I have one realy unussual problem, every time I power up my PC and he is going to boot into normal mode; he just powers down. I tried everything my components are working properly, there is nothing wrong with them, and I flashed bios when this started to happen, and it didn't help. I can't install none of operating systems, beacuse when it is going to finish installation and he is entering normal mode, PC again powers down. But! Windows 7 (MSDNAA Professional) can boot in safe mode without any problem, but not in normal mode.
