it's good maintenance to carry out certain tasks on a regular basis to keep your pc running as fast as it used to,the degrading speed is so gradual that you more than likely won't notice it :wink:
check how many icons you have in the right hand side of your task bar, there all programs that are running and slowing it down,do you really need them running? certainly you need your firewall and antivirus,maybe you got messenger but the others,if your not using them stop them running on start up, especially things like realplayer
and office stuff,just because a program you recently installed put them there dos'nt mean you have to let them
