GTX 780ti Black screen when doing specific things

[GtheGecko]

[strike]Hey, I know the title is weird, but hear me out. I have a asus GTX 780ti with some random case fans (temp doesn't go over 75). When I run furmark for 20 mins, it stresses my GPU, but nothing bad happens. When I run Userbenchmark, and get to the GPU benchmark, the screen goes black and graphics die. I know it's only the graphics, because I still hear audio. This also happens with games when I have unlucked FPS. For examble Black ops 2. I get into the game, and after 2 seconds the screen goes black. Locking the frames used to fix it, but now even that doesn't help. Thanks for reading![/strike]

I fixed the issue. My overclock was too high, I guess my 550 watt PSU can't handle overclocks on a 780ti. After reverting those, everything is fine! Thanks for the help anyway!
