System Looses functionality after being on for 4+ hours, Event Viewer has multiple errors listed.

I reinstalled windows xp MCE about 2 weeks ago, and since then, have been having tons of problems with my system. If I go to sleep with it on and only running firefox and thunderbird, when I wake up, both are no longer responding, and the system no longer has internet.  If i go start-shut down, then the same options appear as if i clicked on log off. This has happend for many nights in a row, so i know that I am not clicking on the wrong button.  After I do a hard shutdown, then turn the computer back on, it works fine again, with only thunderbird needing to rebuild its email database.  I have all of the updates from windows, so I am not sure what is causing the problems.  Below I have copied all of the errors I have recieved in the past day from within the Even Viewer.  Thanks for your help.
