I'm not sure about the quality part, but my comp freezes up and says no more memory alot. When that happens I do a clean up of the temporary files and such. Either with just the control panels internet options or if it's real bad I do a disc cleanup of all the old files and that seems to help. Not sure if that's going to help you or not, but I thought I'd toss out the idea anyway if you haven't already tried it. Good luck!
