OK, here is my problem. The computer just has a mind of its own. It starts and shut downs as it wants. the PC us usually on 1-2min than it starts to shut down normally. Most of the time to PC is on 10-20sec before it shuts down or restarts. Here what I did: -I took out everything that is not essential for basic computer running. -I have bought a mew PSU. -I have reseted CMOS. -I have tried to reinstall windows, but it managed to shut down after 3min into installation. -I have also cleaned it out (dust and crap...) What could be wrong?
