my problem is that my r9 280x starteda acting strange when playing crash and vertical lines once in while then everytime when i play and now i cant even post monitor just says going to power save so i dont even see bios etc. I have tried everything changed thermalpaste reseating, cmos battery etc. My psu is thermaltake 750ap. My computer works fine with my gt 1030. even tried removing driver for 280 and trying again but no luck. before no posting i was able to update drivers hoping that will fix crashing but no luck. NOTE: 1030 is loaned from my friend so i need a fix quickly to use my pc for schoo
