GTX 970 Driver crashing

Hardware Hub GPU
1

So after giving my old gpu to my friend I got a ASUS Strix gtx 970 and decided to do a fresh install of windows 10 (via windows 8 fresh install then upgrade). Everything was fine for the first few hours then my gpu driver crashed and then when my pc rebooted windows wouldn't boot. I reinstalled windows 10 (directly) and downloaded the latest windows 10 drivers for everything but I still can't play a game without my GPU drivers crashing. Can anyone help?

Did the 970 work fine before Windows 10?
Either way test the gpu (install drivers, run stress tests etc) in another machine (your friends) if it shits itself in his then RMA it.
