I have xfx nvidia 9500gt.
The problem is that , when graphic card is installed and windows starts the screen flickers there are black dots and color problems on screen.The windows takes to much time to load and pc slows down a lot.Then i need to restart windows after it is loaded completely to fix this issue.And when windows is working fine and i start any game like prototype or saints row the pc shuts down unexpectedly after some time of gaming but works fine without gaming.This happens every time when i boot.
All drivers are updated and tried to format pc many times and tried different os also but didn't worked.Tried to re-apply heat sink of gpu also.Help me if anyone knows solution.Thanks.
