Computer won't turn on, no POST.

Hello,

I have a PC that will not turn on.  Yesterday I was at my computer and a lighting storm was coming through (hear me out!).  It was getting bad so I decided to shut down and unplug the PC.  I went to Start > shutdown and waited for it to power down.  After it powered down I unplugged the power strip from the wall; the power strip had both "grounded" lights and "protected" lights on it before I unplugged it.  Once the storm was gone I plugged the PC back in but it would not turn on at all.  There are no fans moving (including the power supply fan).  I tried removing the RAM and re-seating it, removing the power connectors and re-seating them, moving to another outlet in the house.  The only sign of life I see is a small flashing yellow/orange light on the motherboard, it has some letters and number that label it (but I'm not at home right now so i don't know what it is).

I removed the power supply and have it with me at work, I am going to try to get a co-worker to test it with a voltmeter.  How can I tell if this is a motherboard problem or a power supply problem (or something else)?  If the voltmeter reads correctly can i assume that the power supply is working fine, and then what do I do?

I don't work with PC hardware, keep it simple for me if you can!

I am going to try to use this diagram to test it with the voltmeter..... http://img510.imageshack.us/img510/6133/20pin24pinconnectoroe2.jpg (it is a 24 pin connector)
