Motherboard gone???

[Arielladog]

Hey guys,

Here's the deal, this is a friend's computer. Anyway, we would turn the computer on but nothing would happen. Even the power supply fan wouldn't run, so we got a new power supply and installed it. Now, when we turn the switch on the power supply and press the power switch (which is connected to the motherboard), cd-rom ligths come on (but the eject button doesn't work) and the power led light blinks, but the cpu fan doesn't turn on and nothing else happens (you don't hear the hard drive cranking or no sounds and no display). Anyway, when I press the power switch again, the lights just stay on (this may be trivial) and it must be turned off by the switch on the power supply.

Also, in the beginnning, we could smell that the power supply (the original one) was burnt and when we opened it up, it was. So, is the motherboard bad or did we somehow connet the power supply up wrong? Is there a way to tell if the motherboard is bad?

Thanks,

Did you hold the power switch for 5 seconds in the attempt to shut down? Is the system speaker beeping in your attempts to startup? Are there LED's on the motherboard to indicate when power is connected to it? Are you sure the motherboard is not grounded somewhere that it shouldn't be?

Hey and thanks for replying,

Yeah, I tried holding it down for over 10 seconds and it didn't shut down. No sound comes from the system speaker (and it is hooked up). There are no LEDs on the physical motherboard, but the power LED (connected to the motherboard) flashes. I don't know much about grounding the PC and haven't done anythign special to do so.
