About a month ago i noticed my 2t hard drive was almost full and the computer was getting slower and slower... on boot and in use.
i started with a timeshift. That did nothing to help. Then i moved all my video to a external HDD and deleted from the computer ordered new ram and flowed up with anther timeshift.
Thats when i started to need the boot USB

My video file shows its empty but [Disks] shows no more space and [system monitor] is telling me that two of my CPU cores are running at 100%+- the others at 20%+- .
Did a s.m.a.r.t. on the drive and it tested ok.
Then i got the RAM and started playing with it and it got worse!
The usb sitting on a big magnet for 18+-hr did not help.
i did get the computer booted BUT it took about 45min and now it sees my 2t SATA as IDE!?!?
LOL time to do 41 updates.
