GPU Fail?

So I was playing Planetside 2 a few hours ago and all of a sudden my GPU went off. Now the Fan is running but I get no video at all. My computer isn't even reading it, could it be a driver or could it just be that I need a new one. I have a R 7850 XFX I've had it for about 3 years or so. I haven't updated to windows 10, so I'm still on 8.1 so I don't think the drivers got deleted. If you guys can point me in the right direction troubleshooting this thing let me know, Please.

Thank you all

Have you stuck it into another computer? Another monitor? And what are the rest of your specs?

If you have an iGPU make sure that still works. And make sure you are still posting.

Surprised someone can still handle PS2... that game is utter cancer now with all the stuttering.

Can you check the Windows System Log?
