Well i bought a Geforce GTX 660 Graphics card and whenever i hook it up to my system through the PCI-E port it just leaves a black screen. My computer has integrated graphics on in Intel HD. Well i can run it fine while plugged into the onboard graphics but with it plugged into the new card i cant even make the screen wake up it just stays blank and cant access the bios with it or anything. I have a new PSU thats 600w and the graphics card only needs 450 so thats not the problem and its all hooked up to the power as well.
