Ive just recently had my computer assembled, and it seems to be working perfectly except for one major flaw. The comp hasnt been able to play a single game properly. Apparently the rig should have no problem running Far-cry. But every time i load the game, i get a screen which is completely shot; all the colours have a high contrast between very bright yellows, greens, and blues, against a predominant black.
I then tried installing Star Wars: Knights of the Old Republic (KotOR). After the intro sequences, I am left with just a "black" screen, I cannot even view the menu options, let alone load a game.
At this point all the updated Nvidia drivers had been installed, but they had absolutely no effect.
I thought it could be a video card problem, so I then removed and uninstalled the 7800GT, and put in an old Nvidia 5300 that worked on my bro's old computer. After installing all the drivers provided on the installation CD, KotOR actually seemed to run. I was able to view the menu screen, and load games. But then 5min into the game, the screen would become completely black - just like before -but then return back to the game dynamo. Then 10min into the game, the colours would again be shot with extreme contrast (similar to that in Far cry).
It seemed to me that KotOR was not working because I had not as yet installed the latest Nvidia drivers, but at least the game ran, unlike the 7800GT. I concluded -perhaps incorrectly- that the 7800GT was the problem and I then contacted the relevant parties for its return. I thought everything would be solved by the installation of the updated Nvidia drivers. wrong. After installation, i had the exact same problems as the 7800GT, the menu failed to load and all i have to see is just a frustrating black screen.
Any help on this issue would be greatly appreciated. The 7800GT will be sent off for return shipping in less than a week. If somebody could help me I would be very much thankful.
