PC Crash to black screen with delayed sound looping no BSOD message

Yes Golden is correct, the PCIe slot could be faulty or it could be too much heat in the PC (i.e. not enough airflow).

Ok so I decided to do some more troubleshooting and I did some CPU tests with prime95 and I didn't crash after 15mins. I did crash randomly on the desktop some minutes after closing prime95 and within 30 seconds of logging into windows I crashed another 3 times.

On the 3rd time it displayed the message "PLEASE POWER DOWN AND CHECK PCI POWER CABLE CONNECTION TO THIS GRAPHICS CARD"

Could this be the PSU at all or is it the GPU still?

What's your power supply?
I doubt it's that though, did you test a different graphics card?

600W Enermax Bronze 80-86%,

I just opened up PC and this is really embarrassing but somehow on the 6+2 pin power cable the 2pin part had come loose even though I've never touched it since installing it, I just firmly pushed down and felt it slide more into the graphics card and now I've run my game for over an hour without a crash so far, I do have a GTX 660 on call if my problems persist but I think it's fixed for now, thanks for all your help.
