I'm not messed up anymore, sorry about that. But I have a legit question now

!
I'm currently running Vista Premium but my harddrive is filling up like a gay bar in San Francisco. And for some reason it's running so slow and shitty on my laptop and making my laptop extremely hot and i fear that my laptop will die anytime soon.
What i'm wondering is, should I just reinstall VP or go down to XP or even linux?
I don't really play much PC games or program games anymore, just use a few programs, them being:
*Microsoft Office
*Firefox
*Email
*Guitar Pro
*Photoshop
I mean, sometimes I like to play a round or two of TF2, but I wouldn't die if I couldn't play it.
Help me please, eb!
