The computer will always freeze unconsciously, occasionally the screen will always go black, and the

First check whether the line is smooth, whether the hardware is in good condition, if the line is good, focus on checking the CPU heat dissipation, to ensure that everything is okay and similar situations will occur in the future, it should be poisoned, **antivirus software to check and kill.

Software:

1. The user is controlled by a remote Trojan, and everything on the computer is in the hands of hackers.

2.Viruses or malicious plug-ins invade the system, resulting in system damage.

3.The driver installed on the computer is not compatible, and the computer will crash after running for a period of time.

4.The compatibility of the software itself, the serious conflict between the software incompatibility and the system conflict, and the computer crashes.

You redid the system and have similar problems, then it depends on the hardware side.

Hardware:1The device is unstable due to poor board contact or quality problems (try to reinsert the memory and graphics card after power failure).

2.Poor heat dissipation of the computer causes the CPU or graphics card chip to crash due to high temperature, including hardware design flaws, such as some recalled graphics cards or computer parts (see if the CPU fan turns If you have an integrated graphics card, it is recommended to unplug the discrete graphics card and try it).

If the system is restored, you have to check the computer hardware, of course, you first have to clean up the dust inside the machine, and then you check the hardware, the common hardware failures of the computer crash are hard disks with bad sectors, poor memory, and system problems, of course, now the system problems are eliminated, then you use the replacement method to check it.

Mine too, killed 5 stubborn viruses a few days ago. After killing and restarting, the driver is gone, and the new hardware is prompted when it is turned on....I installed it, installed the driver, and the next day it appeared again, and I got it right, and today it broke again....I'm too lazy to get it, so I went to install a new system, and now it crashes in the middle of booting! I'm going to go to the warranty tomorrow, who knows what's going on?

The computer was struck by lightning 2 months ago.

Suggestion, full grid, reinstall the system. If that doesn't work, try changing the memory. No, it's usually a problem with the hard drive. If it's not good, send it to the pit.

1. If the screen is black when running a specific program, please try to uninstall the program and reinstall it, or install it in a different version.

2. Enter the safe mode, and confirm whether there is a black screen in the safe mode? If the security mode is normal, it is usually caused by software conflicts, please check whether there are any recent system optimizations and software installation operations, and you can uninstall the recently installed updates and program software through [Control Panel] - [Programs and Functions].

4. Check whether the computer has been installed with memory or other hardware? If so, please remove the additional memory and other hardware before turning on the computer to confirm.

5. If it still doesn't work, it is recommended to back up the data and try to restore or reinstall the system.

6. If you still can't solve the problem through the above methods, please bring the machine to the service center for testing.

Is the screen black and the screen flashes and flashes mine before because of the pirated version of the system expiration.

It may be that there is a problem with the driver.

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 after entering the system: start - run ---chkntfs t:0", and the general problem will be 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. 1

1. Poor heat dissipation: The display, power supply and CPU generate a lot of heat during work, so they have good ventilation.

If the monitor is overheated, it will cause color and image distortion and shorten the life of the monitor. Working too long can also cause the power supply or monitor to dissipate heat poorly, resulting in a crash. CPU heat dissipation is an important issue related to the stability of computer operation, and it is also the hardest hit area for heat dissipation failures.

2. Dust killer: Too much dust in the machine will also cause crash failure. If the floppy drive head or optical drive laser head is contaminated with too much dust, it will lead to reading and writing errors, and in serious cases, it will cause the computer to crash.

3. Memory module failure: It is mainly caused by loose memory module and its own quality. Memory module contact faults should be eliminated on a case-by-case basis, and if there is a problem with the quality of the memory module, the memory needs to be replaced to resolve the issue.

Solutions to common faults with black screen when computer boots.

If there is a problem with the hardware, you can use the soft and then hard method to troubleshoot the fault.

First of all, reinstall the system with the pure version of the system disk, all hardware drivers, all use the official website version, this configuration, has the best compatibility and stability.

If the reinstalled system still freezes, it may be a hardware issue.

First of all, clean the gold finger of all boards, especially the gold finger of the graphics card and memory, to see if you can solve the problem. If not, the possibility of hardware failure cannot be ruled out, and it is recommended to send it to a repair shop for testing and maintenance.

If the screen is black for no reason, you can check the hardware, and the software can redo the system, and you can basically judge that the power supply and motherboard are likely to have problems!

The problem description is too simple to make a specific judgment, but in general, the black screen of the notebook is basically due to the following reasons:

1. Unable to start (only the power indicator light is on, and the other lights are not on):

1. The power supply battery is out of power or the interface is not in good contact.

2. Poor contact caused by memory damage or oxidation of the memory interface (there is usually an alarm) 3. CPU damage.

4. The motherboard is damaged.

2. It can be started (the power indicator is on, and the hard disk light is flashing):

1. BIOS refresh failed.

2. The motherboard battery fails.

3. The display chip is damaged.

It may be that there is a problem with the graphics card or monitor, check the graphics card first, and then rule it out before determining whether there is a problem with the display!

There's something wrong with the monitor. I've been in this situation before, and it's OK to change the monitor.

There may be some problems with the system, and you can go to the seller to reinstall it.
