I'm having a problem with coloured squares an my monitors and my PC turning off. I had a similar problem a month ago I changed my Gcard drivers (to older version) gave it a bit of a clean and it was fine.
Now that doesn't seem to solve it. Worryingly those artifacts even appear when booting up in the form of white squares. If I remove the Graphics card and just use the GPU on my cpu everything seems stable.
Could it be a bad Graphics card, PSU going bad, both, or something else? Any advice would be greatly appreciated.
460 gtx (on 2013 drivers as seem the most stable)
