Broken Driver or Broken Graphics Card?

[CaptainMario]

I have had a R9 290 Tri-x for about 2 years now. I decided to over clock it to test its full capability. I used AMD crimson (latest version) to over clock it. I made a profile for a game I was playing, CSGO(not to increase performance in-game, just to test it on an actual game). I OC'ed +25% and 10% Voltage with 1400Mhz for RAM. It ran smooth and thought it was safe for gaming. I left it there and played a few games. I later tried to relaunch the game. I was greeted with a black screen. I had no choice but to force shutdown. When I turned it on, I would get a black screen after the windows logo(Windows 10). After several force restarts it start self diagnosing etc. I thought it was either graphics problem or OS so I removed the power cables going to my graphics card and ran graphics from my mobo. It booted and i was able to use it. I was greeted with broken AMD Crimson. I reinstalled it and plugged in my graphics card again but I still get the same issue. How do I fix this?

You more than likely cranked the voltage up too high with the overclock and damaged your card.
You could try booting into safe mode, but more than likely your card is damaged.
"Ok, the biggest issue overclocking AMD R9 290X GPU is voltage. Adding more voltage makes this GPU demand much more power and generates a ton of heat."

For future reference, you should use a stress test tool when trying to find safe overclocks.

How hot was your GPU getting when running the games?
