ok i found the problem. when opening up task scheduler i got the popup "Task image is corrupt or has been tampered with User_Feed_Synchronization". I googled this and found that task updates your RSS feeds in IE 7/8. So I went into IE, tools & settings/content and disabled automatically update feeds. I closed out task scheduler and reopen, error message was gone. Ran aida64 and received no errors. Problem solved, thanks!
