Hello all, Yesterday, after turning on my comp and loading up COD:Modern Warfare, my computer completely froze. This has never happened before in the 3 years I've had this comp and I was unable to alt f4/ctrl+alt+del or do anything so I had to do a hard reset by holding the power button. When it started to boot up, I saw weird grey lines in a Matrix(the movie) like patterns running down the Bios screen. After logging into Windows via password, it seemed as if the monitor turned off and everything went black, yet the computer was still running. I searched online to see any solutions and tried disabling the video cards through safe mode. Safe mode was able to boot up, but had these plaid green squares in it, identical to the squares in the topic of "Plaid green squares and gaming issues" over at Tech Support Forums( I can't post any links sorry ) I was able to disable the video cards and after restarting, I was able to successfully log into windows. The green squares were still there and sometimes, when I toyed around with the resolution, random red pixels would be scattered throughout the screen. I tried disabling and enabling the video cards several times and it seems that when it is disabled, I am able to log into windows, but when it is enabled, after typing my password into windows, the monitor displays nothing and goes black. I also tried downloading new drivers from Nvidia(have Nvidia geforce 7950GX2) but nothing worked. Eventually I wiped the HD and reinstalled windows, downloading new drivers for all parts, but the same problem also existed. I even got solid red plaid squares at the screen where it says to choose which mode you would like to boot up in (ie Safe Mode/Safe Mode with Networking/Safe Mode with Command Prompt etc...) I opened it up and cleaned out the video card and reseated it, yet the problem is still there. I am convinced that it is the video card problem, but have no real way to test it out because I have no other computer or video card. Are there any other ways to make sure it is indeed the video card, before I go and buy a new one heh. Thanks in advance!!
