Of course not, Quan.Can you take a photo of the message you see on the screen and attach it here so I can get a better idea of what you see on the computer?
So you press the Power button to turn the computer on and nothing comes on the screen at all?Does the computer make any sound at all?
Does the computer make any sound at all?
Press the Power button for 10 seconds then let go.Press it again to try and turn it on.Do you still hear nothing at all?If you hear nothing your PSU (Power Supply) is most probably dead and needs to be replaced.
Does that make sense, Quan?
