Usually the situation is that the memory module is in poor contact with the memory slot, it is recommended to pull out the memory and then use an eraser to wipe the gold finger, and then wipe the memory slot with a paper towel, and then insert the memory back, so that it is generally OK, if it doesn't work again, take out the battery on the motherboard and discharge it for 1 minute, then reinstall the battery, and try again.

If you have a little bit of DIY ability, just open the case, unplug the memory, rub it off with an eraser, and put it back on, and the problem can be solved.

I bet with you, what I said you did to solve your problem, the computer turned on to give me extra points, I repair the computer drop, remove the memory and graphics card, use a good eraser, such as South Korea, wipe the gold finger of the memory and graphics card clean, it should be a yellow layer on it, that is copper oxide (not energized), install it correctly, the problem is solved! Let's do it! 1！Hehe.

Is there a dripping sound? If not, it means that there is a problem with the motherboard oil.

It should be too dirty, brush the radiator off with a brush, it will be fine.

Wipe the memory module with the gold finger and wipe it clean, and clean the card slot, if it is not good, the motherboard is okay and consider the case power supply.

If there is a problem with the motherboard or interface of the hard disk, there should be a short circuit. It is recommended to replace the hard disk as soon as possible, because if the hard disk is burned by a short circuit, the motherboard and power supply may be burned.

This can happen if the resolution is set too high.

Unplug the memory and wipe it to try.

Remove the graphics card, wipe the gold finger oxide with an eraser, and put it back on. If it doesn't work, dial the power cable and signal cable of the hard disk and reinstall it, and try again to solve the problem.

This indicates that your machine is not booting properly. You first plug and unplug the memory and see if you can fix it.

Check whether there is a power supply on the hard disk interface... It's best to try it with a multimeter Or install the power supply on the drive...

No signal from the monitor? The graphics card fan does not mean that he is okay Look at the power supply I have moved the computer and it is not plugged in or something.

See if the lines are all plugged in.

Replugging the memory module is Yes.

Personal estimate the problem or on the motherboard!

--Suggestion. 1-BIOS reset once, remove the motherboard battery and wait for 10 minutes before putting it back on!!

2-CPU heatsink loosen a little, or simply remove it, and briefly boot it up!

3- Take a look at the power --- is also possible !!

If there is a problem, we have to find the problem and solve the problem. Frequent power outages are very damaging to the computer!

landlord don't worry, listen to everyone's opinions, step by step ! o(∩_o

1. Unplug the memory and try to change the slot, 2. You are several memory, if you keep one in rotation for two to try, it may not be compatible;
