I have recently updated to windows 7 professional and cleared my old OS. (3 days ago) I have been running the system and it has been just fine until this evening. This evening I suddenly got a black screen with just the mouse showing. I have an Asus P5Q Pro Motherboard and the Graphics card is a GEforce GTX260 When I reboot the system it gets to the windows starting screen Then I get a cursor that blinks a few times and then it suimply stays black and nothing happens. I already tried using the operating system restore disk and reinstalling, but the outcome was the same. Also booting in safe mode works and I can do anything needed in there, but once going back to regular boot, it does not go. Thoughts?
