Uh.... registry dumps can do so as well ... also programs like CPUz/Everest/PCWizard etc ... in the case that you have an OEM, if you dig deep enough you can find info from the makerUnfortunately mate no you can't you will have to open it up and then get the serial number on the motherboard and the make, then go on the make's website and look for the mobo with the serial number.
