Just built a new system. When I turn it on, it will stay on for around 10 seconds and then turn off. The cpu seems to be fine, and ram is set properly. I have a A7N8X Deluxe MB, 2500+ Barton CPU, AeroFlow VA4-C7040 Heatsink/fan, Allied 400 watt power supply. Any suggestions?

I would check to make sure the unit is grounded right, and bad ground can cause a hole lot of problems, and if that does not fix it I would check the other compontent for groud issues. or shorting.

A bad power supply can cause these systoms, but I would have to put my money on a bad ground, or short
