Currently I am running a Althlon 64 3200+ , 2G 3200 DDR, and a Gforce 6800XT 256MB that is running XP MCE. Also, I have a 400W PSU with one optical drive and two case fans. Now, when I orignally installed MCE, everything was running smoothly, up until recently, when my computer will just randomly restarts. Usually when I am running certain programs, Firefox 2.0 for example, and the Ciy of Heroes game client. I first though it may have been some sort of heat issue, so I purchased a new cpu fan, but I still have the same problem.Then I tried swapping both sets of RAM chips, but to no avail. Now, last night and the night before I left the entire computer running, and it never restarted while I was running IE7. But, as soon as I started to run the CoH Client for about 20 minutes, *bam*. And sometimes what may happen is I will not be able to restart the computer for a few minutes, but usually it will just restart on its own. Is it at all possible that it is a PSU related issue, by it drawing a bit too much power, thus it restarting when I am trying to start up programs that require a bit more power? Or maybe that all my RAM chips or my RAM slots are bad? My only other problem is that the sticks of ram that I have now are the only sticks that I have so I really can't check if it is all of them. Also, is there some sort of diagnostic program when I could check?
I thank you in advance.
