I've got a bit of an issue with my PC at the moment.
I was using it Sunday evening and all of a sudden it froze and switched off, and after that I couldn't get it to switch back on.
Through troubleshooting I've determined that the computer will only power up if the GPU (from this deal a few months ago https://www.ozbargain.com.au/node/395901) is not hooked up correctly. Basically the computer only powers up if either the GPU isn't installed, or if it is installed it will only power up if JUST the 2 pin connector (from the 6+2 Pin cable) is connected, at which point I get no display output anyway, presumably because it's not getting enough power.
If I connect the full 8-pin connector, there is a sort of click from the PSU, the case fan spins about 1cm around and the lights on the GPU sort of flicker very briefly, and nothing more.

Any insight much appreciated!
