This graphics card is very new and since I got it I keep having problems with it shutting down. First problem was when it was shutting down with a 750 w power supply and the recommended psu is 500w. It got fixed by adding a pretty expensive coolermaster 850 w psu. Then I also had problems with shutting down after a few hours while inside a video game. And yet again I have a problem with the gpu just not working or shutting down on startup. The only way I fix this is if I connect my hdmi cable into another socket on the graphics card itself and then restart my computer.
 
Solution
does on of you tv have a pc connection for test or even another hdmi cable you could for doing it to see if it is the cable or gpu that is defective .

Thats the thing. Both hdmi ports work, I just have to switch between 1st and second one every time i turn on my pc and then I have to restart it. I didn't get the last part of the message. What is dl-dvi-1 connector?

I just remembered that it has to be the cable, because when we tested my computer in the pc shop we turned it on and it didn't happen, it went straight to the login screen. Thank you for your help anyways.
