Finally, I can now enable the arrows to move up and down in Safe Mode, but new problems have occurred, for which I am having to use another person's computer.
A Windows Update seems to be the initial cause of the problems, as I kept getting prompted after Start Up to install my already installed Microsoft keyboard after installing the Windows update. It turns out that this update is not recommended (and won't uninstall, as it's not listed in Windows Updates but was definitely installed).
I attempted two System Restores, but both failed for some reason.
I uninstalled the Keyboard driver via Device Manager, removed the keyboard's USB lead then re-inserted it (from a recommendation to another person online) and I got the prompt to install my keyboard again.
I also tried removing the lead then turning off my computer at the tower. My keyboard now only works to activate Safe Mode, Safe Mode with Networking, etc, and my Mouse light no longer displays. My mouse is already installed, but its light no longer illuminates.
I also noticed my Clock (bottom right of screen) temporarily displayed the US date, eg 04/14/2014 then reverted to 14/04/2014 during Start Up.
A window pops up stating that a device's driver software (my keyboard) is being installed, which takes forever, then, eventually, it says the installation failed.
As I can’t extend the Sleep Mode to delay going into hibernation, it’s pure luck if an Installation update appears in time before my computer goes to sleep.
My keyboard and mouse don’t work on my computer but both play fine on another person’s computer, so it’s definitely something to do with my computer which is obstructing these devices. My keyboard’s Number lock works and the Arrow keys for activating Safe Mode, but nothing more. My mouse doesn’t work at all but it lights up and operates on the other person’s computer.
I have tested the mice on each other’s computers and neither work on mine. I’ve also checked all USB ports, all to no avail.
Since retrying to get my computer back to normal, I had to turn it off at the tower and then got an additional to option to "Repair your computer". I opted for this, but it required a password so couldn’t proceed.
My Online Connection status colour is Yellow, so reduced power, yet the other person's computer is in full online power.
My keyboard only works if I plug in the USB lead before switching on my computer (which activates the Number lock).
For some reason, My mouse doesn’t light up, but while the other person’s mouse on my computer does light up, that, also won’t move the cursor.
CHKDSK came up as an option, with nothing negative found.
The "Safe Mode" etc window option appears without me having to click on "F8".
Also, a folder that I never created appeared during what attempted Start Up called "Home Group Folder".
I then found and tried out the option "Last Known Good Configuration", but this has not resolved the problem. Instead, Avast came up with an "Avast !" error window.
What is causing the above issues? And how do I restore my computer back to normal, without losing files currently saved only on my hard drive?
