Hello community, I really need help here. I have a Optiplex 790. I was given a Sapphire R9 270 Dual-X and a Alllied power supply model SL-8500btx for a little upgrade. Everything has been fine for the past 6-7 months. I've been running dual displays, hdmi to my monitor and display port to my 4k Philips TV in monitor mode. 

Recently my computer starting having problems after a new windows update and it caused my Video card to freeze up then quit working all together. I was able to get to work with just one monitor for a little bit but now back to motherboard display. When I run the diagnostics with the Sapphire R9 270 Dual-X installed it gives me:

Error Code 2000-0332  

Validation 45056

Msg: Video memory - Video memory integrity test discrepancy

I know from reading it's something to do with the bios on the video card. is there a way to fix?
