The task manager is using 13% and it is what is trying to balance everything out so all can get done. You'd need a utility to look at it's internal details and there is probably one or two programs fighting with each other. If it were me I'd stop the browser, in your case FireFox, unplug the cable that connects your PC to the network to see if things drop back to normal levels. One thing that Windows will do is make a PC go bonkers if you are not up to date on patches and updates and you might want to see if any are pending.


Finally you can start Task Manager and go to Details at the menu selection at the top and click it, then highlight what ever has highest CPU use and click on "set affinity" and un select the all CPU's box and click on the last one, like in my case it is #7 since I have 8 cores and they start at "0". One of the few places that numbering starts at "0". Then switch back to the performance screen to see what happens.

Last of all check hard drive storage to see if the drive(s) is full and why.

Please let us know what happens. Good luck
