Possible driver conflict/s, did you uninstall all drivers from the previous computer.
I then uninstalled the devices (standard enhanced pci to usb host controller) in device manager (2 identical ones with yellow exclamation marks
Did you then go into the control panel and use the detect new hardware wizard, also did you right click on the yellow exclamation marks and if so what were the options or any error message/s given.
Im sure you have looked into error code 37 and so are aware it refers to driver issues, but resolving driver conflicts is not as straight forward as uninstalling and reinstalling drivers, you need to know what you can safely remove ie you will need to know what hardware and software is fitted/installed in the G73-JH, use Belarc Advisor to get this information and also to obtain recommendations on how to resolve any issues http://download.cnet...4-10007277.html
Use Driver Sweeper (W7 version) to remove any left over driver remnants http://downloads.gur...ad.php?det=1655
