Re: New build issues
1. Can not understand anything. Did you just swap those things (mobo, cpu, ram) on the same motherboard? And You did nothing else? Not even the BIOS did update (of course, if such an exchange is at all possible - I very much doubt it is possible, because details, what You gave let very deeply doubt, that it is possible).
2. The second thing You said - there was Windows 7 installed and You want to upgrade? It should be possible without any problems with this(those) processor(s). And if there was before installed and activated Windows 7 then You don't need to buy any key, this upgrade is free for all Windows 7 and Windows 8 users.
