Both fans are working. I took the side cover off and used a room fan for additional air. The maximum temp of the cpu was 98 degrees F when the computer failed. I have a pentium III chip and a JETWAY mother board.
I removed all the progams I had on the machine and reformated the hard drive. No problems on that. I then installed Windows XP Professional with SP2, and again, no problems with that. I did a chkdsk on the hard drive and that came back with no problems. It has a hard 40GB hard drive that is partioned 5GB FAT and 35GB NSFT (not sure if NSFT is the correct term but it's the "other" file system).
It seems that the problem starts if I'm running a program that has lots of number crunching. For example, I put on PhotoShop 7.0 and loaded a really big file, then I did an image size change and made it something like 1400 pixel per inch. It will work for a while but then suddenly stops and reboots.
The strange thing is that when it fails it won't reboot right away unless I wiggle the ram. If I let the computer sit for a while it will startup just fine without any "wiggling" of the ram cards.
If I run IE6.0 I usually don't have any problems of it rebooting.
Is this possible: Can the heat sensor (if there is such an animal on it) for the cpu or other be broken and is sensing a critical heat value that isn't really there and shutting down the computer?
This is driving me nuts!!!!!
