Hard Drive Shows Full But Isn't

[Guest]

I have a new computer running on Vista Home Premium. There is a 232 GB hard
drive which shows only 75 MB of free space. I have about 10 GB of programs
and data on the hard drive. I have checked hidden files, deleted trash, and
cleaned up the hard drive.

Last month I installed an online game, Everquest, and I leave the game on
24/7. Could that be part of the cause? Does VISTA have a problem with
rewriting data to the hard drive? I used to leave the same game on running
Windows 2000 and have not had a problem with the computer over the past six
years.

Since yesterday, with the computer turned off, my free memory is down to 65 MB.

Sheesh!
