  1. I think that the system files will be stored on the HDD or SSD so I don't think you need to get a new copy
  2. If it doesn't boot with the new motherboard then you will probably need a re install but you will have to reactivate with Microsoft either way. You don't have to buy another windows, just reactivate and if you haven't done it allot of times it should reactivate
  3. For a motherboard change, a reinstall is usually advised. It might boot with the new hardware, it might not.

    And it will almost certainly ask for reactivation.

    If your motherboard chipset doesn't change to much then you should be fine. (Intel to Intel, or AMD to AMD) If you have an OEM version of windows it should complain about being in a new system. You should buy a new copy at that point.

    I bought new motherboard because i wanted to replace my old AMD Athlon 255 CPU to AMD FX6350. And old chipset is AM3 and new one will be AM3+

    Try it and see if it boots (but backup first). If it does then just reactivate Windows

    okay thanks for that. But i don't have my new CPU and motherboard yet i still have to wait 4 days or less.
  8. It should work fine. The drivers that matter should be nearly identical. Might want to double check your IDE/AHCI settings first.

    IDE/ACHI? i never heard of it. What is this. And how do i do that
  10. Check the bios settings. IDE vs ACHI is the method windows uses to access the hdds. If windows is set to use IDE on the old board, and the new one is set for ACHI, then it won't boot. It's a setting in the bios, you need to check the hdd settings.

    Okay but problem is i already ordered it and i just have bad feeling that i will need to reinstall windows. Because my motherboard is old. I remember i got that in 2010 just with Geforce 210 video card and very old motherboard with AM3 support and installed AMD Athlon 255 CPU. I added more rams and new video card GTX650 1gb OC version. Now i am waiting for my new CPU and new motherboard AM3+ to arrive. It's like i am trying to rebuild my PC.
  12. Age shouldn't matter. I mention because your old board might be setup as IDE, and the one might be setup as AHCI instead. I had this problem when I went from my P55 board to my current Z77 board. I was running in IDE mode, and had to change the SATA controller from AHCI to IDE. If you don't, it will blue screen on you. If you figure out what you are using now, you can check when the new board gets here.

    Motherboard name i guess Asus M4N64BT2 V2. I can see there is written on my old motherboard EPU i don't know what does it mean And i still have no idea how to check your IDE or ACHI whatever. I don't wanna remove my old mother board yet.
  14. You don't remove your board. It's a setting in the bios. I have no idea where. You'll have to check yourself. Probably under the advanced settings.
