Do you have a spare hard drive? Probably the best thing to do would be to shut down your Windows whatever system, swap in the spare drive, and do a clean install of Windows 7. When you're done, just swap the old drive back in and everything's back to the way it was.
The only issue with an old P4 is that if the problem is 64-bit specific, you'd only be able to install the 32-bit version on it.
