At the moment i am not able to try it with a live medium, so this option will have to wait untill i get a new usb drive.
I tried preload apps but i dont see a difference in loading time.
Havent run the memtest86 yet, will give it a run later today when i get back home

Hello TMG1961,

I know you are familiar with Lite tweaks , the screenshot helps me to write a bit clearer sometimes.
When you get back home can you try the Clean Tasks in Lite Tweaks, zRam, and the Memtest86 to check ram modules. Hope you have a good day.
If it is possible to rule out some hardware issues, accumulated things, it gives a place to move on from.

• Underneath the column named Task (#1 above), some say Clean (example #3a above)
  
• Underneath the column named Grade (#2 above) some say Safe (example #3b above)
  
• Tick to Select all Rows where it says both Clean, and Safe (example Row #3a and #3b above)
  

Are you using zRAM currently ?
If you are not, in Menu>System>Lite Tweaks can you -

• scroll to the bottom of Lite Tweaks
  
• select zRam by ticking it
  
• enable zRam by clicking the Begin button at the bottom right
  

Has zRam improved things in this instance ?
