6990 2d artifacts?

I've owned my 6990 since early April, never OC'd past the BIOS switch on the card. Recently(1 month or so) I've been seeing a lot of strange dots on my screen, but never in a game or while playing something in VLC, etc. My machine has been giving me BSODs recently, but it seems to only be caused by my SSD(known issue.) Again, I've NEVER had an issue with the card while playing a game. It runs everything I throw at it like a champ and never complains, even when running full eyefinity with AA. I have been getting what appear to be driver crashes recently, where my desktop looks low quality and if I launch a game I can't change the resolution, but I have never seen a notice of any driver crash.

There are only a few dots in this screenshot, and they happen to be purple.
Idle temps of 47C on both cores atm, never seen a temp that looks high. Fan acts as it should, scaling seems good. I'm thinking VRAM, is there any real way to test that?
 
Since you can capture the artifacts with a screenshot it must be graphics related, not the cable or display, so it's either a bad driver (seems unlikely if you suddenly have problems) or a faulty card.
 
I have none with my 6990. Works flawlessly.

6990 WINS! FLAWLESS VICTORY!
 
It may have something to do with the ULPS settings?

I am throwing that out, but I can't recall how to diagnose it on this card.

Maybe look at increasing the power slider in the Overdrive portion?
Try a different driver set?

Honestly, if it still kicks butt in 3D that wouldn't bother me too much, but it may be time to consider RMA if it does.

Sometimes it doesn't bother me much at all. Right now I can only see a few dots. But it changes rapidly and can get pretty obnoxious. I really don't understand what could be faulty on the card that would make it misbehave in 2D but still dominate anything 3D.
 
I'm honestly having a hard time believing that the card has some sort of hardware defect after my recent attempt at OCing it. 975/1450 Furmark stable with no extra voltage! I don't have RMA as a good option as all my extra parts are at my parents house and it would be hard to get my old 4870 to use as a stand-in.
 
What is the best way to do that? I seem to remember doing that on my 5870 due to DisplayPort issues, but it's been a good while.
 
Hmm not sure as I've never had to do it, use of a second monitor will normally do it automatically, so this may not apply to you.

As I recall it's a registry edit.

All I'd say is google it, I read about it sometime ago and the fix was pretty simple.
 
Somehow I've fixed it. I pushed my core clock up to 1000 and got a crash. When I booted up again, no dots. I haven't seen a dot since then.

This is driving me mad.

EDIT - AND THEY RETURN!
