unexpecting shut down problem?

[goplaytetris]

I just finished building a computer for a friend of mine. it boots and runs and has windows xp professional on it. but for some reason when he downloads anything it causes windows to fuck up and restart. any ideas on what the problem is?

Check the system log in the event viewer. You may be able to find is causing the sys to FUBAR from there.

Otherwise, it may be a driver issue. Try upgrading everything.

Maybe a Heat issue?

Post some details about the box.

its an x-dreamer case off new egg. it has 3 case fans. front side and top. i have mbm 5 installed on it and the processor stays around 35-40 degrees. it has an athlon 2400+ in it with a 3200 compatiable heat sink. the mb is a shuttle which has worked in the past. it has two 512 sicks of pc 2700 generic RAM from new egg and a 120 gig hard drive. theres no way it could be a defective hard drive or ram? it only restarts when you download something onto the hard drive or when you open windows explorer to browse the hard drive.
