I have a PC with AMD's K6 233 processor, 64 mb ram, Win95 (b version), with a 3Com NIC & ATI graphics card, in an ATX case. It has 3 internal hard drives. C-Drive is the Win95 boot drive, D-drive is a "backup" drive, E-Drive has DOS 6.22 OS. This computer is used for both windows and DOS applications. The boot sequence in the BIOS is changed to define the drive on which it boots (either the Win95 C-Drive or the DOS E-Drive). About 4 times a month (not on regular intervals) the computer actuallyre-boots itself. It has happened while in both Windows and DOS applications - on both hard drives. To me, this eliminates a software related cause. I'm leaning towards a reset switch short or motherboard cause. Any ideas different than mine?

I had a PC rebooting itself all the time. My problem turned out to be a badly-seated AGP video card, but I've also heard of a CPU, RAM, power connections, or any other cards coming loose and causing a short on the motherboard. I would remove and reseat everything and pay close attention to anything that seems to seat a little too easily or feels loose.

I would guess that either you have a defective CPU or CPU Fan. I would invest in new fan. I have several AMD machines that are very temp sensitive, the fan may look like it is running fine but it is probably running slow. Just a suggestion.

fans can indeed cause strange problems. Thanks for the suggestions. (let's see how Tech splits that 183 points!)
