Just put my 7970 in and nothing fans and lights on but no drive noise and blank screen. Tried the onboard GPU and still nothing.
Given up for now but looking like it might be an interesting RMA.
I'm gutted for you. I know this might be a stupid question but have you reset the CMOS?.Just put my 7970 in and nothing fans and lights on but no drive noise and blank screen. Tried the onboard GPU and still nothing.

Mr Castiel you are correct it does seem the mobo is at fault as well as the 680. The pop and smoke was a cap going on the motherboard and the GPU sucked up the smoke and blew it out the back.
I have replaced the blown cap on the board and it is working again now and has been running prime for 2 hours on the onboard gpu without any problems.
Plugging back in the 680 I have exactly the same issue as before with the drivers crashing and then the blank screen.
I'm now going to go with my original plan and start from a fresh install of windows and work from there but at least my board and CPU are operating ok now.
All good fun.


Just tried the card in another machine and it works perfect. Just tried another 680 in mine that works fine and same problem.
It must be something with my pc, but no idea. I think I will strip to basics and start afresh. Seems weird the AMD card works perfect.
I will not give up....![]()
