No touch, mouse, or keyboard input after computer reset

I have an Acer Aspire M computer with a touch screen that runs Windows 8.1. I was having issues with the touch screen, so I went to download the drivers from the Acer website. However, when I restarted my computer to complete the installation, it wouldn't allow me to use either the mouse, touch screen, or keyboard.
Normally, after loading, a personalized picture will appear on the screen, displaying the time, connectibility, and strength of the network. The user is then supposed to swipe up, click on, or press space to move the picture, at which point the login screen appears. My computer loads normally when starting, but won't allow me to use the mouse, touch screen, or keyboard to move the picture out of the way, so I cannot access the login screen.
I have already contacted the Acer company support and attempted to use the battery reset pinhole, but to no avail. Is there anything I can do, besides a factory reset or using it as a cat bed?

Probably best.

You could uninstall those drivers, looks like you will need to do it from outside windows.

You would need a decent winpe., which you probably don't have, nigh on impossible to make one given your situation.

System restore to just before the problem may do the job.

Try that and see.

The only problem is, how am I supposed to do a system restore if I can't even see the mouse?
I realize that I need to boot into windows safe mode to perform a system restore, but I somehow can't get into safe mode, no matter what I press when starting up.
