Acer Aspire stuck in legacy mode. Doesn’t post anymore. Please help.

Hi. My Acer Aspire started to crash a lot after the windows 8.1 update. So, I decided it was a great idea to see if legacy mode would change anything. Instead I was greeted with a black screen so 8 turned it off. After I turned it back on it wouldn’t post anymore so I couldn’t go to the bios. I’ve tried all the other things in this forum. Please help me.

What "all other things" did you try already so we are not just repeating what you did?
