If the power suppy was bad, I would think that nothing would turn on. When I get home I will check into it. Thanks for all your help. At least I know where to start now.

I know what the mother board is, but what is an SMPS ?

An iron was plugged into the power strip that was plugged into a ups. The ups got overloaded immediately and the fuse tripped. I pushed it back in and let things cool. Now my computer will not boot....
