Take the memory chips down, put a new eraser on the chip and wipe it down. There is a battery on the motherboard. Take it down and go in
Unplug the power directly, generally does not damage the computer, but some faults can be solved by yourself. Please try it1, unplug the power, open the case, pull out the memory, wipe the contact point with soft cloth and plug it back into the computer. Be careful not to screw in!!! Boot try;2, the graphics card to remove the fixed screws, pull out, with soft cloth gently wipe contact points, plug back to the computer, boot up try; troubleshooting is that the poor contact fault!!Because the contact point of the plug is more, it is easy to cause bad contact.. If not, there is a real hardware damage, to find professional maintenance. Good luck!!!
