A long running issue to which I have been dealing with since I got the computer. I'll start by giving an example as to what it is I am talking about and seeing as SC2 only recently came out, I'll use a screenshot from that...
At random times for no particular reason when in a game that incorporates even a humble amount of stress, my graphics will randomly become askew like you see above. Closing the application and restarting it is enough to fix it but it can come back again but it's so random that I never know when it'll come.
Despite it being a graphics issue I have pretty much debunked my graphics card as the issue as I have tried multiple drivers to no success and I have not only replaced both my SLi 9800GTs with new ones but just yesterday, replaced those with a 460GTX. Regardless of the card, the issue persists, more or less definitively telling me (Despite my bad luck with machines) that the graphics card is perfectly fine and the issue lies elsewhere.
What I have tried:
-Multiple driver updates and variations on my graphics, sound, bios, even chipset. (Haven't touched CPU drivers though)
-Ran a Memtest quite awhile back but it was completely successful after a few dozen passes.
-Ran multiple diagnostics but no issues really arose except for some sound problems but I hesitate to call them issues as the computer was asking me if I heard a song playing, which I didn't.
-A lot of other insignificant things
What I don't think is the problem (But by all means debate):
-I'm becoming increasingly skeptical of it being a software issue despite the BSODs I sometimes get that so often refer to dxg.sys.
-A heat issue (My 9800s ran moderately hot but this 460 runs cooler than those did even when they were idle. The 460 is at about 52C while under stress.
-A power issue. I suck when it comes to power and the like but I have what information comes from the side of my PSU...
Max Combined power on +5v & +3.3v output is 220W
Max Combined power on +12v1 +12v2 +12v3 & +12v4 output is 732W
What I think could be the problem:
-Honestly, I think the built in sound card would be the next place I'd look. It's entirely possible for a poor sound card to interrupt a graphics card and cause something to this degree. However, I'm unsure how to test it. Is there a way to turn off my sound card completely so that I could test it? It's built into my motherboard so I can't exactly remove it.
-Motherboard itself could be faulty
-CPU could be an issue I suppose, perhaps I'll try and find the correct drivers for it to see if that does anything at all.
-Direct X could... somehow be poorly installed. Not sure how but since I didn't build this computer, it's somewhat plausible.
-RAM could be faulty but since the Memtest was completely fine, I'm a bit skeptic of this.
I would greatly appreciate any help or insight into this as I really would love to have a computer that works properly, god knows it's been a long time.
-Random graphic anomalies which can occur at almost anytime while running a game.
-Moderately frequent BSOD. (Whether these occur with this new card of mine I don't know as I have barely had it for 24 hours)
