Vostro 5470 is unstable and unusable

I have a Vostro 5470 that is suffering from instability when we move it or touch the right side (next to the biometric thingy). The screen "sparkles"  (I don't have a word to exactly describe that), or a BSOD/kernel panic happens or the computer just froze. Sometimes it doesn't even turn on. And sometimes it works fine.

Someone can guess what this is? I changed RAM and HDD (per friends suggestions) and nothing changed.
