Coming here for some help because you guys have fixed all my problems in the past.
This time i encountered an unusual problem for every time when i power up my PC and it is going to boot into normal mode; it just powers down.
I have inspected all my components and found they are all working properly, and I flashed bios when this started to happen, and it didn't help. what's even weirder is that 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.
By the way, i am using windows 8 beta and the syetem is 6 months old.
many thanks in advance.
