Be very suspicious of the cards, particularly if you are using a high-end graphics card: their processors run very hot and can cause exactly the symptoms you described. It took me a week before I threw a Voodoo AGP card in the bin.

Hello again,

Eh .. there's supposed to be wires from the fan into the motherboard, is there? Because there's a place for me to plug wires in, but no wires to plug in. That certainly explains why it was reporting that the fan wasn't spinning. Thanks a million. Should I be worried that there aren't any wires at all, or is that okay?
>I had the same problem with an old P200.. It would restart for no >reason. Fixed the problem by adding a fan to the top of the CPU.
I really don't think it's a heat problem. The monitoring software I have was set to warn me when the CPU temperature reached 60. I have changed that to 35 to be extra extra certain. I brought the warning temperature for the environment down from 50 to 35 aswell. So it definitely should warn me if it's getting hot. At the moment I'm running the machine with the side off the case. The room is fairly cool too. After crashing I tend to check the temperature inside the case with my hand, and around the CPU. It's never hot.

I think I'll try that today. Thanks.
>Is it overclocked? If so, run it at rated speed.
No, I was afraid to mess with that :)

I made extra-sure that I don't have a loose DIMM. How do I tell if I've got bad RAM? And are the two DIMM modules supposed to look different? They're both 128mb, but one has black things on both sides and the other only has them on one side (sorry for such an untechnical description, but I don't know the words :)).

The CPU fan is spinning at 3934 RPM. Is that fast enough?
John asked for some specs. My processor is a Pentium III, 800MHz. I have 256mb RAM. I have an SiS6326 graphics card.
Sorry to keep bothering you all, and thanks for replying so quickly to my last email.
Thanks,
Carolan
