Yesterday I was changing out my WLAN card because 8.1 was giving me problems..I was in a rush n wasn't thinking and pulled it out while the system was on. It touched the back of my MSI r9 270x 2GB card n it sparked and caused the system to shutdown. I was able to turn it on and the card works but not fully. Before I was able to play most games at 1080p on highest settings with 60fps. Now it shutters so bad I get fps around 30. I switched out my card with my HD 7770 n it also shutters bad too; it never did that on that card either. So I don't know if it's the pci-e, the card or the whole mobo.
I'm using an AMD fx-6300 with a gigabyte 970a-ud3p mobo. The weird thing is I can run furmark and look on msi afterburner n see it running fine but in game the gpu ussage jumps up n down drastically.
Any thoughts or ideas?
