May have solved that frequent crashing problem.
My desktop PC is a first generation Dell i7 purchased back in 2009 with 8 GBs of RAM. It still runs great. In fact since putting in all SSDs it runs better now than when it was new!
Anyways I do push it now. Run a few browsers besides Opera and have sometimes 30 tabs open, or more, when running them. My System Monitor shows most of the 8 Gigs of RAM used and some had to go into the Swap file for help. Well Opera acts a bit quirky then, stalls has trouble keeping up and then crashes a lot. Firefox, Brave and Vivaldi run more stable by comparison while doing this and never crashed.
So since RAM is cheap, got and installed and now have 16 GBs of RAM. PC recognized it in both Linux and Windows with no problem. Noted a marked improvement in PC performance overall. And so far Opera has not crashed once and runs better than before. Maybe that was the issue all along when pushing PC like I have.
