Computer black screen failure in life is very common, the reason for the black screen of the computer is because of the hardware signal reception interruption, many people encounter the computer black screen after the first time to go to the computer repair shop repair, many repair shops are diagnosed as computer hardware failure, maintenance costs generally from tens to hundreds of yuan range, to be honest, in some cases these money spent really wrong, today I tell you, the computer in the following three cases appear black screen phenomenon, please do not rush to the repair shop, safety can be repaired by yourself, Notebooks and desktop computers are common.
The main computer is running, and the monitor is black
1. The computer that has not been used for a long time, but when you want to use it, there is a black screen when you want to use it.
Whether it is a desktop computer or a laptop, as long as it is not used for a long time, it is likely to appear when you want to use the phenomenon of black screen at boot, the fault phenomenon looks like a hardware failure, but it is not a hardware problem, but a hardware compatibility problem, the solution is also very simple, reinstall the CPU or memory module hardware can be 100% solved. But if you go to the computer repair shop for repairs, it may be "wool", most of them will be judged as "motherboard failure", just imagine, this maintenance fee is not more unjust.
Simply disassemble and install the memory module and CPU hardware
2. A black screen appears during or after the software is installed on the computer.
Installed software to destroy the system structure can lead to a black screen phenomenon on the computer, update system vulnerabilities and patches can also lead to a black screen phenomenon on the computer, install or update graphics card drivers can also lead to a black screen phenomenon on the computer, not the computer in the use of the process of suddenly "burned", no need to go to the repair shop repair, just restart the computer into [Safe Mode] within the operation can be, remove the newly installed software programs or uninstall updated vulnerability patches and graphics card drivers.
After the computer is turned on, the screen is black, and the cursor in the upper left corner flashes
3. When the computer is turned on, the screen is black, and only the cursor in the upper left corner of the screen flashes.
When the computer boots up, it directly black screen, only to see a white cursor in the upper left corner of the screen flashing, this is because the computer operating system did not start the reason, to be precise, the computer's startup mode or settings have a problem, just enter the BIOS settings, set the hard disk to the first boot item, or the hard disk boot mode has a problem, no need to go to the repair shop to reinstall the operating system, not to mention the hardware cause the computer black screen.
These three kinds of computer black screen phenomenon can be completely self-repair, no need to go to the repair shop for maintenance, not the hardware problem caused by the computer black screen, please know.
