I built a new desktop about two months ago and I'm running into some graphical artifacts. I was hoping to get some help troubleshooting. As is common with artifacts, I'm only experiencing them in graphically intense games/benchmarks.
So, like I said, I'm getting artifacts. At this point, I'm thinking the cause is either the motherboard or power supply. The motherboard being a possibility simply because I went a little cheap on it and I could imagine it having defects/problems. A lot of the signs point to the power supply, but i don't know if it really adds up. 550 W should be enough for my setup (as far as I know). I was having similar artifacts when I first setup my computer. I noticed that if I unplugged the dvd drive, the artifacts would go away. Suggesting that there was simply a little too much strain on the PSU. Since then I just left the drive unplugged (who uses dvd-drives anymore?). Now the artifacts are back. I suspected that the PSU was the problem again, so to test this, I unplugged the case fans and viola! the artifacts went away. Certainly this suggests that PSU is too blame, but shouldn't 550W be enough for my setup? Additional info power info: I have two harddrives and the the antec 620 water cooler for the cpu. I don't know how much power this cooler draws but maybe its enough to push it over the edge.
Naturally the other possibility is simply that there is something defective with the gfx card.
All in all i'm leaning towards the PSU being the problem but I wanted some second opinions.
highest of seen on temps in 79c. Its a little higher than average for my card but certainly acceptable. I don't think temps are the issue, especially since these artifacts will show up immediately when playing a powerful game, so the temps are still low.
If you PSU is not up to snuff, it will do the same. It isn't clear in your description regarding whether you swapped the Antec 620 into your rig or not. Please clarify. Also plese let us know if you are OCing anything.
