My motherboard died, and I had to change it.

Does this mean that i need to reinstall Windows-7 ?
Or can I make it load somehow, and then just install the new board's drivers ?

It should work without reinstalling. I guess you have new motherboard which is different then the one you've had before. Unless there are some big changes there should be no problems for Windows 7 to find changes and update accordingly.

Edit:

In worst case scenario you can fix Windows by starting it up from DVD and choosing repair option (in case anything in bootmgr or boot.ini got problems.

But I would suggest posting exact problems you have (full error message) and checking bios settings.

Ok, but it says something about boot.ini not being right and doesn't load –  Yochai Timmer Mar 10 '11 at 13:34
    
What's the exact message? You sure drives are connected properly and proper boot order is chosen in bios? –  MadBoy Mar 10 '11 at 13:35
    
Says Boot.ini is not correct. Then tries to load from c:\windows ... Says \system32\hal.dll is corrupt or missing –  Yochai Timmer Mar 10 '11 at 13:38
    
Also have anything else changed other then motherboard? Do you have model for old mobo and new mobo at hand? –  MadBoy Mar 10 '11 at 13:39
    
Try the other IDE/SATA port on the motherboard. I think the boot.ini may have the information included at which port to look for the drive. Read this article: support.microsoft.com/kb/102873 –  Darokthar Mar 10 '11 at 13:42

You can boot your computer and then install the new drivers required by your new motherboard.

And you don't need to reinstall Windows 7.

You only need to install any new drivers required by your new motherboard.

The other cases were already handled by the other answers. But let me add one consideration:

Should you have used a TPM-based encryption - such as BitLocker - things would be a bit more complicated. It is possible, though, to create recovery media for this in advance. If you haven't done this, you're out of luck and would also have lost the data on any BitLocker-secured drives.

Good point, but you just need the recovery code, which Windows forces you to save somewhere else or print before it lets you encrypt. –  Mark Sowul Mar 10 '11 at 14:06
