Need help with computer problem

[jediphx]

Have a friend that is having a problem of after a while their mouse will lock up and they have to reboot the system to unlock it. I opened the case and saw that the fan on the chipset of the motherboard was unplugged so I plugged that back in and we thought the problem was gone but after i left they called me back to let mw know that it locked up again. I checked the bios and did not see any settings gone awry from what i could tell. They also said that they have turned the computer off using the power button and later on the computer had turned itself back on again. Thye did have a bad cdrw drive that was slowing or causing the system to become unresponsive but I unplugged and removed that as well. Any ideas guys? they have a amd 2600+ which i think the voltage was set to 1.66v if I remember correctly. Also cpu at idle is running at 30C which i believe is fine for that processor. I checked their outputs on the PSU in the bios, most or all look ok some a little low but that is not unusual. I still have a sneaking suspicion that maybe the PSU could be the culprit?

Could it have something to do with the power supply?

give him your psu, and see if the problem goes away.

Does it sound like a PSU issue?

well system hardlocked in the screesaver after about 30 mins to hour even with a new 450w psu in it so thats not the problem. I also ran memtest for over 2 hours and no errors there. Could a bad or overheating video card cause a hard system lock. There system is not a gaming system though I dont even think they have a 3D type card in it. What else can i do guys? Mobo looks brand spanking new and I dont see any leaking or bulging caps either.

What model of mobo is it?

if I saw a cpu fan unplugged I would be tempted to closely inspect the cpu and socket for damage?

 

[jediphx]

it was the chipset fan that was unplugged not the cpu. Its a gigabyte mobo I have to check the model# I know its a VIA chipset. I think the K400 chipset or k600 something like that

Try bumping the fsb down 5 or 10 mhz. Also the chipset might have heat damage.

how do I test the mobo or chipset for damage? Also i did notice that there were some warning messages in the event lister in admin tools that stated HD had bad blocks. I need to get my friends admin password first before I can test the HD
