Acer Aspire E15 E5-576g wont boot

Hi!
I was having a problem that when I picked up the laptop from the corner it just would freeze and I had to restart it with the button. In other thread someone told me to check the connectors inside the laptop. So I openned it and disconnected everything. I also wanted to repaste the gpu and cpu. But the last screw of the cpu cooler didnt come off. So I decided to use a screwdriver to breake it (like if the screw driver was a drill). I stopped doing that because I wanted to check if it would boot up ok, and it did. So I continued "breaking" the head of the screw so I could remove the heatsink. The screwdriver slipped off the screw like 4 times hitting, not really hard, the motherboard; it seemed ok. But when I plugged everything back in, it wouldnt boot. The light for charging would turn on and also the blue light indicating that it was on. Also the fan would spin. And the keyboard lighted up. But nothing appeared on the screen. I connected the laptop to a screen but nothing appeared. I dont know what could have happened.
The screw was the one circled in red in this video. I'm disappointed with myself now. I would appreciate any advice or suggestions.
