Motherboard Upgrade Help

[WrigleyPlaysPC]

I currently have a windows 7 OEM build that has an MSI a75ma-e35 motherboard and an Athlon 2 x4 750k. I plan on upgrading from the fm2 motherboard to a am3+ board and a 6350. Will I have to reinstall windows? Do I need to wipe my hard drive and ssd? I'm really confused. Please help!

You cannot switch your motherboard without purchasing a new OEM copy of Windows.

Can I call Microsoft and get the activation code reactivated?

The OEM Win7 license is keyed to your existing motherboard.
