Y-You were 100% correct...

I restored default power plan settings and it right back to normal usage.

Alright then, is it possible make the monitor stay on for longer than 10 freaking minutes...

Shoot, I don't have a way of using a CD right now.

Thanks for a link to the ISO download.

To be honest I'm very disheartened that I will have to be reinstalling my OS and programs for a third...

Wow thank you, this seems like a great course of action. Do you happen to have a link to the latest version of Windows 10 ISO with drivers and updates? Or is it here with "Update Now" link:...

Great, I tried the program, and it removed lots of spyware and 1 more malicious piece of malware. Thanks. But sadly it didn't fix the problem. Still getting 100% CPU usage problems.

Thanks! I've...

Thank you for the information...

To update you all, I thought I had it fixed, but it yet again randomly jumped to 100% CPU usage.

Thank you very, very much! I'll attend to this as soon as I can.

I've tried to disable Turboboost/overclocking options in my Bios. That may be another issue, do you think updating my BIOS could potentially fix the issue?

And TairikuOkami, are...

I'm convinced this is some virus MalwareBytes/Defender can't find that's causing the CPU usage issue.

I'm going to try resetting my PC...

Cortana is acting normally.

Hey dalchina,

Thanks, I really have been searching, again, for years for the solution (happened with 8.1 also). I've looked all over and tried every trick I've found, but nothing's worked...
