Motherboard Type

I have to find a manual to my motherboard, but I don't know what motherboard I have.. Shouldn't it be printed on the board.. Or is there somwhere that it would tell me in the boot up?

Thanks for you're help....

First check the pcb itself most of the time it has a name one it, it's kind of hard to find so really search for it, then try cpu-z it sometimes tells what mobo you have, but it's best to check to mobo to be sure.
