Playing 3D games, the computer sometimes restarts automatically after the screen goes black

A black screen on a computer is actually a common fault.

From my personal experience, half of the assembly machines and laptops appear more, some are faulty, some are setting problems, and the solution to the failure is generally:

First, check whether the interface and power cord of the chassis power supply are in good condition. If the interface and power cord are damaged or broken, they should be replaced in time

1. The lamp may also fail, and the lamp should be replaced within 500 oceans; ps：xian86913

2. There is also a booster plate, or a high-voltage plate failure, which is an element that supplies pressure to the lamp, generally at the bottom of the screen. The maintenance cost is about 200-300; ps：xian86913

3. If the motherboard does not supply power. That is, there is no power supply to the booster plate. The maintenance is about 200-300 yuan; ps：xian86913

4. Then there is the overheating of the machine, which causes problems with the graphics card; ps：xian86913

5. If the memory is loose, try to see if the memory of the machine is loose, or you can also see if the hard disk cable is loose, etc.

If none of the above can be solved. ps：xian86913

Black screen suggestion: Take it to the manufacturer's repair station for free during the warranty period, or find a computer repair company with a good reputation.

There is also a black screen is a problem with computer settings, that is, it can be solved in this way if you don't use the automatic black screen for a long time:

Tap [Start] in the lower left corner of the screen - select [Control Panel] - find [Power Options] - select [Balance] - click [Change Plan Settings] - set the computer to sleep "Never".

However, if you set it up like this, the hard disk will work all the time, which will have a certain impact on the service life of the hard disk.

Method:1Diagnose the fault first, the black screen can be many kinds.

First move the mouse or press the keyboard to see if the screen can be displayed, and then after confirming that the screen is black, whether the monitor and the host are still powered by the power light, and then the other is to turn on the stereo and listen to whether the sound is still coming out normally.

2.If the screen goes black, the monitor is still lit up. Usually the normal display is a green light, and the no signal is an orange light.

If the display is a green light, then you can first consider restarting the computer, and then update the driver of the graphics card, and then enter the game test. If the orange light is displayed, then we need to check if the host is still working, if the host is working, it is a problem with the monitor. Check the signal cable of the monitor first to see if the contact is not good.

If it doesn't work, replace the monitor for testing, or find a computer company to help overhaul the monitor.

3.After the black screen, the computer console also stops working, and no lights are on (the host computer is powered off). This is to check the main chassis, after unpacking, first check whether the CPU fan is working normally, if the fan does not rotate or rotates very slowly, it is the fault of the CPU fan, causing the CPU temperature to be too high.

If the CPU fan is normal, then the next step is to check the power supply, first unplug the power cord and reconnect it once, see if the contact of the power cord is not good, the problem is still the same, you can consider replacing a power supply to test it.

4.There is also a situation where high-end graphics cards are generally independently powered, and if the power supply is not high, there will also be a black screen when playing games. In this case, the only way to do this is to replace a high-power power supply.

However, this kind of failure will not cause a black screen failure when you use a computer normally. The main thing is that when playing games, the graphics card is working at full load, and the power requirements for the power supply appear as soon as they are high.

What can be done now is to dust the memory and graphics card from the new, plug it in from the new, and contact it well, if you can't solve the fault, you have to test the hardware, you have to rule out the hardware that is not supported, and you have to find a repair station.

Return to the factory for repair! It should be the graphics card or the power supply!

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.

Software:

If you are playing games and dealing with 3D, the screen is blurred, paused, and the phenomenon of crashing, then after eliminating the heat dissipation problem, you can try to change the version of the graphics card driver to try it, and it is recommended to use a driver that has passed the WHQL certification, because the graphics card driver is incompatible with the program itself or the possibility of bugs in the driver is indeed very common. For some graphics cards, you can also try disabling AGP FastWrites and AGP Sideband in the motherboard BIOS.

If none of the above methods work, then you have to reinstall the system, which can solve many problems in daily maintenance. After installing the system, install the drivers in the correct order: Windows XP SP2 patch - motherboard driver - graphics driver - sound card and other PCI device drivers - peripheral drivers.

When the driver installation order is not normal, there may also be some problems, and the driver installation order is related to the underlying device driver, registry key value and gart mapping list.

Hardware: First of all, confirm whether the boot process is normal, if the screen crashes as soon as the display is turned on, then check the heat dissipation of the graphics card first, touch the temperature of the video memory chip with your hand, and check whether the fan of the graphics card is stopped. Then look at the AGP PCIe slot on the motherboard to see if there is dust and whether the gold finger has been oxidized, and then clean up the dust according to the specific situation, wipe the gold finger with an eraser to polish the oxidized part. If there is a problem with heat dissipation, change the fan or add a heatsink to the video memory, or go to the BIOS to see if the voltage is stable.

For the phenomenon of long-term pause or crash or blurred screen, on the premise of excluding overclocking, it is generally caused by insufficient power supply of the power supply or motherboard slot, and it is recommended to replace the power supply to try it. For the power supply problem, many brands in the DIY market (including several big brands that are currently louder) have a nominal power supply of 300W, but the actual output power is only about 230W. Many graphics cards are already products with high frequency, high temperature, and high power consumption, and the requirements for power supply are also increasing.

It is recommended that players with conditions pay attention to the actual output power calculation when purchasing, and it is best not to buy miscellaneous power supplies. Try not to buy a chassis plus power supply for less than 200 yuan cheaply. In addition, if the graphics card slot is not supplied with enough power due to the motherboard's design flaws, you can try to increase the voltage in the motherboard's BIOS.

If the graphics card is still blank after the above methods, you can try to flash the BIOS of the graphics card and go to the home page of the graphics card manufacturer to see if there is an updated BIOS**. For some graphics cards from miscellaneous manufacturers, you can try flashing your graphics card with the BIOS of major manufacturers.

Is the driver of the graphics card expired?

Just update the driver.
