I have a HIS R9290 4gb, a 990fx Extreme 6 motherboard, a FX-9590 processor, 32gb 2400 ram, and a Corsair RM 1000w power supply and every game used to run great but now even the old games have a pulse lag and have to be run at 30 fps. When it's not locked at 30 the benchmarks look like an EKG. Up and down every half second. This all started a few months ago and it's driving me nuts. Uninstalled every trace of drivers and tried different drivers, Installed a fresh copy of Windows, Updated to the latest bios, and every other solution found on Google has been tried. Is my GPU dying? Please help if possible.
