The problem I am about to outline happens on win98 and win2000 installations. Even after formatting and reinstalling each of these O/S's once I still encounter my problem described below.
The PC runs fine in dos, when formatting, installing the O/S, booting off a CD / disk, etc.. but as soon as the installation process loads windows I start to encounter problems with the system rebooting. The 98 installation went fine the longest. Once in windows I was just starting to install drivers. I switched to my other pc, downloaded a driver to a floppy and went back to the troubled pc, put the disk in, and clicked 'next'. Instantly the machine reboots. When it came back I was able to install the driver, but after pausing to download another one and then returning to click the mouse, again the pc reboots. The same problems are encountered in the windows 2000 installation process if I take long pauses before using the machine again. (ex in the setup process I click 'next' on one screen, return 5 min later to type in CD key, click 'next' and machine reboots) This is very strange. I've encountered various problems with rebooting on some of my pc's in the past, but never anything like this. I tried another video card to no avail as well. The CPU fan is still good and the HD has been formatted before each installation. This machine was running 98se flawlessly for months and last week the machine began to reboot every 5 minutes or so, after a network print job was sent to it. The machine seems to misbehave in windows only, when there are long periods of no activity followed by any sort of activity. I am baffled, anyone have any suggestions?
