I recently bought a Zotac GTX 770 from ebay.com, and it works on safe mode/without drivers. Whenever I install the drivers and restart it in normal mode the monitor goes to sleep and says no input detected.
Keep in mind this is not a new computer nor a computer I have built, I just placed a new GPU in the only PCIe slot it had.

Specs:
Windows 7 Ultimate (64-bit)
AMD Phenom II X2 521 ~3.5 GHz (x2)
6 gb. RAM
Zotac GTX 770 2 gb.

I tried drivers from the CD, Windows update, and the nvidia website, and neither worked.
The problem seems to be with the drivers, not the GPU, because it displays without the drivers, but doesn't work with them installed/enabled.
If more info is needed please tell me

I tried drivers from the Zotac CD that came with it, the drivers from the nVidia website, and ones that automatically get downloaded and installed from Windows Update. Each one was used by itself without the others.

The only selections were "ONBOARD" or "PCIE", and it switched automatically to PCIe when I restarted my computer (I checked).
