I am experiencing a weird degradation of the desktop especially around letters and icons where it appears to shimmer or do the "marching ants" like a photoshop item selection. Browser windows also will breakdown and become mottled or grainy in certain areas like sliders, the URL address line, and text lines. When importing and drawing in, background images will appear at first look like gradients did 17 years ago with all kinds of tiny lines in patterns. This will re-draw and then look normal, but the grainy appearance of other elements will remain. I will also occasionally get a black screen for about 2-3 seconds and then back to normal, with the same grainy appearance in those areas remaining.
I am running Windows XP, SP2, all of my security updates are done, I have run with current updates AdAware, PcCillin 2007, SuperAntiSpyware, RemoveIt Pro, Registry Cleaner and they all seem to come up clean. A friend suggested I update the drivers for the NVIDIA graphics card and I did, but I get the same thing happening.
My feeling is there is something in there that is very elusive, but I am not that experienced at reading the HiJack this logs to know exactly what is what. Anyone have a similar experience? It's driving me crazy!
