When everything is working on the computer, unplug the memory module to wipe it, then plug it back i

In the boot state, first unplug the ** line of the monitor from the host,See if the monitor shows no signal input,If it is displayed, it means that there is no problem with your monitor,The problem is on the host。 If there is no display, there is a problem with the monitor itself.

If it is a problem with the host, you can remove the CPU fan and turn it on, feel the temperature of the CPU with your hands, if it is hot, it means that the motherboard is working, the problem is on the graphics card, check the auxiliary power supply of the graphics card. If it does not heat up, it may be a problem between the motherboard, CPU, and memory, it is recommended to unplug the memory and CPU, deal with the electric shock, and try to install it again.

Good luck!

There are several workarounds for the black screen:

1。Try to boot the computer, after the computer brand is out, press F8, press Enter, Enter, enter the safe mode, and start advanced.

options, the last correct configuration, Enter, Enter, press to try!

2。Enter safe mode, start normally, press enter, go to the desktop, and use antivirus to kill the whole disk!

3。Use: Defender conducts a comprehensive physical examination of the computer, detects and kills the Trojan horse, and repairs the computer.

4。Unplug the graphics card and memory sticks, erase them, use a brush again, clean the slots of dust and fans, replace the memory slots, and more!

6。If you still can't turn it on, you need to "one-click restore" or "reinstall the system"!

Hope it helps

Dear, hello, I'm glad to answer for you, the computer boot display display no signal may be the memory module damage, may oh In many cases, the reason for the display no signal is that the monitor data cable socket and the computer graphics card port are not plugged in tightly, or the contact is poor, has fallen off, or the data cable of the display is damaged. Usually encountered displays. After we rule out the reasons that are not the above faults, the second major reason for the lack of signal on the monitor is that the memory module in the computer is loose and the graphics card is loose, in this case, we can turn off the power of the computer and disassemble the computer host.

After the above methods are handled, if the fault is still not eliminated, then it is very likely that the memory or graphics card is damaged, if possible, we can eliminate the fault and solve the fault by replacing the memory or graphics card, false.

a.First, check whether the monitor is powered on normally, check whether the indicator light of the monitor is on normally, and make sure that the power cord of the monitor is connected correctly.

You can try to turn the switch on and off, pay attention to whether the monitor is responsive, if you turn the monitor off and turn it on, the screen prompts 'no signal' or 'no signal', indicating that the monitor is powered on normally.

b.Make sure that the signal cable (VGA DVI HDMI DisplayPort) is connected to the monitor side - also make sure that the other end of the cable is firmly connected to the display output (graphics card) of the computer, try to plug the 2 ends of the display output cable back in and out to make sure that all the pins are not bent.

c.Confirm whether the display output of the monitor is set correctly, for example, if the display output of the monitor is HDMI interface, the display output of the monitor needs to be selected as HDMI display output.

d.Replace it with the same cable (VGA, DVI, HDMI, displayport) and reconfirm.

e.Connect the monitor to another computer, confirm whether the monitor outputs normally, and troubleshoot the monitor.

The situation you said should be a typical power-on without display,In this case,In fact, the host should not be started,It can only be said that it is powered on,In this case,It is recommended that you check and repair the motherboard to see。

To focus on checking whether the signal cable connection is reliable, if it is still the same after replugging, you can try to borrow the same signal cable connection, if the problem is still not solved, please try to use the "exchange method".

That is, connect this monitor to a normal computer, and connect the monitor on a normal computer to this computer to determine where the fault is.

If you can't clean up the memory module, you can try to restore the motherboard BIOS, unplug the motherboard battery, let it stand for a few minutes, and then install it, if these two methods don't work, you can only go to overhaul the motherboard. There's also the fact that you have a discrete graphics card, and you plug the monitor into the integrated graphics card.

Is the fan at the CPU rotating? Perform COMS discharge and emptying under power failure, then check the boot switch (directly short the motherboard boot test), and only one test under 2 memory. Is the above solved? If the repetition fails, consider the power supply or motherboard failure...

It doesn't have to be a problem with the memory module, the CPU or the motherboard are all possible.

There are several possibilities for this to occur.

First of all, check the power supply, try to change the power supply, whether it is caused by the power supply failure and not working normally. If yes, replace the power supply.

Second, check whether the motherboard has bulging capacitors, it may be that the capacitors are bulging, resulting in unstable power supply to the motherboard, sometimes it is turned on, sometimes it can't be turned on.

Third, the problem of the graphics card, try to replace the graphics card, it may be a problem of the graphics card, the graphics card is not enough power supply or the graphics card memory is damaged, similar problems will occur.

If it has nothing to do with memory, don't keep plugging and unplugging memory repeatedly, so as not to shorten the life of the memory.

If the landlord uses dual memory, he should pay attention to the model to be consistent, and it is best to take the same brand, there are DDR2 667 or DDR800 parameters on the memory, pay attention to take the same, and the memory of the frequency will not make the computer read correctly, resulting in crashes and other phenomena.

The place where the memory module is too loose.

Wipe the slot off with an air gun or a clean cloth and wipe off the memory gold finger with an eraser.

If it doesn't work, please change to a good memory, can you? Not yet... It's that there's something wrong with the memory slot of your motherboard, and it's not in good contact with the memory,。。

There are dead pixels in the memory, this can't be helped, change the memory.

It may be caused by poor contact between the memory or graphics card and the cables, or poor heat dissipation.

Processing: Generally, it can be recovered by restarting, if it is invalid, the operation is as follows:

1.Shut down (if short press the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turn on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you can't do it, then it's simpler:

Palm or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back; Attention said: Don't push too hard, of course, don't be weak).

The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

There are only two memory slots on your motherboard, it is recommended that you test the two memory slots with a memory card respectively, sometimes, there is a problem with the motherboard memory slot, it may also lead to this power-on and no display failure, in this case, you need to repair or replace the motherboard to solve.
