| 471670 | 2006-07-18 03:49:00 | Hello, I built my PC like a week ago, and it was working perfect no problems. I disassembled it to reseat the HSF, and it worked great. This last time I did some mods to my HSF, I put a new fan and some heatsinks on my big typhoon, and put the computer back together and it wont start. I have everything but the power cable disconnected. I reset the CMOS, and I have found that with the ATX 4 pin power plug in, the system will kick and the fans will spin for a split second, then everything will stop. It also makes a funny noise when this happens. When I remove the ATX plug the fans will start spinning and everything seems normal. I have an 600W OCZ power supply, Asus p5wd2 premuim mobo, 2gigs ddr2 667 OCZ ram, D 805.... Can anyone help me pinpoint what the problem might be??? I want to get this running again tonight, but everytime I plug in the 4 pin ATX plug it just wont happen. I hope its not a faulty PSU lead I dont want to spend weeks without a computer waiting on RMA. The power supply and the fans all run normally when the ATX plug isnt plugged in. |

| 471671 | 2006-07-18 03:59:00 | That looks as if you have a short circuit. The cable's probably OK: it's carrying enough current to shut the power supply down. ) | Graham L (2) | ||
| 471672 | 2006-07-18 04:07:00 | So, its my motherboard? | 1Bad (10764) | ||
| 471673 | 2006-07-18 04:12:00 | If it all worked before, it's most likely in the way you put it back together. You have probably got a point on the motherboard carrying 12 volts (or some other supply --- what is in that 4 wire lead?) firmly screwed to the case. This is not a Good Idea, as you have found. It has probably not killed anything. |

| 471674 | 2006-07-18 04:59:00 | Have you changed the HSF, is one of the bolts which fix it to the mobo, touching the case on the underside, shorting the board? | SolMiester (139) | ||

This last time I did some mods to my HSF, I put a new fan and some heatsinks on my big typhoon, and put the computer back together and it wont start. Like a week ago? Does that mean a week ago or approximately a week ago? Why did you need to reseat the HSF? What sort of mods did you do to it? I'd say this messing about with the cooler probably has a huge amount to do with your problem. |

| 471676 | 2006-07-18 05:30:00 | exactly a week ago, from today, monday july 17, is when I built the computer. i reseated the HSF to lower my cpu temps. It worked. I modded my heatsink by putting a fan with a higher CFM on it. I did this for a cooler cpu. I additionally attached small ram sinks to the base of my HSF to achieve lower temperatures. here is a link to give an idea of this modification. www.overclock.net I dont see how changing a fan and sticking some small heatsinks to a large heatsink can affect the motherboard. I have the mobo sitting on a desk right now with the psu next to it, and I still cant get it to start up. The fan I put on the mobo has a 3pin mobo connector. I have tried unplugging the fan and same problems. I actually dont have anything but the cpu, hsf, and psu connected to the mobo and its still not working. :( I find it really strange that the problem only occurs with the 4pin ATX, I have also tried 8 EPS, and it all results in the same outcome, the fan briefly spins and then it stops completely. |

| 471677 | 2006-07-18 05:58:00 | Is this the 8 phase power board? The only way I know of testing failure of components is to test with known good components, unfortunately for those starting out at PC building, this isnt always possible. |

| 471678 | 2006-07-18 06:07:00 | I dont know what 8 phase power board is. Sorry. It is an Asus p5wd2 premium. I am going to call Asus tomorrow and see if they can help. I feel as though I did everything correctly, so I dont know why this board died on me like this...If it is infact the mobo that is the problem |

Hmmmm. You can't? Just as a small experiment either take them off or try the stock cooler your CPU came with and see what happens. |
