New CPU/mobo needs fresh OS install?

Hello all,

I'm curious about a recent upgrade.

I upgraded my CPU/mobo from a Phenom II 965 BE Quad on Asus M4A87TD Evo to an FX 8350 on Asus M5A99FX Pro 2.0...

Everything I've read online basically says I would need to reinstall a fresh OS claiming that the different SB chipset would cause it not to boot.

Well, it boots. It self installed drivers. Everything "SEEMS" fine.

So... Should I count myself lucky? Will there be any problems/conflicts that may surface later? Should I still do a fresh OS install regardless? I would really rather not if I don't have to.

Current System:
Cooler Master HAF 922
AMD FX-8350
Asus M5A99FX Pro 2.0
Corsair HX750
G. Skill DDR3-2133 4x4G
Samsung 840 Series SSD
Gigabyte GTX760 OC 4G
Windows 7 Home 64bit

  1. It is recommended to do a fresh install but repair and drivers for the new hardware is fine as well. If it all works no worries!
  2. I wouldn't mess with it if I didn't have to. sometimes you get lucky. if all your data was saved and you have no problems and that's what you want......... don't sweat it.

    now go to windows update. maybe things will go fine or you will have to validate........... or you'll have to reformat. back up what you need or want beforehand.

    You are good.
    Once windows boots, you can install any chipset drivers from your new mobo cd.
    If you change platforms that are similar enough to allow windows to boot consider yourself a bit lucky.
    Normally, intel to intel works, and in this case, amd to amd works. It is switching that will usually not work.

    With a motherboard change, you will need to activate windows within 30 days.
    If your windows was retail or upgrade, you will have no problem.
    If it was oem, you might need a new copy of windows. But... MS seems to be very lenient about reactivating with oem if you assure them that your copy is not used elsewhere.
