I bought a used computer, opened command prompt, and it said the work load on the CPU is at 100% non-stop. When I order the programs from largest work load to smallest, it does not look like the programs running add up to 100% at all. Random programs shoot up for a couple seconds of work load, and then go back down (such as Microsoft Edge taking up 75% for 4 seconds, and then dropping).

The weird part to me is that its staying at a perfectly fine temp. It is idling at 32-42c and stays around 45-52c when playing League of Legends. I'm not the best with computers but if the load was at 100% non-stop, wouldn't the temps be very high? Could the thing that detects the work load on the CPU , the "gauge" messed up?

I ran multiple virus and malware services, done a clean boot of windows, and have tried a couple other little fixes and nothing has dropped it below 100%.

Can you help me out?

    ■ Your full build specification?
    ■ Meanwhile you can replace thermal grease and dust cleaning.

Start fresh

    ■ Unplug power cord, remove motherboard battery, push and hold case's power button for 5 sec to wipe fail CMOS data, wait 15 min, push and hold case's power button for 5 sec, wait 15 min.
    ■ Reinstate battery, turn on, enter BIOS, set time and date, save and exit, try play game, if still freeze.
    ■ Use self on tester (if comes with PSU), follow the instruction to read each connector output, (A), if checked out as it should, then either motherboard component's faulty or software side conflict (a) or possible...

Yes! System idle process is taking up a absolute huge portion of the CPU power. I understand what it is, but why is it being detected in the percentage? Would it mean your CPU is never going to bog down from 100% and always be working it 100% never giving it a break? Is it bad for your CPU?

Hardware side
CPU is still waiting data from RAM from storage from I/O (using internal bus such as DMI or hyper transport) either low slow CPU, RAM, HDD, ...

Software side
Try clean install

I already did a clean install of windows 10. I have fairly old RAM, should I consider buying some new RAM ?

A

    ■ Could be just bad cable, try buy and replace the cable. if after the replacement cable don't work out,
    ■ Contact re-seller or vendor for warranty.

a

    ■ Take a closer look at your motherboard and find any unusual things (flimsy surface, scratched copper lane, bend CPU socket pin, etc), You didn't tell when the freeze happens, is it right from the start you build or after while.
    ■ Log on to windows, don't run any apps or stop online (if any) updates, use driver removal tool to completely wipe graphic card drivers, this will take you to restart windows, restart, windows will install graphic card with built in driver library, use this (if available) driver and play games, if persist, uninstall windows VGA driver and install original driver, if persist, then it's not graphic card driver conflict faulty.

I

    ■ Software monitor may give false reading, get good thermal grease such as Arctic MX4, remove CPU and GPU cooler, clean and apply Arctic put back cooler.
    ■ Logon to windows and play game, if still freeze, unplug power cord, touch the GPU and CPU heat sink, they should be very hot make you can't touch 'em, if not very hot, then you'll have power delivering issue with motherboard.
    ■ To verify motherboard power delivering issue use it voltage check point (if available), if no voltage check point then use digital multi meter to read motherboard some reference here and video tutorial with keyword How to check voltage on your computer using multimeter.


At some point power related component reach its life span so one degrading power related component decrease overall power delivering performance exponentially accelerate other components reach its life span.
