I built this computer about 5 months ago and no problems. For some reason about a month ago, my computer randomly shutdown on its own. At the time I didnt think to much about it because it didnt happen again for a while. But now it seems to be getting more and more frequent. It seems to only happen when I am running heavy loads (a lot of time with many firefox windows, limewire, a few minor progs and mabey diablo). It will also do it if I close all things and just run Americas Army, and then when I alt-tab out to desktop then go back into the running game it does it.
I was thinking ram at first, but I have 1gig and it doesnt seem to be getting close to maxing it out.
I also thought mabey overheating, but the bootup temps seem fine from 38-40 range.
As im typing this I sort of think videocard because of the americas army thing (yet i can do the exact same thing with warcraft III and no problem).
