I've googled every possible question that I had, but things that I've tried haven't worked. CTRL+ATL+DEL doesn't work, System Restore doesn't work, I've installed programs other forums suggested, but that doesn't work either. I've considered using advanced recovery programs in the Control Panel, but they require a Windows installation disk, and I don't know where that is.
This is my first time actually posting my computer problems and I really need help. My computer's been like this for a while and I need it to finish school work right now.
Also, I'm thinking that recent games I've downloaded (Like the Sims 3 and Dead Space 2) might be the problem. Maybe they aren't, but that's really all I've done before the problem in the computer started.
