Problem with GPU fan and display

[SneakyCharlie]

Hello,

Lately I've noticed that the fan on my evga gtx 770 reaches full speed suddenly and there is no output on the screen. This first happened while I was gaming but after a while it started happening even when just browsing the internet.

I've contacted evga regarding this issue and they said it could be the 12v rail. So I checked it in the BIOS and it was around 11.6v. They have agreed for a RMA but now I'm thinking it might be the psu and not the video card. I haven't sent the card yet because of this.

I'm hoping someone could help me so I know if I should send it or not, or contact corsair regarding the psu as it is still under warranty.

My specs are:

Motherboard: Gigabyte Z97-HD3
CPU: i5 4670k 3.5 GHz
RAM: Corsair 8 GB DDR 1600 Mhz
PSU: Corsair CX750w modular
GPU: EVGA GTX 770 2 GB superclocked

What makes you think its the PSU doing this and not the card?

Maybe the psu cannot provide enough power when the gpu requires more.

I'll RMA it but I doubt I'll be able to return it as I got it over a month ago.

As an update, I've received my RMA but I've got the same issue but now it occurs randomly, not only when I play games. Does anyone know what might be wrong?
