Hey guys,

I just moved my PC to a different house and when I turned it on it wasn't displaying anything. So I unplugged my DVI from my 770 and plugged into the motherboard's VGA instead, and managed to get a display.

I checked my device manager and it only lists the standard VGA graphics adapter, not my 770 card. But the card still seems to be working, the lights are on and the fans are spinning, it's just not being recognised.

Any ideas?

CPU: Intel i7-4770 (8 CPUs, 3.4GHz)
GPU: nVidia GTX 770
RAM: 8 GB
OS: Windows 7 64-bit
