Sorry for the odd subject heading, but it was the only way to explain my problem. When I turn on my computer let's say I have 8gigs free. By the end of the day I will only have like 1gig free. Something in XP is eating my memory. However, when I reboot my computer, my memory reappears--in other words I have the 8 gigs free again. Anybody got any ideas how to fix this or even what the problem could be? By the way: Running XP Home, 1.7Ghz, 40gig HD--and I tried running CHKSDSK or however it is spelled but it hangs at the end (maybe this is the problem?) and does not reboot my computer when finished. Thanks dudes!
