Do I need to reinstall Windows 7 for a new mobo?

Hi,
I'm soon going to be getting a new motherboard and GPU. I already have Win 7 installed to my hard drive, however, I've seen a couple of people saying I will need to reinstall Windows, and others saying that I wont need to. The motherboard uses the same socket as my current CPU. Also, I'll be getting a new processor soon after the upgrade, will I have to reinstall Windows then (Still, its the same socket)?

I know this question has been asked a lot, but I've not been able to find a proper answer yet.

Thanks! :D

  1. I would say yes. I recently swapped out a motherboard with the exact same chipset but different revision on a Server 2012 machine, and had to reinstall because of performance issues.
  2. If they are not same brand MB you are better to reinstall the win7, and call msft (auto phone system ) to active the os, because the MB drivers may cause the problem.
  3. You may.

    It depends on drivers for the motherboard. Is it from the same manufacturer, IE Asus? You could get very lucky and not need to do anything, Windows will find the drivers all by itself.

    Ok, thanks. Luckily, I have an extra copy of Windows 7 that came with my PC. :)
  5. I would suggest reinstalling the OS. With a new motherboard comes a ton of different drivers for the different chipset features, such as onboard USB hubs, Ethernet, sound and Hard Drive controllers. Save yourself the trouble of future blue screens, and reinstall your OS. Later when you upgrade your CPU, you shouldn't have any problems. If you go ahead and try and upgrade without reinstalling your OS, make sure you delete all the drivers that are going to be effected first, and hope you don't miss any or you might have issues.
