Right click on the my computer icon,choose properties, hardware profiles, then copy and rename it to original configuration 1.
In the new profile manually set IRQs so none are shared by hardware componets then reboot, when your booting windows will stop and ask which profile you wish to use for start up.
Choose the one you created and then test for problems with the new configuration, if all is well you can then delete the original profile and rename the one you created as original configuration - otherwise you will have to choose a profile everytime you reboot.
