Blown Motherboard

[letsdoamazing]

How can you tell if your motherboard is blown? By the capacitors?

How can you tell if your PSU is blown?

Thanks!

it could be both, because sometimes when a PSU blows, it takes the Mobo with it. If you press the power button, does the power supply start?

Nothing at all. No sound, no light, no noise.

This is a desktop, i assume?
well, if it won't start, then that tells me your PSU might be blown.
Do you have another PSU you can try?
or another Motherboard?

This is a Clients Computer, so I don't. But I didn't know if there was a way to test the PSU voltage wise or look for anything. No capacitors are are blown on the MB.

I don't think there's really any other way to test it besides swapping out the PSU and testing.
another thing, might seem like a stupid thing, are you double sure the power button is plugged in all the way?
<edit> just realized what i typed about testing the connection wouldn't work, no way to power it on

Also make sure to pull all your cards when first testing...

A power surge may have tripped the resettable fuse that some PSUs have. Unplug the AC power cable from the computer for a minute or so, and then plug it back in. Sometimes they just need to be reset. My HP at work does it quite a bit, which is why I hardly use it.
