thanks begeegs, i have had a look and the only three things with high usage are ...semonkey which is my browser but it doesn't seem to use much and pluin-container.exe which seem to be needed for firfox...it uses a lot sometimes 100%...everything else is 00-10 ....except system idle process 00- 70 approx
Unfortunately, if it one process that is using it, you can do a couple of things - increase your paging file - which is dependent upon how much free space you have on your drive and how much RAM you have as well.
It probably will only help a little bit. Whatever you are using in Firefox is destroying the processor.
I would suggest on laying off the dodgy videos 😆😉
