Problem it slowed my pc down, am i running to much stuff?? any recommendation’s of what i need to add or take away?? ;D thank’s ekamb1

my pc is windows sp3 and 32 bit i think

I doubt whether teatimer contributes anything useful, so maybe you should try turning it off to see if that makes a difference.
