What do I do after my computer breaks?

Recently, my Surface Pro 3 had a big collision inside my bag and the corner cracked, I could see the inside a bit. The crack spread out in one line across the laptop and soon after began forming bubbles along the crack. It soon went away though. When I press the power button, it is stuck on the surface logo and the only way to get in is hard restart. I did that though the lock screen started glitching and had to have someone hold their fingers on the screen while I was typing the password, and then backing everything up. What do I do after an incident like this?

So your saying a big crack spread out across the laptop and soon went away? well that dosent make sense but if your truly expecting guidance after not even giving us info on manufacturer warranty or place of purchase, time since purchased, insurance, i dont know how to help you, you broke it, buy a new one or pay to fix it.
