I don't know if anybody else has encountered this problem, but here goes: I run an ALTHION 1 GHz processor. I begin the day by firing up the CPU. I'm on the computer for 1.5-2 hours when all of a sudden my cpu just shuts down, I lose everything.I have to do a cold shutdown. I wait approx. 20-30 mins. & start computer again. However, the problem re-surfaces again. Only now, the interval shortens. My computer operates this time for approx. 45 mins. & again shuts down. On subsequent start ups, the time interval considerable shortens again. I've replaced my processoe fan with a larger one but this hasn't solved the problem. I've considered replacing my power supply but this is a sizable monetary expense. I've already re-formatted my hard drive & that didn't fix this problem. Any suggestions would be greatly appreciated. pemanisky@aol.com

Check that whole system is not overheated. Try to open your case and look, if you will have "working time" increased. If so, consider buying another case or, at least, installing additional fan.

Good luck.

This does sound like a heat problem.

IF your old fan was bad or undersized, it is possible that the CPU is damaged.
1GHz Athlons are around $50 these days, so it would not be to expensive to replace the CPU.

If your system or motherboard did not come with a monitor utility, I suggest you install Motherboard monitor

You should look at both the CPU temp, and the core voltage.
If the core voltage is erratic, or high, then you have a motherboard problem.

As to the power supply, if you have less than a 300 Watt supply, and a heavily loaded system, then the power supply is a likely suspect.
300 Watt supplies are selling for under $30 at many web-tailers.
Just don't buy the cheapest as some are a bit under-powered. (I have a 250W that has better output specs than some of the cheap 300W)

I have also seen the BIOS CPU speed settings cause some strange problems.
I now set the CPU speed manually in all SDRAM based Socket A motherboards that I setup.
FSB 100MHz
Multiplier 10*
RAM clock either 100MHz or 133MHz depending on the RAM.
