I am facing some issue with Windows XP. I had upgraded to Windows XP from Windows 2000 Pro. After installation the hardware in the system are not installing. I had a cd of my motherboard and I always use this to re-install all the pending drivers. But somehow there is a issue with some hardware which are still marked as unknown devices. I am getting a error that Windows cannot initialize the device driver for this hardware. (Code 37).I tried to remove the hardware which are not working. But nothing worked.
