About six months ago i upgraded from a gtx 460 to a HD 7950, and while my gaming performance in every way has gotten better, however occasionally in non-gaming applications (palemoon, firefox subset normal desktop) i will very get a millisecond hiccup in my image, where it will utterly distort and go away, and i'm unsure as to the cause other than it must be related to the gpu drivers by my guess.

I have it connected via a DVI to HDMI cable setup due to my display having the EDID mismatch issue, and my temperatures are fine (68C max in a overmodded skyrim test, crysis, etc., average 37C) and this did not happen on my GTX 460.

Normally i'd just ignore it, as i thought it was maybe the horrible drivers issue i've heard about when it came to amd cards, but 2 days ago, it froze on a distortion, so now i am starting to worry about it.

Any help is much appreciated.

I cant stress this enough, make sure all of your old nvidia drivers are cleaned out. then clean out all of your AMD drivers and install catalyst 13.9. Small chance you could have bad or corrupt vram on your card.
Make sure all java is updated because i've had similar problems in browsers that were a java issue. I personally would do a clean windows install and make sure everything is up to date and if it continues, the problem is elsewhere.

Okay, I'm no AMD user and you may get some AMD users replying, but if this happened to me I'd suspect the drivers. If you had no problems with the nvidia card/driver combination, then it has to be an AMD issue.
It may be helpful to tell us what monitor you're using and the model of 7950 card.

Thank you both for your assistance.
I have strong doubts it's the GPU's Vram, games do not seem to have this problem as far as i can tell, only desktop applications, usually the web browser.

I will try and update java, i am not 100% against a reinstall, but it would be extremely problematic so i'd rather wait on that if possible.

As for nvidia drivers, i'm 95% sure i got rid of all of them, however do you know how i can check to be sure?

As for the amd drivers, it has continued on from multiple CCC installs so i do not believe it is due to CCC.
