What it looks like, it's part hardware and part software, but hoping I can see what can be done with the hardware that doesn't require replacing. The cost and age the machine is not worth it. I have considered taking it to a repair place to have a checkup and cleaning service (of the inside of the chassis).
I've done all the basic steps to check and perform for slow computer issues. Updated, running performance diagnosis/disk cleanup tools, running second opinion scanners (AV is always actively running).
I didn't find the right solution from the internet.
