I am in desperate needs at the moment. I recently purchased a r290x as an upgrade from a 7950. I unplug all the power install it, plug back all the power and starts it. Then there was this pzzz sound and a string of smoke came out out my PC. I think I fry something but idk what. I think it because my power supply didn't generate enough power. But now my GPU fan won't turn neither is my 7950 fan. The only fan that turn is the power supply fan. How can I check which part is fry and which is okay? Please god let my r290x to be okay. (I try to test by plugging the 7950 back in) why do I do now? Can someone help me please!
