Help needed please for hot slow CF-19, Mk6

Hello All, hope your all well. I need a little help with my Mk6, over the last few weeks it seems to have slowed and is getting hot on the right hand side of the palmrest.
I dont know if its slowed because it hot and its throttling back to save it getting hotter or its got another problem.
Its used to be lightning fast as its fitted with 8gb and a SSD but now when I click on an icon its taking a good 30 - 45 sec's before the program opens and when open it runs slow

What can I check please

Thanks

 

Thanks, that wouldnt be easy for me, I'd need step by step for that.
Ive just looked and at idle its using 49% CPU and 55% physical mem, is that to much at idle ?

Thanks

 

Ive just checked my Mk4, its basically the same setup, 8Gb with SDD and at idle 0% CPU and 29% physical mem, could that be the problem, where would I look to see whats eating the CPU on the Mk6 ?

 

Download a live linux iso. Burn to usb and try it.

 

What version of Windows are you running? I know XP has an issue where the updater can tie up 50% CPU, essentially one complete core on a 2 core processor.
Have you run Malwarebytes and/or KVRT? Maybe a virus or Trojan, or Bitcoin miner got on it somehow.

 

Im running w7 on both, Im just running a scan now, its not even a 3rd of the way through and its says there's 191 infected files, i'll have to wait till the end to see if they're ALL bad files or the AV has picked up loads that are not.
It only goes on the internet for updates so no idea where all the infected files have come from

Ive got the bottom of with a 3 inch fan cooling it as its on charge as well

 

I'm not sure about CF-19's personally, but if the bottom is designed anything like how the CF-30 is, removing the bottom cover will mean you're taking the heatsink and thermal pad off of the CPU. Blowing a fan on a CPU with no heatsink isn't going to be very effective at cooling it, and may actually make things worse.
