Google is your friend, but only up to a point.
I spent a happy evening earlier in the week fixing the PC of a very dear and somewhat frail clergy lady. A virus in an e-mail from some dastardly spammer had got past AVG (not working, because they'd updated and she hadn't) and shredded most of her machine. We got her document folder and e-mail back, and then reinstalled Windows XP - but the driver disk for her mobo was gone (it was undoubtedly in her study along with a medium-sized library and much else, but we didn't have weeks to search for it).
Result = no sound, and much else of the motherboard stuff not available either. XP didn't know what to install, and couldn't tell what the devices were. "PCI Device" mostly, with nothing more in the details tab in Device Manager.
She can write and print stuff, she can get her e-mail and browse the web, and her scanner will scan, copy, and fax.
When I have a day to spare, I'll see if Everest will tell me the Mobo type and from that Google will tell me the drivers - maybe.
