The computer has a black screen of death after being turned on for a long time, and what should I do

If it is automatically turned off just after it is turned on, or it has nothing to do with the long or short boot time; There are many general failures in the operating system; Just follow 4; If there is a regular situation, such as 30 or 40 minutes after the shutdown; Generally, there are many components of hardware failure; Just follow 3; Computer failures such as computer failure to boot, freeze, black screen, blue screen, restart, and stuck operation can be solved according to the following items: 1. First.

Check the power supply; 220V AC power supply (plug and socket are usually called); Then check the output voltage of the computer power supply (desktop check the fan of the power supply, notebook can listen carefully to see if the CPU and graphics card fans in the machine are rotating); 2. Look.

whether the computer can "self-test"; If you can self-test, you can generally reinstall the operating system; 3. If it is a black screen, focus on the inspection parts (including all the causes of the black screen): CPU; Mainboard; Memory; Graphics; display (desktop display); Power supply (Yes.)

output, but the supply voltage is incomplete); and the plug-in parts and connecting wires of the above-mentioned parts;

4. Check and clear.

For viruses, reset the BIOS and reinstall the operating system. Reminder, if the fault persists after reinstalling the operating system and it is confirmed that there is no virus, you should consider replacing the operating system disk and trying again. In addition, after the system is installed, it is best to complete the patch before using it; to reduce the threat of viruses.

You're doing the right thing about the continuous oven, putting the product you've earned for money to the test. If there is such a problem in less than half a month, you can go to the boss, he will help you detect troubleshooting, and he will replace the problematic things, and your legitimate rights and interests will be solved.

If it continues like this, I preliminarily determine that it is a problem with the motherboard I hope you will contact ** business as soon as possible to solve it as soon as possible.

It is estimated that the heat dissipation is not good, and the problem of crash usually occurs if the heat dissipation is not good. My computer is like this, sometimes it freezes after playing for a while, the screen doesn't move, and the keyboard doesn't respond. There was also a loud "pop" sound.

During heavy workloads you check the temperature of your CPU and graphics card. Isn't that so.

And you have to rest your computer and don't torture it. Running continuously for such a long time is a huge drain on its hardware life.

Inferior parts] A small number of unscrupulous businessmen use low-quality boards, memory, and even counterfeit motherboards and remarked CPUs and memory when assembling compatible machines for customers, such machines are very unstable when running, and crashes are inevitable. Therefore, users should be vigilant when buying a machine, and can use some newer tools and software to test the computer, take the test for a long time (such as 72 hours), and strive for the longest possible warranty time.

Crash caused by software reasons.

The crash may be heat dissipation, but your CPU temperature is not high, if it is an automatic shutdown, you have to redo the system, the system is poisoned, and the system files are corrupted.

It's not a CPU heat dissipation problem or a power supply problem, the new computer can be repaired, and if the service is good, it can be repaired for free.

There may be a problem with compatibility,,It's best to ask the next computer.。

Check the CPU, it's really not good to find a computer master!

Maybe it's because of the high temperature.

Disassemble the case and touch the CPU heatsink to see if it's hot. Do CPU fans still spin? In this case, the CPU temperature is too high in the first place. Out of self-protection, when a certain problem is reached, it will shut down and crash.

Black screen,Crash,Hardware problems,Decisive change of host,There's no other way.,Blue screen can be solved.,Black screen.。。。 Love can help!

The black screen and crash may be due to insufficient memory or system problems, and there will also be problems with the hardware configuration, which one is yours?

First of all, see if the heat dissipation is not good, if the heat dissipation is not a problem, try to reinstall the system.

My computer also often has a black screen, definitely not a heat dissipation problem, definitely not a system problem, I have a system disk, I have reinstalled winxp, win7, win8, win10, and the result that these systems will still run black.

Don't reinstall the system at every turn, the reinstallation system will use advanced formatting, which will cause great damage to the hard disk. I usually advise my clients to reset the system as much as possible to minimize the damage, and I will not propose to reinstall the system until absolutely necessary.

Have you thought of the black screen of death on your computer or is it a hardware compatibility issue?

The reasons and how to deal with the blue screen that cause your computer to always be blue are as follows:

The first type: If your computer often has a blue screen, whether you have not reinstalled the system, or later reinstalled the system, or there is a blue screen, it means that it is a problem with your hardware, and the direct hardware is a memory module or graphics card. Generally, this is due to the blue screen phenomenon caused by the oxidation of the gold finger of the memory or graphics card or poor contact with the slot.

The solution is: you can turn off the power first, open the compartment, dial out the memory, use the eraser against the part of the gold finger (that is, where there is a copper sheet,) and wipe it back and forth a few times, and then change a memory slot to plug it back, it's OK, if you do this or a blue screen, you have to check the graphics card, indicating that it is a problem with the graphics card, and it is OK to do it with the same method as above. Generally, 80% of computers can solve the problem.

The second type: is the hard disk has a bad sector, when the computer reads the bad sector, it is stuck, the background is still running, the CPU occupancy is immediately very high, and then the blue screen, processing method: under normal circumstances, it is repaired with HDD, if it can't be repaired, which can only change the hard disk.

The third situation: that is, the video memory and the graphics card's video memory chips appear virtual soldering, and the blue screen will continue to appear, the method is to add solder to the video memory

The fourth is: the computer is poisoned, causing the memory to enter the virus, destroying the operating system, causing the system to be unable to boot, and the blue screen is all the time, where to reinstall the system, or one-click restore.

