im literally losing my mind here so this is new. Artifacts in 3D apps, and only since updating Sony AW-Q160S (Dell OEM) Firmware from Dell.

Ive already rebooted three times. They dont show up on the BIOS screen as far as i can tell, only once Windows loads. Is that a meainngful clue? Im happy to run tests, i just need to know which ones make sense. i have not overclocked anything on prupose, but i did install a tuning tool a while back. i want to rule out the cheap explanations before i start pricing replacement cards.
