Motherboard??? no power nothing?

hi i have just brought a faulty emachine 390, 2.3ghz, 512ram, 80gb.
motherboard asrock p4165g socket 478.

when i turn it on no power, no beeps, no fans start, no picture or bios.i dont think theres a light on motherboard.
hard drive and cd drives both work.

have put a new power unit in and new on off switch but still not working.

could it be the motherboard blown? cant see if burned as case on other side cant come off it doesn't smell burnt?

should i pay more money for replacement board (i'll buy the same motherboard)
or if i buy a new board what says that will work?
please help me.

I hate to say it but E-Machines are the disposable computers of the world and prone to high failure rates.

Finding a socket 478 board for that machine will be almost impossible.

As for finding the same board you will need to look on sites like ebay.

Personally I would cut my losses.
