well,if it aint hackers sirloin,,it could be your vidcard or your windows me updater<~~i got windows ME too,,and i have zonealarm firewall,,and all the time your windows is tring to reach out and update every time you sign online,,,so if you can shut down the windows updater in msconfig it mite help,,because i can tell when mine is tring to update because my games started to run like crap everytime it was tring to update or scan,,i had to turn everything off,,stupid windows updater ends up messing your computer up anyways then the problems it fixes,,lol
but allso i would check out the hard drive and vidcard,,sounds like vidcard if it drops to 8 fps,,what kinda card you runing? and how much memory?
