Or if there is a problem with the wiring of the monitor, check whether the two ends of the power cord and the electrical socket are in good contact.
2. If the graphics card is in trouble, replug and unplug, clean the gold finger, and whether the fan is normal.
If it doesn't work, you will be asked to replace it free of charge during the warranty period.
3. If there is a problem with the cable, plug it back in and check the VGA or DVI interface.
4. If you check that there is no virus in the system, it may be a heat dissipation problem. After using it for a long time, you can open the case to carefully sweep the dust inside, and add a little high-grade oil to the fan. The main problem is to reduce the temperature inside the chassis.

Anonymous users2024-02-04It's better to borrow a display and replace it first to see if there is a problem with the display. If the display is fine, most of them are system problems. The above problems occur after a long time with the old display.

Anonymous users2024-02-01This is because of the power protection of the system, which will cut off the display signal when the system has not been operated for a long time. It can be solved by setting the time when the screen is automatically turned off yourself.
1. Click the Start button and click Control Panel.
2. Click "Power Options" in the control panel.
3. In the Power Options window, click "Select the time to turn off the monitor" on the left.
4. In the planning window, there are 2 settings to turn off the monitor, one is effective for just using the battery, and the other is effective for plugging in the power supply, and you can set the display off time according to your own preferences.
5. If you want to restore the default settings, click "Restore the default settings of this plan".

Anonymous users2024-01-301. Problems with the computer host. Because the black screen occurs in the standby state, the computer will turn off the display indicator after a certain period of standby to enter the energy-saving state, but some hosts can standby normally, and when the machine is used again, the computer is not responding, and the computer can not be transformed back to normal working state, of course, the monitor does not receive the signal that the host is turned on and will not light up, if the standby screen is black and press any key on the keyboard, if the hard disk flashes, the host can switch between normal and standby state.
2. Graphics card problems. Some graphics card problems are frequent black screens, no obvious rules, it is a hardware problem, if the graphics card does not output the normal field signal required by the display, the display will change from a green light to a red light standby state, if you are sure that the computer system is fine, the graphics card driver is fine, that is the graphics card itself has a problem.
3. The model is actually a problem of the graphics card or the display, and the easiest way to do it is to find a graphics card or monitor to replace it.

Anonymous users2024-01-29The computer won't turn on, and the screen will turn off automatically.
Hello, the computer can't turn on, and the screen has been automatically turned off The suggested solutions are as follows: 1. Please try to press the combination function keys to increase the screen brightness, turn on and off the switch display, and avoid the screen brightness being too low or the computer black screen is not displayed due to the silver sedan turning off the screen. 2. When the "black screen" suddenly appears after booting, please pay attention to whether there is an alarm sound from the PC speaker in the computer.
If the PC speaker emits an alarm sound, then you can preliminarily determine the hardware part that may have problems according to the length of the sound. 3. If there is a problem in any of these steps, the computer will not start normally, or even a black screen. Countermeasures:
First, make sure that the external wiring and the inner vertical drain are connected smoothly.
It's also possible that the network management restricts the use of the external network, and how to connect to the external network will automatically shut down, which is the case with mine, and finally I must solve the problem with the registry.
First of all, check whether it is caused by overheating, if not, then whether your QQ speed car and game are overloaded, and finally check whether your power supply is stable. >>>More
The specific situation is analyzed, you can also set it, sometimes it is a system problem, sometimes it is to protect the computer system automatically restarts, and sometimes it is accidentally touching the switch, and the voltage is unstable. Poisoning. And so much more.
This has nothing to do with disabling, starting, etc. It can be achieved without any other operation,Of course, it is very likely to use 360 to scan the boot network card to k,It can be completely achieved with the following method,But there may be some delay,One more thing to say here,If the machine is not particularly slow,There is no need to use the boot startup item to sort out。 >>>More
1.Maybe it's a Trojan, it's remote control, just reinstall the system. >>>More
