Windows 10: 100% CPU usage until opening task manager. System interrupts

I shut down my comp 2 days ago. Turned it on the next day and am having 100% cpu usage. I open task manager and it works fine for a little while then it goes to 100% again.


I've run multiple virus and adware scans in safemode. No viruses have shown up. I did a complete windows reset with full wipe. All my drivers are up to date.


If anyone knows how to fix this let me know.

high cpu usage when task manager is open

i am having issues with cpu usage when i bring up the task manger it shows that cpu usage is 59% with the task manager app using up 30-40% cpu usage in the performance tab it show that my cpu usage is at 80% usage but when using other programs to check
my temps and cpu load etc is shows low 20s when gaming this can pin the cpu up at 100% in task manger

 

Task Manager High CPU Usage

I have the same problem myself with it only happens when I scroll through task manager and open and close it. I don't know this for sure but the reason this probably happens is that you may have a lot of processes running and task manager is using a lot
of the CPU to process the usage of each program.

What I have done is disable data that I don't need to see like network usage and GPU usage and it drops the CPU usage a bit. I have also enabled everything and scrolled up and down on it and task manager uses almost twice as much.

I would suggest disabling everything but CPU, disk, and RAM, (I would not suggest having GPU on because it is almost always at 99% unless you have FPS limits).

 

atheros ar5005g causes windows 10 to have system interrupts and 100% CPU usage

Hi,

I have an ACER Aspire 5100-3357 originally on Vista Home Premium 32 bit. Upgraded to Windows 7 Home Premium 64 bit, then free upgrade to Windows 10. The install took 24 hours and very slow processing after and not full functionality. Task Manager showed
high CPU usage due to system interrupts. Had BSOD. Started disabling devices and found the Atheros AR5005G wireless network adapter when disabled returned all to normal. Appears to be functioning fully except no wifi. Tried to download "Driver Detective",
but did not solve problem. There are a bunch of sites out there claiming to have the correct driver. Tried to re-enable driver and CPU usage and system interrupts reoccurred. Tried to update driver, driver most current per windows. Have not contacted Microsoft
Support yet. Any suggestions on getting the right driver that will not cause CPU usage and system interrupts problems?

Thanks.
