Hey man, you have the exact same issues as I do. I figured out how to fix it hopefully it will work with you too.
It has to do with a conflict with sc2 and more recent nvidia's graphics drivers that is causing the issue, nothing outside the realm of the graphic drivers and sc2 software since every other game you played on your pc has no issues. If you played or looked at the single player of sc2, the in-game cutscenes or interactions have no graphical glitches, lag, and/or blinking screens occur other than in actual gameplay, then you're having the same problems I did.
The one thing I tracked it down to 2 possible things. Nvidia PhysX or Nvidia Display drivers. Since I'm not too sure which one is causing the problems, you'll have to uninstall both, but you need to do a clean install to install an older driver set. You'll need clean sweeper @ www.phyxion.net
, and you may want to reverse any other tweaks everyone suggested so far on your comp so no other problems may arise before beginning the steps.
Step 1. First you go to www.nVidia.com
and look for beta and archived drivers, choose the right gpu you have and the right o/s and dled all the WHQL drivers (except recent one) archiving back to July ##, 2010 right before SC2 came out.
Step 2. The next thing you want to do is completely uninstall both graphic drivers, physx drivers, and if need be nvidia HD audio drivers. If you have to restart just to uninstall the next one from your control panel, then do so if need be.
Step 3. Once everything nVidia is clear, use the clean sweeper program and update the program to the latest one (which should be 2.8.5 if higher then update to that one.) and checkmark everything nVidia, chipsets, display, and physx. and press the clean button in order to find leftover drivers that wasn't completely removed.
Step 4. After it's done restart your comp and install the most recent drivers, and make sure you install DISPLAY DRIVERS ONLY, and nothing else. After the installation and restart, load up SC2 and create a game and see if any problems occur. I recommend using Starjeweled with all A.I. as your benchmark, cuz it is more noticeable on that map than any other (for me it was immediately clear if it wasn't fixed).
Step 5. If the problems are still present, then repeat Step 1-4 with the next older nvidia display drivers on your list, until it is eventually fixed.
I can't say if Nvidia PhysX or the Display drivers itself is causing the problem. If you get the problem fixed, and need the PhysX to play other PC games (or want to see if PhysX is causing the problem), then I'd recommend you use trial and error with the steps I have provided (and install PhysX with your drivers). I kinda did everything else before I considered rolling back my drivers, probably because I didn't have clean sweeper to remove drivers that didn't necessarily uninstall by the one uninstall program provided by nVidia. I even did a clean install of the Windows 7, which didn't help whatsoever, and changing page pool memory did nothing at all. You should be able to play everything on Ultra, without a problem, since I had no problem before until the game started to crap out on me with the more recent drivers.
