Lately I've noticed that, quite often my computer will become very slow. When I open the process panel in task manager it shows that the system is hoarding the CPU usage. Is there anything I can do to fix this?

virus?

you first need to find what is using 100% CPU.
take a look in the task manager, click processes tab and sort by CPU usage.

My AV doesn't detect anything?:confused:

It's the "system" that is taking up most of the CPU usage.

Have you installed anything recently? Apps? Drivers? Games? etc.

boot into safe mode and see what happens there.

PS: What version of windows are you running?
