Windows 10, my machine is set to turn the displays off after 10 minutes and never sleep.
I recently upgraded to a R9 390 when this started to happen
Anytime my displays power off, memory and pagefile usage skyrocket.
Uninstalled AMD drivers and the problem stopped. Reinstalled and the problem promptly came back. csrss.exe is the one who eats up all the RAM.
No viruses or rootkits according to avira or malwarebytes.
Not really sure where to go from here
