Not so random reboots

LAST EDITED ON Apr-25-02 AT 09:18 AM (EST)
 
I have a MicronPC with a Celeron 733mhz processor. Recently my machine has started to continually reboot itself. Interestingly, it will reboot, and then 3 minutes and 5 seconds later it will reboot again. This gives the machine just enough time to run scan disk and then display the desktop before it reboots. When I press delete on bootup to enter the BIOS setup I can stay in the BIOS setup for longer than 3:05.

I was thinking maybe my CMOS battery was bad, but if that were the case would I be able to stay on the BIOS setup screen for an indefinite period of time, as I have been able to do? If not could it be an OS problem?(I'm running Win ME)?

Thanks for any thoughts on this one.

Check the CPU fan. Larry

The fan was running. If it is a temperature problem isn't there a way to adjust the temp at which it shuts down in the BIOS? I'll try that tonight. Also, I was thinking--I've been letting ScanDisk run to its completion. I will cancel scandisk as soon as it starts and then see if my reboot cycle is shortened from 3 minutes and five seconds. If the cycle is shortened I guess this tells me that Startup is detecting an error somewhere???

Sounds as a bad cooling of the CPU or a weakening Power Supply Unit.
(Maybe Both)

Blow out the cooler-body and the fan of your CPU.

In the BIOS, the CPU does not do much. (walking)
In the 32-Bit Software, the CPU really has something to do! (running)
The increase in temperature and current drain on the PSU can couse these reboots.
