ive been having this problem for a few days now.
While using Windows 7, my screen just turns opaque, and i have to reset my pc.
This happened :
1. Twice in Fifa 10 (exactly at kickoff, green screen)
2. Using uTorrent (White Screen)
3. As soon as i move mouse after boot up ( White)
The main problem is that my monitor goes into power-saving mode upon reset after this screen, and it does not get out of it. I have to wait a few hours everytime this happens to use my pc again. Its not my monitor, cause Ubuntu and Hackintosh work just fine. Today i got a similar black screen with XP. I have also restore factory settings in BIOS. Pls Help.
EDIT : Happened in Hackintosh as well, maybe ill restore BIOS to version that came with my PC.
EDIT : Found out a possible solution thanks to google (Damn! Why does BING even try???), Some RAM settings set to AUTO in BIOS. Will just have to give it the original frequency!
