Okay. This didn't go too well.
Turned off comp. Took out my nvidia and put in my old ATI 9200se. Powered up into safe mode, uninstalled nvidia drivers and used drive cleaner aftewards. Restarted and before I got to install the ATI drivers got a blue screen. Said "bad_pool_caller" and a few other things about if i recently installed new hardware to disable or remove it. Dumping physical memory and so on. I restarted and then it went back into windows. But nothing really worked it was like it was lagging at the slowest rate ever. Turned off computer and decided to abort testing ATI card and reinstalled nvidia card and its driver.
And here I am....
EDIT: BTW, before all that I tried 3DMark05 program. Can only try the trial version, clicked to run a test and it caused the screen to blink a lot and then just went black until i hit escape. That's all I can say from that =\
