factor 8 Battery Backup 1500V Surge Outlets with USB, RJ-11, and RJ-45 Protection. Thats the creature that has be not wanting to invest much in the HP as I really would like another 4 Gigs of RAM.

Thanks again for all your help! Update, I found another processor exactly the same as you have at: When reseating the HSF, make sure you clean any of the previous paste from the HSF and the processor. Then use the paste sparingly since it is a conductor and will short out the processor. But then, you know this. Your symptoms described regarding the HSF starting, then speeding up, and then the system shutting down sounds like a temp problem.

I'm not certain, but that's my initial thought based on what you are experiencing. Warm regards. Good morning Larry, Since were sharing specs, my wife's upgrade was a complete gutting (original parts were my first build in 2003 based on an AMD Athlon XP processor. That must be a very sweet system. Your future build looks even better! I also don't game. With the internet service in my current area I could get by with almost any computer as my DL speed is 3.0mb but drops as low as 33k and I have a 425 meg a day cap.

That is the premium package offered. We are in the country and Hughes Internet service is it besides dial - up. I miss the 30mb30mb fiber they had in Chicago. That was really nice. We are wired and wireless here so the laptop can function outside at the picnic table.

The wireless router has DD-WRT stuffed into a old linksys with the output jacked way up and I added some heat sinks and a fan to help cool it. After sleeping on your suggestion about reseating the HSF I realized I don't know how old the Artic Silver I used was and it did not seem to flow properly when I applied it. I seem to remember it being more creamy than what I applied. I am going to pick up a new tube and give it another go over this weekend. Thanks for finding that replacement CPU for me I book marked it. I have also been thinking about the other chip you suggested. After going over the specs you really do get a lot more for the few extra dollars.

Some days I have that Old Timers set in and neglect to pay complete attention to the areas I should. Thanks again for all your help! I am grateful for the information you so willingly share.

I will let you know what happens when I do the HSF with the new compound. Take care Larry. I had hoped to have an update today but after visiting the computer shop a few towns away I couldn't bring myself to pay the 12.99 he wanted for a single application unit of Thermal compound (0.5g0. I am looking at a longer delay as I will have to order it and wait on delivery. Just for grins I asked the price for a OEM Fan and was told the current rate was 39,95.

My current HSF is a 4 pin and the HSF he tried to say was OEM was a 3 pin. Maybe you could shed some light on this for me.

This is the first time I have been to a computer supply store where it was more like a car dealership. Thanks again for all the help I have received since my arrival. Can you tell me if this CPU will work for me with my current items? Here is a link. (It is a Intel Pentium Dual-Core E6500 Wolfdale 2.93GHz 2MB L2 Cache LGA 775 65W Dual-Core Processor. I know it is not as nice as the 3MB L2 Cache you suggested Lee but right now the cheaper the better. The exact replacement one you sent me would work out to be more than this item as it doesn't include the HSF.

Since I am not sure that this will work for me I will await a reply. Thank you in advance for your time and patience. I know what you mean about the local computer shops.

My father used to work with one here in SC, but the old man got greedy. The son understood what customer service was all about, but had to disobey the old man to help my father. It was then that I started to do all of his work. Regarding the HSF connectors, I think you are correct. The HSF has an additional pin to facilitate the MB monitoring.

There are usually connectors to hook up a chassis fan which is three pins. In this day and age there are many 'experts' out there willing to help, but it is very difficult to find the real knowledge holders. In the meantime, it might be a good idea to look for some small rubber washers to place on top of the motherboard connectors in your case to raise it up sufficiently to mitigate any potential shorting to the case.

Some Superglue or similar could fix them to the standoffs so you can insert the screws without them being moved out of place. That or using a sheet of plastic between the board and the case to create an insulating buffer. The only downside I see with that is over time the heat will soften the plastic and sharp points will penetrate the plastic. We'll need to give this some serious thought. Anything that changes the plane of the motherboard could prevent add on cards from seating properly and aligning with the openings in the back of the case.

It appears the one you suggest will work fine for you and it does feature the upgraded FSB. Keep up the good work!

I am ordering the CPU and hope to be back with an update of a running computer here in the next few days. I also went ahead and ordered some new Arctic Silver at a reasonable price. I have the standoffs that were on the Foxconn board that I tried on the Asus Board with bad results. But I seem to remember using a spray on coating on the back of a Motherboard inside a Kawaguchi Injection molding Machine a few years back.

It was used to prevent any damage from moisture and also had a high temp limit along with high insulating properties. First the board was sprayed with a cleaner that took off anything the soldering process left behind and then the coating was applied. Old Timers is setting in at the moment but I will remember the name after I search the net for awhile. I think we purchased it from ECG or ECC or ECE Electronic supply or something like that. I have a couple ideas once the unit is running out of the case and I think it will be easier to figure out a final solution to the problem when i don't have to worry about the components. I have a wide variety of tools compiled over my lifetime at my disposal.

When we get it up and 100% functional I will take some photo's of the Mods that were needed and might even compile it into a PDF file for future reference. I know that I won't quit until it is 100% functional and I am very grateful for all your help! I started thing about this issue more in depth and I also began to think if this becomes a solution to this problem it must not violate any warranties and be an inexpensive easy to do for anyone to preform.

