[mdlug] computer shutting down

[Robert Adkins]

    I was having a similar problem with a system of my own.

    It turned out that one of the chips on the mainboard was 
overheating. I believe that it is the Southbridge chip as it tended to 
happen mostly when performing hard drive intensive activities. It took 
me a significant amount of time to discover that the Southbridge was the 
culprit only because it seemed like the CPU and Graphics card were both 
part of the problem.

  If it is one of those chips, you should be able to locate an 
aftermarket heatsink solution to install onto the mainboard.

  Personally, I would replace the mainboard, (especially since you state 
there are other issues) but that could prove to be very expensive, as 
was in my case since AMD changed from the 939 socket to the AM2 socket 
and all the manufacturers of mainboards followed suit.
