Hello, It's my first post on this forum and I really hate to be bugging allready but I cant get my computer to work properly.. no matter what I do. So any help is appreciated. Ok here's my system summary: http://img687.imageshack.us/img687/825/system2.png I'm running MS Windows 7 Ultimate (6.1.7600). Everything SHOULD be running fine.. I've updated my BIOS and graphics card driver and tried various different drivers with no success. If you look at the picture on that link you'll see these black lines across the screen. They are the least of it. I cant start any game without a freeze or a bluescreen. The thing that puzzles me the most is that these problems with 3d started just like that with no major changes in the system. At first it was something small when I was playing Call of Duty 4: Modern Warfare. Then the problems escalated and now I cant start any game. If I tried to install one now it would probably go to bluescreen. Updating graphics card drivers or changing them might cause a crash as well. I tried to run my original p5q-pro Intel P45 Chipset Suppost DVD but it says something like 'The operating system doesn't support the support dvd'. My graphics card is less than one year old and i haven't clocked it or anything.. Dont seem possible that it would've broke down since my temp's are 40-60 allmost all the time. I ran the (7100?) Release Candidate for months with great success and then out of the blue comes these problems without changing the system. Does this sound like a virus or some malware? I've installed win7 couple of times on top of the old one. Didn't format the drive though.. Windows Malware remover cant find anything and malbytes or Avira either. Also these crashes sometimes has nothing to do with any game. Firefox might crash. Explorer.exe might crash.
