ok so this is what i have done up to now:
1. Loaded last good configuration-loads up powers off
2. Changed bios-restarts, powers of before loading windows
3. Loaded up windows resotre mode(windows domain config),loads up and powers off again
4. Loaded safe mode with networking-i manage to log in to windows,before loading the start-up menus etc, powers off.
5. Loaded safe mode only with ms-dos prombt loads up and working fine...which IS REALLY WIERD AND ANNOYING....i removed the latest windows update which was done on the 29th...restarted still powers of in normal windows mode,,,
I want to tryh and repair windows,but now the pc does not swithc on at all, although the green led on the motherboard is on etc...so no idea what the hell is goign on, could this be anything with my mains? the prob i have other things on it,,on the plug and they are working fine,,which is strange
