Image and sound freezes, need to force-restart 10x a day

Mine was doing the same thing last month - and it happens at the same interval, after 10-11 minutes have passed. Screen freezes, complete lock-up. Ctrl + alt + del does not work - only a cut in power. Found out that I had enough time after starting back up to run restore, and chose a date, and problem went away for a while, then came back. I think I had it isolated to when I updated Avast - after the reset computer after update. Since I stopped, problem has not reoccurred ( knock on wood ).

I was using Chrome back then, and now Firefox (due to another issue with Filmstruck streaming service and adobe not running on Chrome).

Hi all,

Thank you for your feedback and help, truly appreciated.
I ended up testing several browsers, and it appears that FIREFOX is stable. I still can't figure out what the problem was (maybe related to Chrome) and gave up on it while this solution lasts.

I suppose I will need to build a new machine in the coming 12 months anyway.

Thank you!
