I thought I'd take a note of this just in case it comes in handy to anyone else out there.
A couple of weeks ago I installed PCAnywhere 10 on my laptop and when it asked me to reboot, I declined. The next day, after rebooting my computer, I noticed my resolutions were all messed up. It kept trying to show me aspect ratios that didn't match the LCD screen I have. It would also set my resolution to 800x600, or something similarly weak. Whenever I'd try changing it, the computer would crash, saying something like invalid page fault "Page fault in nonpaged area" with "STOP: 0x00000050". The DLL always listed as being implicated was "awvid5.dll". Upon some Google searching, I realized that PCAnywhere had messed my computer's video drivers up. I proceeded to uninstall PCAnywhere, and after rebooting, got my stable operation back.
