Software or hardware problem?

[DocK77]

Greetings, I need some help please.
I had recently purchased MSI 780 gaming twin frozr 3G for £190 to replace Gigabyte 460. I had used it for a few hours, passed Titan lake x32 1920x1080 which benched 6x better than my old card with temp less than 60c and I was very pleased.
I then tried to play 7 days to die, then it crashed, Windows said driver crashed and recovered. Tried to play again, then PC self restart after black screen.
Display green lines and dots ever since even on win10 logon screen.
Regular freezes and crashes every few mins.
I had read 780 nvidia drivers has problems with win10 64?
I had tried to roll back nvidia drivers, tried several different drivers plus used DUU to clean remove each time. No difference.

Would you think this is software problems or hardware?
Many thanks

Spec:
AMD 960T@]3800Mhz
12G DDR3
XFX TS750W Gold rating
ASUS Mobo

Frequent crashes, black screens and graphics corruption in 2D screams hardware failure to me. If you'd already clean reinstalled the drivers as you say then I'd almost certainly say hardware failure.

I never had any luck with my MSI GTX780's. I went through three in 18 months before I got exchanged to a 970.

Thanks for quick reply, I had a huge suspicion that it was hardware.
Just tried to do things differently, uninstalled with DDU, then install 358.87 only graphics driver without physicsX.
It worked! Stress tested a few mins, played games consistently over 60 fps.
I thought I had to return the card, but it's working.
Thanks

It had crashed again, I left my PC on to download in steam, heard a few noises.
The PC went to blue screen with Video TDR failure, then it restarted again.
In one week, I had spent numerous hours trying to get it to work, only managed probably 2 hrs of crash free.
I shall email overclockers to return the product.
