I just installed windows 7 today by usb and everything seemed to be fine. The next step was to load up all the drivers from my usb to my desktop but it seems that it has stopped working and can no longer detect my usb. The light of the usb ignites indicating that it is plugged in correctly but isn't recognisable. Furthermore I have no internet on my pc to update these drivers and no CD drive to insert a disk to update my drivers. Anyone have any ideas?
