I assume you've run Disk First Aid.

I'd suspect loose RAM or VRAM.  Turn the machine on, make sure you're
not doing anything important, and pick it up and shake it.  Does that
trigger the problem ?

A number of other problems you report seem to be hardware-related, too.
If you have any confidence with hardware, back up your Macintosh, open
up the case and have a fiddle inside.  If anything looks loose or
poorly-seated, unplug it and plug it back in again.
