lol same thing happened to me your BIOS observation is a good clue. If artifacts appear only after Windows loads the driver, but not in BIOS or in Safe Mode (which uses the Microsoft Basic Display Adapter), that leans towards…

Reset any overclock or undervolt, especially memory clock. Artifacts that look like small colored blocks are often VRAM instability, and a drievr update can change memory behavior enough to tip a marginal OC over.
