I have two cards, 5850 and 7950. I'm using 5850 for primary and when I got up this morning, I noticed that there is no display on monitor. I pluged it to 7950 and nothing changed (plus it seemed harddrive didn't response). I restarted the PC, everything works well with 5850 but same with 7950. There is display on both BIOS and safe mode from 7950. So I decided to uninstall and reinstall the drivers. When the installing is nearly complete, the screen went black again. So this is a technical problem? What should I do? (I have been using the both cards for mining about two weeks). I have Win 7, 750W PSU. Thanks by advance.

for starters remove both graphics cards, and try with the motherboards display ports, if works then plug them in, while off or running, you choose i did while running and the display went out, all i had to do was pug into card, i'd recommend while off if you aren't up to it.
If not your motherboard my have a problem or both your Graphics cards have a problem, if so it could be moisture damage, or a failure.
speak to the producer off the Graphics cards/Motherboard for a replacement if warranty is still active, only if the last solution is what you think it is.
I'd also recommend you send them a email about this problem if you have access to the internet.

I hope this some help for you. :)

Thanks for the quick reply. But I don't have a plug for onboard GPU. I disconnected 5850 and just tried 7950 and again black screen also harddisk lights stopped. It seems to be a hardware problem.
