Hi, I upgraded my GPU (from HD 5570 to HD 7770) and when I turn my PC on, it says no signal. black screen... When I remove the new GPU and connect to the mobo, the no signal is gone. I tried putting the old GPU back in and everything is working too so the problem is the new GPU. I have tried to use Guru3D's display driver sweeper and device manager to uninstall the old GPU's drivers but still it won't work. Please help...

CPU - i5-3330
Mobo - GIGABYTE GA-H61M-S2P Rev 2.1
PSU - Cooler Master Extreme Power Plus 460W RS-460-PCAR-I3

Yes, I plugged in the 6 pin connector... so don't ask if I did that

Could be that the 7770 isn't getting enough power, or there is something wrong/at fault with the 7770.

If you have access to another rig that's good enough to run the 7770, you could test it.