Fifth: It is because of illegal shutdown, such as power failure, forced shutdown, or sudden crash, after turning on, it will be self-checked, it is also a blue screen, in the countdown, under normal circumstances, let it read it by itself, it is OK, it may waste a little time, but it must read it by itself, because this is the process of checking the disk by the hard disk, generally read it for the first time, and it will not appear next time. Don't stop with ESC, you can't have a blue screen next time, start again.

If you want to self-test every day, you have to start running ---chkntfs after entering the system

t:0", the general problem is solved.

Before doing the above, it is best to restore the BIOS of the motherboard to the factory value, or you can discharge the motherboard battery, that is, remove the battery, wait for 20 seconds and then install it back, or connect the jumper to two or three, which is conducive to eliminating strange phenomena caused by the disorder of the motherboard BIOS.

I don't know if I'm asking.

A black screen is a common phenomenon, especially on older computers or builds. There are many reasons for the failure of a computer black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a poor contact of the graphics card, a damaged power supply, a damaged CPU, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first.

For ordinary computer users, professional knowledge is insufficient, you can follow the following steps to analyze the cause of the failure, so that you can do it yourself.

Start by checking that the contact is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

If there is no problem with contact, it is best to try a different monitor to make sure that the monitor is fine.

If there is no problem with the monitor, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if not, you can change the power supply to give it a try.

If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound. If the memory fault is ruled out, only the CPU and the motherboard are left.

Change to a normal CPU (should be compatible with the tested computer), boot the computer and re-test, if the black screen still appears, you can only change to a motherboard, and the problem should also appear on the motherboard.

A black screen may indicate a serious problem with your computer, and you may wish to eliminate it as described above when the black screen occurs. In the process of treatment, the method of exclusion and substitution should be flexibly applied, and the phenomenon that occurs in a timely manner should be excluded.

1) The monitor is powered off, or the monitor data cable is in poor contact. In addition, the computer has been used for a long time, and the power cord of the monitor is easy to oxidize and break;

2) There is no power supply to the motherboard;

3) Poor contact or damage to the graphics card;

4) Poor CPU contact;

5) Poor contact of memory modules;

6) The machine is infected with CIH virus, and the BIOS is refreshed destructively;

7) Check the plugging and unplugging, if necessary, you can use a rubber to remove the oxide film on the gold finger;

8) If the floppy drive has a floppy disk, many times it will cause the computer to start or restart, and the computer will have a black screen and cannot enter the system. To avoid such situations, it is also possible to cancel the floppy disk boot item in the BIOS.

The main thing is that there is an error, it may be that the graphics card drive is not suitable, and sometimes it is done by abnormal shutdown.

1. Use the computer manager hardware to test the temperature of the CPU, graphics card, and hard disk when playing games to see if the temperature is too high and automatically shut down, if the temperature is too high, you need to clean up the dust of the host, and place the host in a ventilated place.

2. Check whether the memory module is plugged in tightly and whether there is too much dust in the memory module slot. Pull out the memory module and wipe the gold finger with an eraser, and clean the memory module slot.

3. Whether the power supply quota is too small, resulting in insufficient voltage, whether it is too close to the quota of the power supply or exceeding. If it is a problem with the power supply, the power supply needs to be replaced.

There are many reasons why the computer often crashes, see if the fan is running, or if the power supply is overheating, if it really doesn't work, take it and fix it.

How to deal with laptop crash black screen restart.

This is the reason for the aging of the host. There are a lot of specifics, CPUs....Graphics; , you have to come to the repairman to see it to be sure, but generally the motherboard is too old. It would be nice to change one. Hand hope adoption!

In terms of hardware, the CUP temperature may be considered to be too high, and the memory and board are incompatible. The software part can consider system viruses and system corruption.

Check if the CPU fan is spinning slowly. Focus on checking the graphics card, whether the temperature of the graphics card is too high, and you can change the graphics card if you have the conditions to try it.

Heat dissipation problems Pay attention to the cleanliness of the computer There is also the heat dissipation paste may be dry CPU fan power supply and so on Check it Sometimes it is because the power supply is insufficient to cause this situation.

The loud sound of the case is generally a fan problem inside, and you can go to them soon after you bought it.

The following reasons may be present

1. Software Failure.

1. Virus, use 360 security guard to kill malware and Trojan. 360 anti-virus all-round investigation and killing!

2. There are too many running programs and software conflicts. Turn off unnecessary software.

3. If there is a problem with the system, reinstall the system.

2. Hardware failure.

1. Memory failure, too much dust, and poor contact of memory slots will cause crashes.

2. Poor CPU heat dissipation, resulting in protection and computer crash.

3. Hard disk problem, hard disk has bad sectors.

4. Motherboard problems.

5. The power supply is unstable, which will also cause a crash.

CPU heat dissipation problem, open the case, brush the ash under the CPU fan, that is, on the heatsink, and remove the fan if possible.

There are several possibilities for this situation, first, check the condition of your graphics card fan, which is generally a problem of insufficient heat dissipation. (This is more likely).

Second, check your motherboard, whether there is a bulge of capacitors on the motherboard.

Third, check your hard drive and system.

Fourth, check your memory module, or replace the slot.

Machines 5 years ago were generally HY 128m and 256m memory. This memory is unstable. Prone to some minor problems. And it's been used for so long.

Solution: Try changing the memory. or if the CPU fan is normal.

Besides, if you install the XP system, the machine will be very slow.
