So I've been a sysadmin for many years, dealing with mostly Linux servers, but I've only been using Linux exclusivley as a desktop for about 4....
We all know that windows machines tend to bog down and crap out, it's only a matter of time. And most of us, being computer folk, know how to clean it up and get it running nice and shiny-like again. Myself included. What I've never had to deal with (not having to deal with user applications being installed in the server world) is a Linux machine starting to act this way. Now, I'll give it that I've had this system running for 4 years, much longer than a Windows machine would last given heavy day to day use with games, web, email etc. - But, now it's starting to bog down, and I don't know where to begin cleaning it up. I have plenty of disk space, my RAM is sufficient..
Any ideas where to start cleaning up and getting things running smoothly again?
