My computer won't start and goes into an endless loop.
when I start my computer it works fine until it goes to the windows logo and then restarts and the cycle never breaks.
I have tried to press F8 and then press "Disable automatic restart on system failure". and after some moments I get this blue screen:

Please help me, i am really bad with computers so please guide me step by step.
