Anyway to tell if mobo is damaged from intalling bad cpu and powering on?

OK, here's what happened: My system shut down once and wouldnt turn back on. I smelled something burnt, and thought the cpu may have fried. I took it to my friends cpu and installed it in his board which was able to run the cpu that I had (he was running the same as mine). I wanted to insert the cpu in his board and turn it on to see if it boots, that way i'd know if it was my cpu that was fried or my motherboad. Well, after i installed it in and booted, it didnt turn on and apparently I think his mobo may have been fried from putting my (unknown at the time) bad cpu in the slot. Now what I'm wondering is, can this actually happen, or did something else happen I'm not ware of, and is there a way to "test" the motherboard yourself to see if it's functional or not?
