Hi, hope someone could help me, I have my computer on top of some draws, everytime I close the draw even if I do it gently it knocks my display off the computer, it even happens if I just knock it with my knuckle, the computer stays on the display doesnt, I try to turn the computer off by button but it wont off unless I do it by the psu switch, could someone shed some light on what it maybe as it's driving me insane, many thanks.
