I have an IBM NET VISTA MODEL 2276, CONFIG ID#Cf20495 i’m trying to fix for a friend. I’ve formatted the hd-clean. It has all the original components it came with. I try to load win2k or winxp, but the computer just keeps rebooting. If I load it with just DOS, the machine runs fine and everything, no rebooting. Soon as I start loading any win, it starts rebooting. Sometimes it will go through the install, and get to screen right before it flashes the desktop and reboots. Tried hotswapping parts, cpu, ram, hd. Nothing works.
