It is difficult to imagine that today a modern person can do without a computer . He needs us at work, with his help we can find the latest news, relax, after watching a good film, or just chat with friends. And so, one day we find that when the system starts, the monitor does not turn on. This causes panic on the layman, but pulling himself together, you can try to find out the cause of the problem, and, perhaps, eliminate it yourself.
Why does not the monitor screen turn on when I start the computer?
There are several reasons why the computer turns on and the monitor does not work. All of them are solved, but nevertheless have a different degree of complexity of their elimination. If the user does not understand the computer hardware at all, then it is best to invite a specialist from the service center to diagnose it. The call will cost money, but they will be justified, especially if you really need to quickly restore the efficiency of your electronic assistant.
The first reason is that there is no power to the monitor or it is connected incorrectly
When starting, the monitor does not turn on when there is no electricity connected to it. Often this is observed when the PC is first installed in the workplace. Just someone inadvertently loosely plugged the cable plug into the monitor, or into the system unit and because there is no contact there is no picture.
To check, it is enough to take out and insert the cable back into the monitor and the system unit in turn. If nothing happened and the picture does not appear, then try using a different connector. It happens that instead of connecting to a discrete video card, it can be connected to an integrated video card, and then it will not work.
The second reason is the video card problem
You can expect that sooner or later the video card may fail, and then the extinct screen will indicate its failure. But, most often just clean the oxidized contacts and the video card will function again. To do this, remove the cover from the system unit, remove the dust and carefully clean the contacts.
Also, if the PC was recently on repair, then maybe the video card was inserted incorrectly or the contacts are not sufficiently tightened. It needs to be rechecked - suddenly the problem is here.
In addition to the failure of the video card, there may be problems with its drivers. If new ones were installed or old ones were updated, their settings could be lost. In order to make sure of this, you need to remove the old driver by logging in through a secure login. To do this, immediately after pressing the Start button, you need to press and hold down the F8 or F4 key for a couple of seconds.
The third reason is the operating system is faulty
If the monitor does not turn on on the PC at startup, the OS may be to blame. Perhaps it had just been reinstalled, and it was done by an incompetent person. Or the computer has suffered from a virus, and maybe the user himself is guilty if he incorrectly installed any program related to visualization.
Either way, you need to log in through a secure login, check the system for viruses and reset the settings to previously installed. If nothing happens, you will have to reinstall the system.
The fourth reason - the monitor broke
Only 10% of cases, according to experts, can be attributed to a breakdown of the monitor. He could warn in advance about the imminent failure of the stripes on the screen and other changes, or stop working suddenly if burned by a voltage drop. In any case, most likely you will need to replace it, if the service center is powerless.
Why does not the monitor turn on when I start the laptop?
Just like a PC, a laptop can sometimes refuse to turn on the monitor. If there are no serious problems, then you can fix the situation by removing the battery from its socket and clamping the power button for half a minute. Most often it helps. But if the monitor does not light up, you will need to reset BIOS settings. To do this, press the F9 key and return to the factory settings. Anyone who does not understand how to do this should contact a specialist.
