Input devices (mouse and Keyboard) not working on Inspiron Desktop
I have a three year old inspron desktop running updated windows 8 Suddenly NONE of the input devices are working. I've tried several different wireless mice, and I've tried both a wired and wireless keyboard. NOTHING. I've tried unhooking all, rebooting, then hooking them back up... still nothing. Tried rebooting with them installed. Tried switching USB ports. ARRRGGGHHH. Since I have no keyboard I can't do safe start (don't even know if that works with windows8 ).
I do have a "repair disk" that I created when the compter was new.... tried rebooting with it in the drive.... didn't do anything other than restart the computer with the same non-functioning input devices.
I hear my external harddrive working... so it must be doing something... so I guess its not all USB devices that are down.
I did install new logitech software last week, but it worked fine for several days, just quit working when it woke from sleep. I'd love to uninstall it, or do a system restore, but I can't do that since the mouse is not working.
Any suggestions/help would be greatly appreciated.
