Buzioid,
I am guessing the BSOD is something like "Inaccessible boot device"?
A repair install XP works great! To be absolutely safe, back up the important stuff. But if you do the repair install correctly, you shouldn't lose any of your settings. More importantly, all your files will still be the same.
The only real difference you will see is that all the Windows system specific files will be reverted to the original ones. (For example, any hotfixes will need to be re-applied). The other benefit (which is why you would do this), is that it re-enumerates all the hardware on the system.
A great website to help you repair install can be found
here. Scroll down to the "How to repair install" section, and follow those instructions word for word!
