 Spontaneous Reboot in Clean Environment Post a Reply  
From: Kevin on 06/20/2001
I have a PC CPU with a Cyrix 266 chip that has been a great computer for a long time. I was having problems with spontaneous reboots... for no reason. I would be in the middle of an application or not doing anything and the screen would go blank and the computer would restart.

I opened the case to see my CPU fan barely spinning. Could this be an overheating problem? I reformatted the hard disk and reinstalled Windows 98, only to have the same problem. There are no conflicts, viruses or driver problems.

Is this CPU dead? Did the heat KO the chip?

Thoughts would be appreciated.

Could be a few different things:

Bad CPU?
Bad RAM?
Bad motherboard?

Disconnect as many peripherals as you can. There's a RAM check program out there that boots on a floppy, so you can test your system with no hard drives connected.

If your computer can run for 24 hours running the RAM check utility, that should rule out the power supply, CPU, RAM and motherboard.

I had the same problem w/ a business PC and it was a bad Motherboard. Also could be the power supply.

Same problems for me. I wonder if this can be linked with freezing I always had before those reboots began... All I can say is just what I saw about this freezing problem: take a look at my thread 5 before yours.

Anyway, in my case, it is not a cpu overheat: it doesn't work at more than 40 C...

Can you post here if you find any solution that might work ? thanks. I'll do the same.

Good luck.
