Possiable motherboard problem

I am trying to fix a friend's computer, i believe it has a jetway b88 motherboard in it. Just recently i installed some new memory, a new graphics card and reformatted the hard drive and loading on a corporate edition of windows xp. I then loaded on all the drives, updates and software and tested it a number of times, everything worked perfect.

It then was stored in my girlfriends spare bedroom which was about 60 degrees for a month until the friend could come and pick it up. He set it up in his new house and turned it on it was completely dead. I immediately replaced the power supply and now it comes on and loads windows xp but after about two minutes it turns itself off. It usually takes about 3 or 4 tries to get it to turn back on and then it does the same thing again.

Any suggestions as to what is going on, right before it turns off it sounds like it is trying to access the hard drive , i hear the disc bounce a bit and then the computer turns off. My guess is that iit's either a bad hard drive or there is a component on the motherboard that is failing, any help would be greatly appreciated.

Hi tcman41,

This sounds like an overheating problem to me, most likely the CPU. It's obviously booting and then reaching the max temperature that is set in the bios and shutting down automatically as a safety precaution.

Check to make sure the CPU is seated properly and that the heatsink is properly installed.
Another possibility is that the graphics card overheating, although this is less likely.

In the past I've heard this problem being solved by simply reapplying thermal paste on the CPU or reseating the heatsink to make sure its secure.

hope this helps

ok sounds like a good plan. let me know what happens.

Go to the bios and check the maximum temperature before thermal shutdown?
