I didnt have internet for awhile then i finally got it back and i had to update a lot of things so i updated my 8500gt gfx driver and a bunch of windows vista updates then i noticed in my games the video was messing up and then on my desktop and i was starting to get alot of blue screens so i try to start my computer and it wont start it just goes black and then the blue screen will pop up so i started it up in safe mode so i could restore my computer to before i updated my gfx card driver (thinking it was that,that was causing the problem) and then after that i tried to start it up in normal mode and it still didnt work then i tried safe mode and it just went to a black screen and thats it so im thinking it had to be the windows updates but im not sure how to fix my problem if i should just get a windows disk and reinstall ( cant find my disk) or if i could somehow use another older computer that has xp on it and just download the windows file on to a disk then install xp on my good computer or if i should just switch the hardrives on them
