Help! I can't play any games on my computer!

Okay, everytime I start playing a game on my computer, I get a bunch of artifacts about 10-20 seconds into the game. If I don't quit the game quickly, my computer will freeze and I have to reboot.

I have an 2.4ghz P4 processor, 6600GT AGP at stock clock speeds, 1 optical drive, 1 hdd, and a pos 220w Compaq psu. This is the setup I have been using for the past year and a half and I have had no problems up until a few days ago. The core temps on the 6600GT only get into the high 60's to low 70's when I try to play a game and in the mid 50's at idle. I am guessing that my psu is the problem, but I am not sure. Any help would be appreciated.

yeah the psu does sound a bit.. poo 

Try cleaning the inside with a can of pressurised air.jachichorro

I just cleaned the inside of my computer about a week ago because I was getting ridiculous core temps. It helped the temps but it didn't prevent what happened. My friend got a new computer so he will probably give me his Antec 400-450w psu.(I don't remember the exact wattage) If I get it I will try it, but for now I'm stuck.

They all run fine. I can max out fear except with medium textures at 1024x768 and I get 50fps on the stress test. Oblivion chugs a lot in the forest, but it can still look good and still be playable. BF2 runs on medium at any resolution up to 1440x900 because I am so cpu limited. Well, they would run fine if my computer was working right...
