if the motherboard is identical to the old one, no you won't. Xp may not, but you could also get by with a repair install and re-activation. Windows 7 not likely, worst case would be repair/upgrade install.

Best to reinstall, but you don't need to, as long as you have a retail copy of the OS.

If Windows is OEM, then you need a new product key for the OS.

What to do:
  • Uninstall the graphics card drivers before (CCC)
  • Uninstall all the motherboard drivers you can as well.
  • You should make sure the UEFI in the new mother board is set up properly (SATA mode is the same as the old mobo. ex AHCI if old install was AHCI)
  • If you can not boot then pop in the windows installer disk (if you have to) and use start up repair and that should fix it.

I've done it a few times with Windows 7 and I never had an issue.

When you get the new motherboard just plug in the drive, make sure the SATA mode is set right as the old mobo or else you get a BSOD and it should boot up fine. If not try safe mode and uninstall the old drivers. And try again. It should be able to boot fine.

Have you tried troubleshooting to make sure it's really the mb and not say, a bad stick of memory, or monitor?

yea i did some what and gave up. I tried swaping monitors (which did nothing), but didnt swap ram

problems staarted happening after i realized my fan controller wasnt hooked up and my vid card over heating. Games would crash, then eventually nothing would show up on the screen. I swapped gpus to no avail, so im going to try the mobo now

Not always, but I would always recommend it to avoid any performance issues.
