I had a problem awhile back with the About:blank virus. I managed to finally rid myself of the bug. However, in the process I must have done something to my system. Whenever I try to play video, enter certain websites or run certain programs, my system goes wacky on me. My screen goes blank (black) intermittently and sometimes completely freezes up. I then have to reboot and avoid those programs.
I'm considering cleaning my HD and re-installing Windows, but I know its a big process and I've never done it before. Unfortunatlely, it's been awhile since the time I first started seeing this problem, so I can't pinpoint what I might have done to cause it. Can anyone identify what my problem might be, so I can avoid this lengthy solution?
