You shouldn't be running into a problem where Win2k deteriorates that badly in a matter of months without you installing anything new or constantly tweaking. Shouldn't be a swap file problem either with 512MB RAM. I have a machine that I installed win2k on it when it first came out, and have only had to reimage it once. The reimage took 5 minutes
. It's so nice to make an image instead of reinstalling the thing and drivers from scratch. this is providing you use the OS properly, of course. I've seen people kill it in less than 7 months - but that was an extreme case of non-stop mp3, mpg, etc. downloading and installing every Gator Companion, Bonzai Buddy and Webshots pop-up ad inspired program. But it's an excellent to clear temp files and do a Defrag.
Just curious - how hot does it get in the cab? Do you have any fans blowing air out?
And remember - If it's not worth your time troubleshooting it, you may as well do a fresh install.
