Should I Defrag Every Week??

[BerryCheesecake]

??? Should i defrag my PC every week to keep the sims 3 running "alright". I play the sims 3 EVERYDAY, and i was wondering should i defrag once a week or that isn't really nessecary? I just want to keep it running "alright" like it is now. I play in windowed mode and i don't mind that at all. I don't really know too much about PC care, but i just want to know how often i should defrag.


Thanks! {blush}
