Knoppix recently started freezing randomly when I'm on the computer. It USUALLY happens after I click a link. This happens in Mozilla, Firefox and even Konqueror.

At first, I thought it was my configuration, as when I tried to load it at the next boot. I had a long list of error messages saying "free blocks count corrupted for block group 16" So I tried not loading it, it still froze afterwards. Then I tried not loading my persistent home, and it still froze afterwards too, right after I click a link. I tried loading it from my HD through a poor man's install and it froze too in the same circumstances. Right now, Knoppix is loaded from the CD, no cheatcodes of any kind. I'll see if it freezes too.

There's no error message whatsoever, afterwards and I've tried searching the forums and found nothing. It just freezes, and my mouse and keyboard is unusable.

My specs are as follows

P4 1.6 ghz
512 MB RAM
20 gig HD in FAT32 (just one partition)
SBLive! Sound card
Geforce 2 MX400.

Any ideas on what's going on?
