Urgent! The computer suddenly won t boot, what s going on

The keyboard light is not lit and there is no signal input It should be that the self-test has not passed The problem may be on the motherboard, but in order to rule out other problems, first check the ** transmission line, that is, the cable connecting the graphics card and the display Whether it is plugged in firmly, and then open the case to check whether the graphics card is loose Then stabilize the motherboard and then restart If it is still so, it can only be sent to a professional repair point for testing.

All the "heroes" upstairs all said that they were poisoned, and they had never seen the poisoned machine without model input?

The guy on the upper floor was right.

If you do what he says, it's useless, and then you do it.

Hehe. Dude、Take out the memory module and clean the connector、

Then blow the computer off the dust

Then the memory module is plugged in tightly

If that's still not going to work、

Check whether the memory module of the next Ling is overheated

If so, it's best to replace the memory module.

It's not a small problem, the system is probably broken, there is no signal, then there may be a problem with the motherboard, go fix it, and solve any problem wherever it comes.

It may be poisoned, or it may have been changed, but it's useless for us to say it here, we haven't seen your true situation, and it's useless to say it, I think you should ask your friends around you, or go to the repair shop to see, but be careful not to let the shopkeeper pit you. Good luck.

It should be poisoned, hurry up and report it to repair

Normally, mine hasn't touched either.

Common reasons for computer boot failure are unexpected shutdown caused by power failure, blue screen, etc., which will occur after restarting the computer.

So how do we solve this situation?

First of all, directly press the normal boot windows, if this step can be done, the following steps can be done without looking at the computer, there is no big problem.

If not, you can enter the safe mode to see if you can enter, you can congratulate the computer on booting up is no problem, the system has recently misoperated caused the boot is not normal, enter the safe mode and then restart it.

None of the above means that a key file of the system is lost or damaged and needs to be repaired, which can be repaired by using the repair function of the system itself (the original image file is required) or by using PE tools.

After so many steps, you can basically solve the problem of 100%, if it doesn't work, you can only reinstall the system, it is recommended to develop the habit of backing up the system, and you can restore it when there is a problem one day.

Is it caused by an abnormal shutdown, do as he says, safe mode. No, you can only do the system, but doing the system will lead to C disk data.

Lost, so try not to do the system, you can also do a detailed check on the host.

If you choose Normal Boot and can't boot, it's basically a system problem, which is recommended for you.

Reinstalling the system is simple and straightforward.

Wouldn't it work if you chose safe mode?

This is a system problem, and it is good to reinstall the system

Press the F8 key once when you turn on the computer, and choose the correct configuration for the last time! Or go into safe mode and go into 360 and change it back!

If you can enter from the safe mode, if you can enter, it is a problem with the driver service, if you can't even enter the safe mode, it means that the system file is corrupted and you need to reinstall the system to solve it.

Boot Windows normally. If that doesn't work, go to the nearest safe mode and restore it. You can't enter the safe mode, so you can only reinstall the system.
