Problems with drivers/gpu

Hello, yesterday I was just strolling thru the interwebs, when suddenly my screen went black. Tried to start the computer up in safe mode and in low-res, nothing worked, so I re-installed my windows. Everything was fine again, until I installed both Cpu and Gpu drivers, then the computer would go up to the welcome loading ( http://img24.imageshack.us/img24/8675/windows7welcome.j... ) and I'd hear the windows sounds, thou I'd have a black screen and my tv/monitor would show that it's not hooked up to the computer. Also, if I set my res in safe mode bigger than 800x600, the only thing I'd see is a the very top of the screen ( where it says "Safe Mode" on both sides ), and the screen is around the size of the mouse cursor. Right now I'm sitting in the normal windows ( not safe mode), without any cpu/gpu drivers installed and everything is working fine, so I really don't have any idea what I should do. Suggestions?
