If I even hit it by mistake with chair or leg very slightly - the screen goes dark
I thought its faulty cable (DP] - replaced it
I thought its faulty GPU - replaced it
Thought it might be the PCIE x16 Connector, so I plugged it to another one, problem persists.
I thought maybe the GPU is so heavy it moves so I bought a bracket that holds it firmly to place - no
what kind of demon is possessing my pc? how do I exorcise it? I cant even more it to do small things like adding ssd or cleaning it...

many thanks
