I Need DESPERATE Help with my laptop.!!!

[MainEvent24]

I have a 2 year old HP Pavilion ze2000 and a 60GB Hard Drive, and 2 Gigs of virtual Memory, XP I am contemplating whether or not i want to restore my complete system and clear my hard drive. Here is the story. I bought The Sims 2 Double Deluxe at walmart. When i Installed it and tried to play the game it said: Please insert the original disc instead of a backup (1000). Which is complete junk.

After calling technical support i was able to play the game once because of deleting all my processes in windows task manager. Woke up yesterday and COULD NOT play it. Thank you ea, you were wonderful help. Same message i had gotten before. I didnt want to take the game back because i thought there was some other way to run the game. after reading 100 forums I learned that there was emulator software that i could download, so i downloaded everything i could in hopes i could play my darn game! but no luck now i have a full hard drive and no way to play the sims 2 double deluxe, thanks again EA.

Anyway, i made a list of all programs i need to install after erasing my entire hard drive, but found that I have MICROSOFT OFFICE 2007. and said OMG i dont want to clear my hard drive. I also have other drivers/like my internet provider that i want to keep. And most of these things wont fit on a CD-R or Jump Drive. After my head exploded i looked at my C: Drive, and found something really weird: (60GB HDD) 60 Gig hard drive- C:/Documents and settings=17GB- and C:/Program Files=9.50GB and there are about 3 extra files in that folder that equal a small amount of MB's, so i would say thats another 3 or 4 gigs at the most. Im not a Mathematician or anything, but that DOES NOT equal 60 Gigabits. Where did my space go. Ive ran Disk Defragmenters, and disc cleanups. I dont know what to do. i want to erase my hard drive and completely start over like my computer is brand new. i do have cookies and saved passwords, and drivers that would be a pain to install again. As well as Microsoft office 07, that a friend let me borrow.

1. Uninstall all crap software.

2. Download and run CCleaner.

3. Disable, then re-enable System Restore to clear out all old restore points.

See where you stand.
