I have blown 2 powersupplys, at first i though it was the MB so i switched to a new identical MB, both boards have blown 1 power supply. 350W and a 400W. The 350W lasted about a week, and the 400W on the second MB lasted about 15 minutes, There are many other computers in the house that have never had any problems simmiler to this. Any thoughs or sugestions on what may be going wrong?
