Hello, I have read some of the other R9-290 threads and tried most, updating bios, deleted all AMD folders, reinstalled after.

problem:
Had 2 R9-290's in crossfire for past 3years or so works fine have a OCZ 850PSU gold (6yrs-7yrs old)
one day went to load up Total war warhammer, and heard a loud blowing then a blue screen, with a data dump. (forget the msg)

Trouble shoot via changing pci slots (still trying to run 2 in crossfire) was fine till any game called for more gpu, then it would crash. Tested card by its self will boot, up but anything that requires gpu load black screen. Not the blue dump screen.

So my other R9 works fine by its self in ether pci slot.... Not sure how to figure out what is wrong with the bad card. really need the extra frams ;)

thanks everyone
 
Solution
My guess is the the bad card has a failing component that only works until the load gets to be too heavy... then conks out. Not much good as it is...
