How do I know if my motherboard was actually replaced??

I don't think it was. Here's the deal. I bought a new computer. 2 weeks later the picture on the screen would "freeze" on me after my computer sat idle for several minutes. My keyboard input in the back also wasn't working. I had to use a keyboard with a USB plug instead. I took it back. Was told it was still covered under manufacturer's warranty. The electronic's store sent it to them. 6 weeks later I get it back and was told they had to replace the motherboard. Well guess what?? It's still freezing!! Plus the keyboard plug is not working. I was also expecting to re-install my programs (I-Tunes, Norton, etc) but they were still there. I figured if they replaced the motherboard they would have had to restor the OS system as well. But that clearly didn't happen. Is there a way to know if the original motherboard is still in there?

Probably not unless you'd marked the old board

or recorded such as the MAC address of an on board NIC and compared the old to the new.

Does it sound as if it was indeed replaced?

That's my other question does it sound to you all as if they did not replace it? It doesn't sound to me as if they did. If they had done so, would my old programs still be there? Would my keyboard plug be working?

Yes, your programs would still be there, and for all intents and purposes you'd never be able to tell by simply using the computer. I do motherboard replacements all the time at work, and so long as you replace it with a more or less identical board, you don't have to reload the OS or anything else.

The easiest way to tell, is if the BIOS revision is reported at boot. If this is different from what you had before, then you know that at the very least they flashed the BIOS to a new revision.

But with name brand computers, they will all have the same basic motherboard, and they can be swapped in and out on a whim. I do this with Dell laptops and desktops all the time. Just did one on Thursday afternoon as a matter of fact. One unfortunate lady had to have me replace the motherboard on her laptop like 5 times before I found a good one from Dell. Never had to reinstall the OS though.

Which is another point. Some motherboards just have design flaws. Dell's Latitude D510 series would be among them. That's the one I had to replace about 5 times before finding a good one. So, it's entirely possible that even AFTER replacing your motherboard, you could still have the same problems. It could also be that it's not a hardware issue, but software.
