Will my OS on the hard drive carry over if I swap the processor and motherboard?

Hi guys, I bought myself a terrible prebuilt so I am going to upgrade it with an Intel i5 (from AMD) and an Asus MOBO (from MSI) along with a GTX 960. Will I have to do an OS reinstall and completely wipe the drive or can I just plug and play after the drivers are in?

  1. No. You will need to re-install the OS after switching it over. Make sure to save and write the Windows key down somewhere before switching motherboards.
  2. Will I be able to simply insert the reinstall disk after the first upgrade boot up and treat it as the install disk? The windows key is written on a sticker on the PC so it may be OEM. I just don't want to add another $90 for a new OS disk.

    Actually, it will be fine. You don't need to reinstall OS, but it's recommended, as some drivers will be compatible after switching Mobos.

    You will have to reactivate the OS by entering the key again, though.

    Sorry, as for my earlier post I was thinking about Windows XP.

    So anything from Windows Vista and on you should be fine. But if you run into multiple BSODs then you need to reinstall.
  4. Thanks, I didn't want to buy an OS disk without needing it.

    Actually, you cant have an Asus mobo from M.S.I., the same as you cant have a Suzuki motorcycle from B.M.W.
    Intel i5's are made by Intel, not A.M.D. and the chances of your windows operating system booting to a repairable level after changing from one motherboard chipset to another are about 1 in 12.(Less, switching from intel to a.m.d. or vice versa) You will also need a new code of authority (you will have to pay microsoft again) weather the windows install is repairable or not.
    Sorry about the bad news,there is no way around it without a spare windows licence when dealing with codes of authority sold with prebuilt machines.(The code is linked to the motherboard).


    He means he's switching over to an i5 from an AMD processor, and an ASUS mobo from an MSI motherboard.

    Current: AMD & MSI
    Future: Intel & Asus

    He's also fine, as long as he reinstalls. Drivers will be incompatible if he tries to resume his current copy of Windows, so that's why I'm suggesting a reinstall. You don't need to buy another copy again. Where did you get this info?
  6. I was actually expecting people to misunderstand that when I was typing it. The irony, I can't believe people would think I was that stupid to think that stuff.
  7. You can't reuse an OEM key on most versions of Windows (unless I missed it the OP doesn't state what version he has). So if it's OEM you may well need to buy a new licence.
