Arghh! Win8 won't start

Hi.

I have Win8 installed on a home build pc. (Or Win7.5 as Logan calls it.)

It all worked fine until now(Even though it wasn't a legal copy) but when try to start the PC,

it loads the blue windows icon, and then the screen turns of and on repeately for some odd reason.

It isn't a problem with my graphics card, since i have tried to unpluck it, and just use the graphics card that is build in my intel processor.

I have also tried to recover the PC (With no luck). I've even tried to boot it in safe mode, but the same thing just happens again.

It could be a virus, but i'm not sure.

Do you guys maybe know a possible fix for this?

I would love to get some help :-)

Reinstall.

Dammit :/
