Hello Technibble forums! I have a customer with an Acer Aspire 5517 laptop running Windows 7. She has a bad motherboard. I've never replaced a laptop motherboard before but I'm quite confident I can do it no problem. The only thing is, this is just an OEM version of Win7 and so I can't do a clean install of Windows after the motherboard swap. So what do I do: do I swap the motherboard and then run a repair install from my retail Windows 7 disc, and then also run that program on UBCD4WIN.. what was it... that tool that resets something in the registry...? And then also, I'd imagine I'm going to need to call Microsoft and tell them that I changed the motherboard and hopefully they'll activate it?
