my computer crashed mid way and when i came back suddenly everything has gone bad. extreme fps drops very fast constantly. msi afterburner shows gpu usage spiking from 100 to 0 then back very fast like a lightning bolt. i tried uninstalling all drivers and amd radeon software but now it just says class not registered everytime i log in and it continues to lag. need help its impossible to play games or even use the computer in general.
Radeon r9 200 series
then spikes in the picture are way higher when im playing games, there is never a mid point its either 100 or 0 but it never sticks
