Startup issues with Windows XP SP2

[Guest]

I recently upgraded my CPU and mainboard. However, doing this caused Windows
XP SP2 to give me errors and not start up. I did a repair installation to fix
the problem, but unfortunately my disk for Windows XP is for build 2600. Now
when Windows starts up it spends about 5 minutes saying "Windows is starting
up..." before I can log in. It also takes a long time to shut down as well. I
tried to access the Windows Update site to see if I could fix the problem
there, but Internet Explorer just crashes when it tries to open it.

Is there any fix to this problem without having to completely reinstall
Windows fresh?

You have to reapply SP2. Use another box to download it and burn.