I think the answer is to mod the tower as it is out of warranty instead of doing anything to the new Mother board. I have an idea and am going to implement it today. I will update you as soon as I prove or disprove my idea. Thanks for all your help because without it the HP would stay dead with no real answers on how to properly repair it.

Sounds like a plan. Awaiting your posts.

I am confident that we won't have anymore issues with the case. I researched quite a few products and found one that is inexpensive and readily available from Harbor Freight. Black Liquid Spray Tape Spray-on insulation coating permanently seals out moisture, salt, and other elements Flexible rubber formula won't crack, peel or harden like vinyl tapeInsulates for electrical shock and vibration Won't unravel like tape Convenient, easy-to-use application 6 oz.

ITEM 65200-ZZZ $5.99 CLEAR LIQUID TAPE SPRAY ITEM 97066-ZZZ $5.99 Can be picked up at your local store or ordered from I applied 1 coating and let dry for 24 hours and began to test for conductivity with my ohm meter. Everything checked out. Next I installed the mounting screws to the mounting holes and they have conductivity. I used heat to increase the cure before applying another coat. So far so good.

I will go more in depth after full cure is reached. By tomorrow the rest of the parts should arrive and enable me to assemble and test the unit. I also found some products priced as high as $29,99 and the Dielectric Strength (Volts/Mill) were the same along with a few other specs that matter. Thanks again Lee! I think we are going to have a permanent fix for this model HP after all! Great ideas Larry. I've found myself relying on hot melt glue for similar situations.

Mainly because I have it and it works. I'm looking forward to a successful resolution to this interesting problem. I retrofitted an ATX motherboard into an old AT case and I was surprised how easy it was after finding someone who could mod the back of the case to allow the ATX connections to work. It's not pretty, but who looks at the back of the case up against the wall? Besides, it enhances air flow (LOL).

I am confident that we won't have anymore issues with the case. I researched quite a few products and found one that is inexpensive and readily available from Harbor Freight.

Black Liquid Spray Tape Spray-on insulation coating permanently seals out moisture, salt, and other elements Flexible rubber formula won't crack, peel or harden like vinyl tapeInsulates for electrical shock and vibration Won't unravel like tape Convenient, easy-to-use application 6 oz. ITEM 65200-ZZZ $5.99 CLEAR LIQUID TAPE SPRAY ITEM 97066-ZZZ $5.99 Can be picked up at your local store or ordered from I applied 1 coating and let dry for 24 hours and began to test for conductivity with my ohm meter. Everything checked out. Next I installed the mounting screws to the mounting holes and they have conductivity.

I used heat to increase the cure before applying another coat. So far so good. I will go more in depth after full cure is reached. By tomorrow the rest of the parts should arrive and enable me to assemble and test the unit. I also found some products priced as high as $29,99 and the Dielectric Strength (Volts/Mill) were the same along with a few other specs that matter. Thanks again Lee!

We have solved the issue. When the foxconn board expired the CPU went with it. I neglected to mention that the Mother Board supports in this case are just stamped sheet metal and stand up as a bump. That is where the problem begins as their size is huge in comparison to a regular stand-off. The pins on the Asus PK5KPL-AM EPU Motherboard that short out are the CLRTC and also one of the DIMM sockets.

The application of the spray insulator did it's job and the unit has been up and running for 24 hours without any problems. I think any board other than the original Foxconn will cause problems in this HP case. The OEM Vista was all messed up from when the unit died so I reformatted the HDD and did a fresh install of Win 7 32 bit.

It is a bit weak in the graphics but I'm using the on board video and it rates 3.2 but the overall rating in Win 7 32 bit is 7.9 so I'm happy with the overall results. The total bill was less than the $200.00 limit and I think it will last for a few years. I really do not like the HSF at all. It was a HUGE pain to make sure it was properly seated and locked in. I would wis it was held down with screws I would feel so much safer.

I think over the next year I will upgrade the ram and add a video card along with the 1394 add on as well. I have enjoyed your help and input on this repair and would like you to know without your help I would have never pulled this off. I also need to thank Joel for going out of his way to help me with my account problems! There sure is a great bunch of guys here!

Thanks again to all. Larry (I will update over the next year to confirm the unit is still running properly.).

That's great Larry, good news is always welcome. I'm glad you were able to rectify the electrical problem, especially isolating what was wrong so you could fabricate a resolution. Great thinking out of the box. Personally, I have found the LGA 775 HSFs very easy to work with. Lining everything up is a cakewalk compared to the old Socket 462 (A) CPUs. The fact you don't have to torque down the HSF is a plus in my book.

Good luck with this guy and I hope you share your obvious competencies with all of us here at Toolbox. Warm regards. It may be that I was a virgin when it comes to that type of HSF that caused me trouble. I am an AMD freak that is use to straps and screws. I must admit that after this rebuild I am now thinking about a new INTEL based Build for my next project. For the few dollars that were invested into this unit it really screams and if I would have went with the suggested CPU i suspect I would see even better results. I am more than satisfied with the current rebuild.

Nothing like a hands on to increase ones experience and reopen the mind to new things. I have a new found respect for the INTEL CPU. I plan to hang about ittoolbox for quite a while and keep learning new things here. I will assist when I can also. I have re-branded the computer from HP to ittoolcom Model 0001 and it is still running very cool and smooth despite todays high ambient temp and humidity. My new build is starting to act up so I will open a new thread on that unit soon.

I will update this thread every so often on the status of the rebuild, Thanks again!
