I have been trying to locate the cause of common video artifacts that I observe when I play. My card is a Nvidia Geforce GTX 570. Things are very well for a couple of days after a cold start, nevertheless eventually begin introducing artifacts in the games to the point that I cannot examine the screen, and in conclusion I have to turn off, turn off the power, then , establish my PC. After doing that things are very well for another couple of days, nevertheless then repeat the cycle.
So I've been working with the manufacturer of my video card to locate the trouble. I tried all the standard things (memtest86 +, encode times RAM in BIOS, replace the card, the burden of fresh video drivers several times, plus tons of other things). Now I imagine it can be my power supply.
