A couple months ago my pc died on me and i replaced the hard drive and reinstalled windows, during the process i noticed that my screen was in a weird resolution and there were weird colours dotted around my monitor. I replaced my graphics card (GTX 8800 to a gigabyte 670 4gb) today and when i booted it up i had the same problem, i then installed the drivers on the disk included and now nothing will display form the card and the GPU does nothing but run the fan at full speed. Am i just unlucky in getting a bad card or is there a bigger problem. Also my pc runs fine using the onboard graphics.
