I use CCleaner on Start Up and I have done for many years.For a HDD to perform as it should it's best to try and leave at least 25% free. Have you tried running something like Ccleaner?

Also why not place some files in the cloud? Microsoft's Skydrive allows for 7.5GB of online storage for free:

You could also try burning some files to DVD or buy an external Hard drive
Also a good tool to find out what is taking space visually is WinDirStat, available at http://www.windirstat.info
Having a cleaner will not solve your problem. Yes, it will clear up some space, but seeing how you only got 1.5gb left, it's not going to clear more than a couple gb, if that. Go out and buy another hard drive.
Lets see...HDD 1 TB size avg price $70.

New computer, desktop retail, lets say from walmart....avg price for avg desktop, roughly $500

Sorry didn't realise they were so cheap. Can you recommend one for my msi laptop that currently has a 233GB Hitachi HTS545025B9A300 SATA Hard Drive and I live in the UK?
Cheers
Don't know if this will help, or if you have the funds.
I have Windows-7 running on a 120-gig SSD drive. Makes the OS rock..! I have a second drive, a 2-TiB sata2 hard-drive for my storage.
BUT... if you go this way, and many have. You really ought to put the System Temp, Temp, pagefile.sys on another drive. It will extend the life of the SSD drive.
You know on the boot-up, how you get the four swirly colours.... and then the blue-ish "welcome screen".
Since going to an SSD drive, I don't even see the blue-ish welcome screen...!
