Win95 Spontaneous Rebooting

My wife's Win95 machine (Intel P-120) recently started rebooting apparently on its own.  The rebooting occurs every 20-40 minutes, regardless of the applications running.  I've checked the CPU fan, and it's running properly, so I doubt that it's a heat-related problem.  Hoping to isolate the source, I did a Shift-F5 boot (clean), and left it at the DOS prompt for over an hour.  During this time, the system did not reboot, so I'm led to believe that one or another Win95 driver is responsible.

On the other hand, I'm told that a CPU idling in DOS mode isn't going to generate as much heat as a CPU running Win95, so it may yet be a heat problem, and not a driver problem.

The only program recently installed on her machine was Quarterdeck's "Winprobe" software, which I uninstalled, hoping to correct the problem.

Since this didn't work, how can I hope to remedy this?

I'd hate to spend $150 on a new P-133 only to find out that it's a driver causing the problems.

You can have a video driver problem.  If LOCAL=EGA$ in not in the 386section of yur system.ini the video card in not local to each session.  If the system doesn't prompt you to enter safe mode on reboot give this careful consideration.

Verify that if you are using an interupt for the VGA card that the cmos setup option is enabled.  I do not recomment using an interup unless your board does not give you an option.  Check to insure that the chips on the video card (and motherboard) have not started working loose due to expansion and contraction.
Heve you combed your registry ans ini files for leftover Winprobe references? I tried that app and found it very unstable.

Kudos to smeebud!  :)  I used the Win95 "Registry Editor" to seek and destroy all references to Winprobe.  After 6-8 hours hours of operation, the system is still running smoothly.

Does Quarterdeck know about this?  I also have problems with Winprobe to a lesser extent; as long as the "Crash Shield" is running, my system locks during the shutdown procedure.  If I disable the Shield, shutdown is normal.  Go figure.

In any case, many thanks, smeebud!
