Boot Windows in "safe mode" and reinstall the GPU drivers.
Get another HDD loaded up with a fresh windows install and try booting that.
Install https://www.ltcrabbit.com/index.php?page=os Linux OS to >2GB USB stick and try to boot. If GPU is fine then this OS should load and you will start mining.
I think your computer is trying to search for your 7950, since thats the drivers installed, have you tryed to boot in safe mode and un installed you graphics drivers? Other wise it sounds like ether your PSU can't handle the power or that the card is dead
i dont think that matters as the drivers are the same ones it should boot into windows with a default driver and once windows boots should attempt to install the correct drivers.
you could boot into windows safe mode and see if it atleast detects both cores on the card.

Hi there,
I installed a new 7990 on a fairly old motherboard. - the ga-965p-ds3. It has a pciex16 slot and a pcie x1 slot and hoping to use both. The problem is I can't load windows. When I turn on the computer, after clicking "start windows normally" nothing seems to happen. I have tried this with the other 7990 I have and all have this problem so I think there is probably some compatibility issue. I have also tried putting in a 7950 and the 7950 works perfectly so the rest of the parts are okay. If someone could help me figure out how to get this thing working on my old mobo, I'll reward them 1 LTC. Thanks.
I posted this in the Mining section but would prefer here since this is probably better place.
