My PC is almost identical to yours, just that i have a 3500X Ryzen.
A few months ago i was having driver timeouts like you, then it stopped for a while and started having black screens in games for a few seconds. All that came to mind was the usual like updating drivers updating windows DDU'ing bla bla bla but nothing worked 100%, so as a last resort i just removed the card, cleaned the PCI connector, cleaned the fans, my motheboard, reseated everything, and haven't had any problems since, though im not sure what was the actual cause
