i went to a sketchy website, and i shouldn't have gone, i should have read the signs.. but once it came up many pop up boxes appeared saying 'click OK to continue, or click Cancel to return to this screen" and whenever i hit cancel it just brought up another one, and i couldn't do anything so i clicked OK till they were gone and left the site. i should and just turned off my computer, clicking OK could have been the trigger. but ANYWAY, now, i was using garage band, and it locked up, just constantly skipping, and then the whole computer was constantly clicking and skipping and i had to hold down the mouse key to pull down the menu to shut it down... and when i turn it back one it seems fine.. but its done that twice in the past 5 hours since i visited the site.... any help, comments, ideas, or knowledge would be much appreciated. my AIM screen name is xratrider. thanks.
