Ok, the other night i turned my computer on like normal and it starts doing this. After i have it on for about 25-30 mins i will hear something inside my computer cut off, kinda like when i shut my computer down just a little quieter. Then a couple seconds later my screen will change into a bunch of blocks and different colored shapes but i can still see where stuff was on my screen and can move my coursor around which turns into a block as well. If someone could tell me whats going on id appreciate it Thanks... O and here is what i have in my computer if that helps.
Video card-Radeon 9800 pro
memory-896mb
MotherBoard-Asus P4P800 SE
 
I still dont know what it is but i know my second hard drive is cutting off because when i hear the noise i cant open anything from that hard drive....

something cut off... check to see if the fan on the video card is still spinning.. If not the card will overheat and freeze the computer output.
 
I fixed it, your right it was my power supply. I had a 450watt replaced it with a old 150watt. Everything works fine now. lol
