Mouse and keyboard not working after system restore, can't log in

Hi. I have a PC i haven't used for a few years - mostly because my ssd died and when i restored my backup (macrium reflect) to the replacement drive I don't recall it ever working quite as right. I decided to solve this once and for all.

I have a backup that i have restored to my ssd but when i boot up the lights on my keyboard and mouse come on and work (including in the bios) but as windows 8 is loading the mouse goes off. the keyboard stays on but neither of them work when it gets to the log in screen (which is black and white, not colour but should be colour).

i tried safe mode but get the same behaviour.

i tried the advanced boot options stuff but can't restore a restore point (guessing there aren't any saved) or system image (wouldn't have used that feature as i used to use macrium reflect), startup repair says it can't fix anything. i think i can get a command prompt up but don't know what to do.

i was thinking i could upgrade it to windows 10 to see if that helped fix things but realised that i need to do an in place upgrade so i don't lose all my apps, settings, data but can't log in to do that.

is there a way to use the command prompt to setup another user in the hope that will let me log in and then try to analyse what is causing the problems?

i did try unplugging the mouse and kb and plugging them into other usb ports but mouse doesn't work at all and kb has less lights on than when working fully.

i tried booting without kb and m plugged in and then connecting at the log in screen and that didn't help either.

i'm almost certain that one of my RAM modules is faulty as it causes bios to detect 8gb total ram with faulty one inserted where as without it in and the other 3 modules in it detects 12gb RAM (i actually thought the ram was dual sticks or whatever the term is called so that you have to have 2 identical sticks inserted so bios sees them both but not according to this). not sure if this would affect anything?

in bios i have selected legacy usb support enabled.

I'm thinking this is a driver problem - possibly the usb driver?

I appreciate any help out there guys?

thanks for your reply. I have got these enabled, i also disabled the usb device charging feature as i heard that it can cause problems. i don't know why that would even be a feature however because plugging in a device to usb would automatically charge it if it was rechargeable anyway lol.

i think i may have to clean install because everything i've tried just doesn't work
