The screen doesn t respond after the computer is turned on, just turn it on a few more times, what s

Loose graphics card、Loose memory may be that the graphics card driver is not installed or incompatible,It is recommended to use the driver wizard or driver life to reinstall the driver,If it's not good, it may also be a matter of the graphics card,1.Probably your graphics card is broken2Maybe your data cable is broken, and generally speaking, the probability of the data cable being broken is relatively high.

It's the line that connects the graphics card to the display, and the flickering screen is mainly caused by the problem of the graphics card. Take a look at an external monitor, if the external monitor is also like this, you can basically determine that it is a problem with the graphics card. If the external monitor is normal, then the problem with the screen itself or the screen cable is the most likely.

If it's caused by the graphics card, you can:

1.Right-click on the blank area of the system desktop--- click "Properties" -- click "Settings" -- click the "Advanced" option, select the "Monitor" tab in the pop-up display advanced properties setting interface, if you see that the refresh rate setting value of the monitor is less than "75", set the frequency to "75" or a little higher.

2.Update the graphics card driver or reinstall the driver.

3.If it is a discrete graphics card, disassemble the computer and take out the graphics card, clean the gold finger with an eraser, clean the slot, and then insert it again.

The contact is not good, and it is estimated that yours is an old computer

This fault phenomenon proves that the motherboard components have failed and need to be checked and repaired before they can be used normally.

You can open the case, check the capacitance resistance on the motherboard, and if you see any abnormalities, you can pass the measurement verification.

Also check the components of the power block, which may also fail.

If you don't understand, you can take a picture of the motherboard and show me, and I can help you find it.

It must be started many times before it can be turned on, and once it is successfully turned on, it can be used normally; This is a "start-up circuit" fault.

Reason: (1) There is this circuit in the host power supply and the motherboard, (2) but there is a problem with the host power supply or the motherboard.

Solution: 1. Motherboard.

1. After normal starting, shut down again, but do not completely cut off the main power supply, and wait for a certain time (4 8 hours);

If it can be restarted immediately, or at one time, it is generally the "starting capacitance" in the motherboard boot circuit that is out of capacitance;

If it can't be restarted at one time, it doesn't mean that it's a problem with the motherboard;

2. After normal starting, shut down again, and completely cut off the main power supply, and wait for 1 2 hours;

Turn on the power switch of the main unit again and wait for about 30 minutes.

If the computer "automatically boots on", it means that the "starting resistance" on the motherboard has changed (generally the resistance value has increased);

If it still does not turn on automatically after waiting for 1 hour, it does not mean that there is a problem with the motherboard;

Second, the host power supply.

1. If after shutting down, whether cutting off or not cutting off the main power supply, can not be "one-time" or "delayed" to turn on the computer according to the method of the first item, must press the power switch many times and repeatedly to make the computer start, then it is generally the PG (power good, power good) circuit fault of the host power supply;

2. If the number of times the switch is not cut off from the main power supply is obviously less than the number of times the main power supply is cut off, then the starting circuit of the host power supply is faulty.

First, the motherboard. 1. After normal starting, shut down again, but do not completely cut off the main power supply, and wait for a certain time (4 8 hours); If it can be restarted immediately, or at one time, it is generally the "starting capacitance" in the motherboard boot circuit that is out of capacitance; If it can't be restarted at one time, it doesn't mean that it's a problem with the motherboard;

2. After normal starting, shut down again, and completely cut off the main power supply, and wait for 1 2 hours; Turn on the power switch of the main unit again and wait for about 30 minutes. If the computer "automatically boots on", it means that the "starting resistance" on the motherboard has changed (generally the resistance value has increased); If it still does not turn on automatically after waiting for 1 hour, it does not mean that there is a problem with the motherboard;

Second, the host power supply.

1. If after shutting down, whether cutting off or not cutting off the main power supply, can not be "one-time" or "delayed" to turn on the computer according to the method of the first item, must press the power switch many times and repeatedly to make the computer start, then it is generally the PG (power good, power good) circuit fault of the host power supply;

2. If the number of times the switch is not cut off from the main power supply is obviously less than the number of times the main power supply is cut off, then the starting circuit of the host power supply is faulty.

3. In order to facilitate judgment, it is recommended that the landlord first borrow a reliable host power supply to try, so that you can judge whether it is a host power supply or a motherboard problem at one time.

Turn on the CPU cooling fan, which means that it has been powered on, and the display is not responding, which means that the self-test has not passed.

I don't know the specific problem, if you can use the motherboard detection card to detect it, you can find it according to the fault.

Most of the problems are with the motherboard or power supply.

Check the cable and motherboard.

Is the power button stuck?

Answer: The reason why the computer has been restarted repeatedly and cannot be turned on may be: incompatible drivers, high CPU or other hardware temperatures, bad sectors of the hard disk, power failures and unstable voltages, which are described in detail as follows

1. Incompatible drivers can also lead to restart. You need to restore or reinstall your system.

2. Caused by high CPU or other hardware temperatures. In this case, you need to power off the computer and wait for the temperature of the console to drop before restarting.

3. The hard disk has bad sectors: it may be because the host has been impacted, you can use the system's own functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Power failure and voltage instability can also cause automatic restart. You need to check if there is a problem with the socket connected to the computer, and if there is no problem with the socket, you can take it to the computer store for inspection.

4. Install the battery, restart the computer and you will find that the computer can be turned on normally.

Ask if it's a problem with the computer.

After the computer presses power, the host computer is running, but the monitor is not responding. After running for a period of time, force the main unit to turn off and turn on again, and sometimes the display will light up normally. (like a warm-up).

But there is still a problem after it is lit.,It's that it keeps restarting automatically.,Not necessarily to start to which step it will suddenly reboot again (sometimes it's a blue screen.,Most of them are restarted directly),It takes several times to enter the system normally.,But after entering the system, the number of automatic restarts is very small.,Two or three times.。 Methods I've already used:1

One-click restore to the original backup of the system without problems, still like this. 2.Reinstalled the system and all the programs, and it still didn't work.

3.I took it outside to repair, and the man said it was a problem with the motherboard, and said that it was a bridge (I don't know what it was), and the display was directly lit up at that time, but it was like this again the next day. I'm almost **, please ask the computer expert to help explain it, and also talk about the solution in detail, I give a high score!

I will add points after the solution!

The computer can't be turned on after repeated restarts, see how the god solves it, you can also learn.

Hello landlord! Depending on your situation, the possible cause is that your motherboard is underpowered, and the reason is most likely that there is a problem with your power supply. In addition, it is best to use the MHDD hard disk detection tool to check the hard disk when the machine is running normally to see if there is a problem with the hard disk, and also check if there is a problem with the memory.

Finally, if you have the conditions, you can test it with a different monitor to see if there is a problem with the monitor. Hope it helps!

If the graphics card driver is up to date, this is your graphics card or memory dusty, unplug it and sassafras a gold finger OK

The display doesn't light up maybe it's a hardware problem.,It doesn't have much to do with the graphics card driver.,Even if you don't install the graphics card driver, there won't be no image.。

Either there's a problem with the graphics card, or the monitor signal line is broken.

I don't understand that I'm going to go around in a circle, reinstall the graphics driver, drive the wizard.
