Thank you in Advance. PC was left on for a few hours in warm room. When I came back something like hardware not detected. I rebooted, and it goes straight into a reboot loop. You get the option of Safe Mode, but once you go into safe mode it reboots as well. So after throughly searching google I tried a few settings in Bios and same result. I gave up and reloaded XP. XP loads fine, add all of my neccessary hardware and drivers. Played a few games, went on the net and rebooted loop is back. when you start pc, Asus logo comes up, windows something went wrong message, you can select safe, good configuration or normal. No matter what you select it reboots after windows logo. Please help as I am desparate trying to finish homework. Thank you.
