    High CPU usage on all programs for no apparent reason


    Hello,

    I have two PCs, one at home and one at my university. Recently I used my home PC SSD and HDD and put them in my university PC. The two PCs have separate hardware, and everything worked fine on my university PC after I installed the proper drivers. However, when I put my drives back into my home PC, all games and softwares I use cause extreme CPU spikes and only 30-40 FPS on games I previously got 60+ FPS on. What I've noticed is that when looking at the total CPU usage in task manager that there is an unaccounted amount of CPU usage usually around 20-30%. Another thing I've noticed is that rapid mouse movements cause a CPU spike as well, usually getting it from 0% to 50% usage. The CPU temperature isn't high either. I've tried multiple solutions such as updating all drivers, resetting windows, changing power supply options, closing all background tasks, running virus scans, optimizing drives and repairing drives, and using WPA but have had no luck. I'm convinced that the issue is related to the CPU having the settings of AMD Ryzen my university PC CPU instead of AMD Fx-4350 settings my home PC CPU.

    :)

    high cpu usage

    After downloading windows 10, anytime I run any programs, I get high CPU usage. It does not matter whether it is google chrome, task manager, playing games, whatever. Anything seems to spike the CPU usage. I have already run malwarbytes and my antivirus
    programs and find no viruses. Any suggestions? Thanks.
