On my hard drive I figure it should have at least 15GB of free space, but the amount on it keeps CHANGING currently it is at 4.04MB. It goes up sometimes, it goes down sometimes. This is on my MAIN hard drive, which is something like 70GB. This happened right after a system restore. It's driving me CRAZY because now almost none of my PROGRAMS work right, and I can reinstall them. I asked a tech guy and he said the paging size is fine, and he had me run AVG in safe mode, which showed nothing wrong. I however don't know what to do now.

I really just want to make everything work again. I asked about formatting it and he said not to until we figure out what it is. Any suggestions what to do next?

I really want to use visual basic :-(Go to run type in chkdsk /rWith 70GB HD, you need at least 10.5GB free.
HD space does shrink. It's normal...temporary files, restore points, etc.
What is the pace, of your free space going down?some times it sits idle for 10 minutes or so and then it will change about 6bytes a second, but sometimes it just jumps 200 or 300MB.You're losing 200-300MB in a matter of minutes??yes. when it first started i lost about 9GB at once. Something fishy here.
