HDD space decreases to zero

[kidsquid]

Hey fellas.

Thank you for reading my post.

I'm baffled, no other way to describbe it. When I turn my computer on I have 145GB of free space on my C: Drive (partition) As the hours go by, this slowly decreases until it reaches 0GB.
When I restart, its back to 145GB.
I've deleted all programs I thought might be the culprit, the only software I could think was doing this was Peer Guardian, or maybe Avira, making massive log files?

I have scanned abasloutely everything with Avira, AVG, Hijack This, Spybot, and have checked each process against the online database, and nothing seems out of place.

When I go into C: and try and determine where the space is being eaten, all folders properties sizes add up to around 50GB, making this impossible.

TreeSize doesn't help either.

If anyone can help, I'd be so, so grateful

Matt

Found the probem. I used BootVis the other week, and hadn't told it to STOP logging. I opened BootVis and turned off the log tracking, and its now all good.
It didnt half worry me though!
