I just purchased the GTX 960 for my computer but it doesn't seem to be working.

System Manufacturer: Hewlett-Packard
Model: h8-1213c
Motherboard: pegatron 2ad5
cpu: i7
Trying to upgrade from: GT 620
Power supply: 460W

Everytime I try installing the new graphics card the computer screen goes to a black screen after the HP splash screen as well as the motherboard making 3 beeps.
I've gone into the BIOS but I don't see an area for detecting graphics cards, I even called in my tech savvy boyfriend to look into the BIOS but he also could not find the graphic card detection.

I've temporarily switched back to the GT 620 card so that I can use my computer for now.

What could be causing the problem and is there a solution?

Thanks so much in advance!
