ive been having the most trouble with my computer latley. my startup/task bar keeps freezing up. if like a new icon of a program pops up the whole thing flashes and it seems like theres a chance it will freeze up. ive tried alot of things. i have no clue of what to do. i need to install windows me oveer the top to see if im missing any files. someone told me it was something eating up my memory or something. im just not realy sure.
