Has my GPU just died?

Last night my PC was working perfectly. I left it on overnight, got up for work in the morning, browsed online briefly then hit shutdown as I collected my things to leave for work. As I was going out the door I heard a generic windows error sound.

Arrived home from work this afternoon, went to power on my PC but my monitor wouldn't come out of sleep mode despite being able to hear the windows startup noise through my speakers in the background. It's worth noting here that the usual startup jingle was distorted and elongated by about 2-3s.

My first thought was to check the DVI cable. No luck. I plugged my monitor into the motherboard to use the integrated graphics, that's the only way I am currently able to get a display.

Possibly related is that my CPU cooler fan is currently not spinning either. In device manager, my GPU (GTX 770) isn't even listed, however the fans on the GPU are currently functioning as normal.

My current troubleshooting steps I've tried are:

Reseating GPU.
Reseating GPU into PCI slot 2
Clearing CMOS.

Unfortunately I don't have another machine here that I can try the GPU in so I can't rule out a potential PSU/Motherboard fault either.

Any advice would be great.

If i try to install fresh nvidia drivers, the dialog box shows:
This NVIDIA graphics driver is not compatible with this version of windows - strange because i definitely downloaded the windows 7 version
This graphics driver could not find compatible hardware.

Don't think it was that particular version I tried, however i just tried the exact one from your link, same message. No compatible graphics hardware.
CPU fan isn't spinning regardless of whether i'm hooked into GPU or onboard.

Don't have another system to test with unfortunately right now.

Heres my HWiNFO screen

It shows up there I think? I've never used this program before so i'm unsure, obviously that big FAKE label is pretty concerning to kick off with.

I've manually checked to make sure all the power cables are properly connected today. I even swapped out my GPU's power cable with one fresh from the box. My PSU is a Corsair CX750M.
