Hello computer professionals! The aforementioned pc running Windows 7 recently spontaneously began to NOT recognize the keyboard. I have tried it on other windows pc's with no problem. It is getting power and i have also tried it in all my other usb ports. I have also ran Dells diagnostic support program to no avail. It works fine until Windows boots up. I have restored back to an earlier system restore point and unonstalled it with success until Windows updates the driver. I cannot find any setting in the BIOS for the keyboard. I have also disabled automatic driver updates from Windows but without fail when Windows boots it replaces the functioning driver with the non-functioning one. Please advise and thank you in advance!
