Seemingly randomly, my system begins stuttering when doing basic things. It's most noticeable when pulling-up Windows 7's taskbar (it's set to auto-hide) and viewing Winamp's spectrum analyzer visualization thing when something is playing, both of which become very choppy in animation. Nothing in Task Manager seems to indicate anything hogging the CPU however. Oddly enough, starting Task Manager or opening Windows 7's Control Panel instantly remedies the problem...
I usually only have Firefox, Winamp, and maybe some other insignificant application running when this occurs. No background programs at all. I run a very well maintained system and all of my drivers
and software are up-to-date, but this has me stumped.
I know this is a bit vague, but does anyone have any ideas?
