Strange system-wide graphical lag started occurring recently
So, recently some strange FPS started occuring on my system accompanied by a constant 5-6% CPU usage of the SYSTEM process. Approximately every 2 seconds everything but the mouse freezes for half a second. This happens regardless of what I am doing (it even occurs if I have only explorer open) and is also recorded by running applications such as games.
As this never happened before, I immediately suspected that my system may be infected. I disabled all autoruns and restarted my computer in safe mode, then ran a Malwarebytes scan. The scan found no infections, but I still strongly suspect that this may be malware.
When I reboot the computer the lag seems to dissapear for some time and the CPU usage of the SYSTEM process usage goes down to 0-1%. After some time, the lag returns and the system process usage increases to a constant 6%.
Do you have any idea what could be causing this and what can I do? If I don't find a way to resolve this i will do a clean install of Windows.
