- Did you check 'Show processes for all users' in Task Manager?
- What does Resource Monitor say about processor usage?
I've been using this laptop for a while but, seemingly randomly the CPU usage has jumped to 100% and stays there constantly, whether I'm running anything or not. If I'm not running anything it might dip to 94% at the lowest but it never goes any lower than that. My computer is obviously painstakingly slow, but I can't find anything with high CPU usage in Task Manager.
I've tried quite a few solutions but nothing seems to help. My first thought was malware but I've run scans with several different antiviruses and they've all come up with nothing. Any help would be greatly appreciated.
OS - Windows 10 home 64bit
Processor - AMD A9-9420 RADEON R5 3.00 GHz
8.00GB installed RAM 7.46GB available
Oh, and my copy of Windows is legitimate & activated - just putting that out there since according to the solutions I've been trying this seems to be a big issue with pirated copies.
