Why does HP ProBook 455 G8 restart when pressure is applied at bottom?

I noticed that when pressure is applied to the bottom of the laptop it will restart the laptop without any errors. Earlier when it was discovered it will show a BSOD or mostly a HP Wolf Security saying that i program tried to access a memory bla bla. But now it just restarts it and that's it.

What i already did was open up the laptop to check if there is anything that is touching the base causing it to restart but nothing. I also put a little peace of paper on a metal part inside the base to see if that is causing it to restart, but that also didn't help.
