After the computer is turned on, there will be several alarms, and then the display screen will go b

Problems with memory and graphics cards!!

Just take it down and clean it up.

The CPU temperature is too high, automatically protect, see if the CPU fan is normal.

One long and two short One long and three short are both problems with the graphics card.

You see if it's loose.

The memory is not plugged in!

Or the CPU is loose, or the hard disk cable is loose.

Either the memory CPU fan has a fault, causing the CPU to have a high temperature, and this can also happen.

It seems that the memory is not plugged in properly. You try plugging in the other slots and seeing. It should be that the memory is not well inserted. Try a few more times. An alarm sound indicates that the CPU motherboard is normal. Either the memory or the graphics card is not plugged in.

Remove the lithium battery from the motherboard and put it back on after a minute. Turn it on again and see what it looks like.

Plug the memory back in, or the graphics card back in and out.

If you're a tinkpad computer, flip it over and shoot two ha, the probability of success is 100% in my case, two minutes ago, my computer was normal, !! I just don't know if your computer is skinny, anyway, my skin, hahahaha!

It may be that the laptop's battery is dead, so plug it in and try it.

Summary. Check step by step according to the following methods: 1. Check whether the power supply of the display is loose; 2. Check whether the data cable from the display to the host is not in good contact; 3. Press the power supply for 5 seconds to force the shutdown and then turn it on, if the hard disk light keeps flashing and the keyboard light is on, it means that you can enter the system is only the contact problem between the graphics card and the motherboard, and pressing the graphics card can basically solve the problem; 4. None of the above three situations indicates that the host is faulty, it may be that the memory module is loose or the motherboard is faulty.

The capacitor in the display is blown up or the filter capacitor of the display power board is broken, the former is about 20-30 yuan, and the latter depends on the level of the repairman, but the boot fee is added. Maybe 100 yuan can do it.

After the computer state stares at the orange boot, the screen will be black after a while, but the host sound operation or something is operating normally, and the display will be black after a while after turning off the monitor and turning it on, what is going on, how to solve it?

Hello, dear. We're happy to answer your <>

After the computer is turned on, the screen will be black after a while, but the host sound operation or something is operating normally, turn off the monitor and then disturb the early oak after opening the display screen after a while, and the screen will be black again, this is your motherboard problem, oh pro, you need to change a motherboard.

1. Check the computer's sleep and screensaver settings and power settings to see if the time is set to a very short time or the dusty power-saving mode, and modify the settings. 2. If the problem persists, it may be that there is a problem with the power board or signal board in the display and needs to be repaired.

Check step by step according to the following Fang Hong return method: 1. Check whether the power supply of the display is loose; 2. Check whether the data cable from the display to the host is not in good contact; 3. Press the power supply for 5 seconds to force the shutdown and then turn it on, if the hard disk light keeps flashing and the keyboard light is on, it means that you can enter the system only because of the contact between the graphics card and the motherboard, and pressing the graphics card can basically solve the problem; 4. The above 3 situations do not mean that the host is faulty, it may be that the memory module is loose or the motherboard is faulty. The capacitor in the display is blown up or the filter capacitor of the display power board is broken, the former is about 20-30 yuan, and the latter depends on the level of the repairman, but the boot fee is added.

Maybe 100 yuan can do it.

The reasons for the black screen are generally as follows:1

System files are corrupted or not found.

There is a problem with the driver or driver file (the motherboard or graphics card is more likely)3

Memory module failure (caused by thermal stability or compatibility issues.) Your memory is several: if it's a single one, then you can try to change the memory; If it is 2 or more, and it is a different brand, please use one of them to run separately (greater than 128m) to see if there will be a problem, and then change to other memory, if the problem appears, it can be judged that it is a problem with one of them, if there is a problem with either one, it is recommended to re-install the method:

Check for screen savers, energy savers, viruses, overclocking, collisions, and hardware heating instability.

Steps: (1) Cancel the screen saver. Desktop blank Right mouse button Properties Screen saver Select "None" (2) The protection energy saving setting can also make the screen black, and the way to prohibit energy saving is:

When the computer is turned on, press the del key to enter the motherboard setup, and select "power".

management

setup”、“

powermanagement" and set it to disabled.

3) Use a new antivirus software to detect antivirus. (4) If the CPU is overclocked, a typical fault is a black screen. Boot del into the BIOS settings and select "Load".

default

setup" and then F10 saves to exit.

5) When the chip on the memory, graphics card, and motherboard is unstable when heated, the screen may also be black, which can only be tested using the substitution method.

Note: The black screen is the same as the crash, it is an extremely complex fault in the computer, please be patient to detect the installed system. 4.

The computer's monitor is the window of the computer, and if something goes wrong with it, you can't use the computer.

Good luck friends!

To deal with such problems, you should troubleshoot the hardware one by one, don't rush, and don't panic. If you can't turn on the machine, there is no alarm sound, which is generally caused by a power supply or motherboard failure, from the outside to the inside, remove the peripherals, such as hard disks, memory and graphics cards. If you know more about the computer, directly remove the motherboard battery, boot and power without adding the battery, because there is no memory, the system will be long, because there is no graphics card, the system will be short, depending on the length of the alarm sound plus the corresponding hardware, there is an alarm sound means that everything is normal, but if there is still no alarm sound, you can only consider sending the motherboard or power supply for repair.

Some motherboards are not well designed, alarm sounds come and go, and some chassis are not good at workmanship, and the front speakers are of poor quality and vulnerable.

1. It is possible that the memory module is broken.

2. There is static electricity on the motherboard.

3. The motherboard slot is broken.

It is recommended that you try to discharge it first.

Then carefully rub the gold finger.

You take the memory down. Boot directly. If there is still no alarm sound. That's your motherboard. If it is within the warranty period, take the warranty.
