Ok so let me start. Every time I play a game such as SimCity 4 or my bro plays a Cartoon Network game on the webstie, my computer shuts off. Before, like 5 months back, it didn't do that when I did these things. I don't know why but it also happened when I was watching a youtube video and ripping a CD. I don't know if it has to do with RAM (I have 1 Gig), and why does it shut off?!?! I don't know if it has to deal with the fact that I haven't cleaned or dusted my computer. I have no viruses or nothing like that and I mean it. Also, I had these computer a couple of years back with the suckiest things ever (20 gig hard drive, half a Gig ram) and I could play these games easily and effortlessly. I don't know what is causing this and it's pissing me off because there is no solution. Please Help!!!!
