Power supply woes

[Guest]

I have an old 350MHz system which has been cruising along just fine for years. It suddenly quit (refused to be turned on, no lights flash, no beeps, no nothing). Changed out the power supply and it booted right up. Problem solved? NO!

Shut down and tried to restart, everything dead again. The new PS does not work anymore in other PC's either. The fuse is still OK, but just no power.

Already fried 2 PS, any ideas?

Thanks!

What is the model of ur mobo ? Do u have a LED on the mobo ? Does it light on when the PS is connected to the board ?
What are the brand and model of the PS u bought ?
Are u sure ur PS r dead ?
