If it runs OK in safe mode, but plays up in "normal" mode, I'd go for the "one driver at a time" test to see what's upsetting it.
Alternatively, do a "reinstall repair" where you start as if you meant to install the operating system over again (ie not the "repair console"). Soon after the offer of the repair console, it will tell you it's found an existing installation and do you want it to attempt to fix that. You do.
Obviously, back up your important stuff to an external drive before you do that (use safe Mode).
