My Computer:
i5-33305 cpu
Memory 8gb
Windows 8
Nivida gtx 620
600wt psu

Why is my gtx 660 not working on this computer?
My Computer at start says: the computer will not run this cpu so it changed my settings so i was able to use the intergrated graphics and they suck

Go into your bios and go to the advanced tab. Look for the southbridge and click on it. You should see the choices for video. change it to PCIe and save changes. The computer will restart and plug your HDMI cable in and you should be able to use it.
