ye its called SR3 about your new motherboard n OS--- if were talkin windows here you probably wasted time reinstalling.... 1. you could have just installed your upgrade windows without reinstalling everything 2. if you replace your MB all you have to do is update the drivers on your HD without reformating it or whatever. 3. you could make your old HD a slave drive and leave it at that or you can make it a slave and then transfer all the stuff from that drive to your new drive
