Stuck on Windows 8.1 lockscreen

Help! I was installing Windows 8.1 updates on my Acer Aspire laptop, when it rebooted to the lock screen and now where the words and letters should be, there are all sorts of symbols e.g. triangles, white boxes, ticks and question marks. I now can't access anything. The only key working now is the F2 to access the bios. Could somebody please help? Many thanks.

Maybe unrelated, but my wife's Asus Win8.1 laptop just had a blank screen yesterday after an automatic update. I eventually got it working by taking out the battery and removing the power cord (I don't think it was shutting down properly to complete the update process). I switched it back on using power cord and no battery. It then completed its updating and now works normally.
