Cant Load Windows

[g4mer]

Problem is when i turn on my pc, after a boot screen i get blue screen for about 2-3 seconds with text, and then my pc restarts and all over again. I can't load windows now. Im 100% sure that the problem is not virus because i just installed clean Windows Vista Ultimate. I cant read the text, its too fast, but i see something like dumping memory and when it gets to 100% then restarts. Theres one time i didnt get that blue screen, but monitor didnt turn on. So i left it with monitor off and after 5 minutes it restarted it self again. What the hack am i supposed to do. Oh, i installed AusLogic boost speed and disabled sys restore, super fetch, enabled lvl2 cach and disabled applicated compability engine. maybe that caused the problem. Im reeeaaallly angry. Please help before i turn my pc into pieces.
