🖥️ The Monitor Won’t Turn On 😱 When PC Starts


Hello everybody! In today’s video, we’ll try to find a
solution for cases when the monitor doesn’t turn on, or when you can do it only after
several attempts. If you faced a problem of black screen while
your computer is on, you will certainly find this video useful. In a minute, we will do our best to analyze
every possible cause behind the black screen you may see when you turn on your computer,
and describe how this problem can be solved. So, you turn on the computer, hear the cooler
fans buzzing, but the screen is missing the traditional lines of text, pictures and BIOS
logo. The screen of your monitor is the same as
it was when the computer was not started. What shall we do now? How to find the root of the problem? Causes and solutions
First of all, let’s find out why a monitor is unable to display anything when you start
the computer. Some of the answers are so evident I could
omit them, but still, I will mention each one. We’re going to start from the most obvious
causes and move on to more complicated issues. 1. The monitor is off
The first cause is that you forgot to turn the monitor on. Some monitors have their power button in the
front panel, and some have it on the bottom or even side edge of the frame. Quite often, you use the button only once
to turn the monitor on, and then just forget about it (because so many people just don’t
power it on and off every day, right?) If you press this button by mistake, the monitor
will be turned off. The solution is universal – just find this
button and press it to turn the monitor on. If it’s turned on, or nothing happens after
pressing the button, let’s move on. 2. Check the power cable
The second possible cause is a faulty power cable, or a cable which is not plugged in
at all. It’s very easy, either. Make sure the power cable is connected to
the monitor properly – or is it plugged into the monitor at all? Sometimes, all of us can displace the cables
accidentally, when doing some cleaning work or relocating things in a room, and it can
make the cable fall out of the socket. In most monitors, the power cable sits very
tight in the socket, so there’s always a chance that someone who plugged the cable
didn’t push it all the way in, and the cable may fall out. The solution is simple: try taking the cable
out of the socket and plug it in again as far as it will go. Also, examine the cable for any mechanical
damage, and check it with another device if possible. If the cable is all right and connected properly,
but the screen is black, let’s try something else. 3. Check the data cable
The third cause is the problem in the data cable that connects the monitor and the computer. Just as in the case with the power cable,
you need to check the data cable for proper connection, test it with another device, and
examine it for any mechanical damage. The matter is, you may think the monitor is
off, but in fact it’s on: however, there is no signal from the computer, so the monitor
shows only black screen. Check the cable, then. If this is an HDMI (the one with plugs looking
like those of a USB cable but a bit wider), disconnect both ends, then plug them in again. If your cable is of DVI or VGA type, tighten
the screws on both end of the cable; they are meant to hold the cable in place and ensure
proper contact. Some users neglect to use the screws at all
when they take the cable to connect a monitor and a computer, so there’s no surprise that
a cable may lose contact one day, leaving the owner to think: why on earth has the monitor
turned to black? If this method doesn’t help, let’s check
it for another issue. 4. Static
The fourth cause is the static electricity. Sometimes it can make the picture disappear
from the display. Try to disconnect ALL cables from the monitor,
including sound cables (if your model has built-in speakers). For some time, leave the monitor disconnected
from any other devices or power sockets. By the way, this trick may help when a computer
doesn’t start. Just disconnect all cables from the system
unit for some time. After a while, plug all cables back as they
were, and try turning the computer on again. 5. Display Resolution. The fifth cause is trying to set a wrong display
resolution. Quite often, if you try to set a higher resolution
than the monitor can support, the screen becomes black though the computer keeps on running. If the monitor doesn’t switch to the resolution
you need, boot the computer in the safe mode and try a lower resolution. After the restart, everything should work
properly. To boot a PC in safe mode, press and hold
the Shift button while the operating system is booting. All that being said, modern versions of Windows
will restore the original resolution within 15 seconds unless you click the button “Save
changes.” Even more, Windows usually detects the highest
resolution your monitor can support and shows you only compatible settings. 6. Monitor settings
The sixth possible cause is the monitor settings Make sure that the input settings are correct. Most monitors detect the input signal source
automatically, but sometimes this function may be disabled. Open the settings menu on your monitor, and
select Input. Select the input source you are using at the
moment, for example, VGA, HDMI or other. Otherwise, try to reset the monitor to factory
defaults; if you don’t know how, search the Internet for step-by-step tutorials. Usually, it takes pressing and holding one
of the control buttons. One more thing to mention is the refresh rate
(Hz) If your monitor supports 144 Hz, most likely
the HDMI itself can’t handle it. The matter is that the latest HDMI version,
2.1 dated the 4th of January 2017, can only work with 120 Hz! To be on the safe side, use a DisplayPort
cable for any configurations. 7. BIOS settings
The seventh cause is wrong BIOS settings. If you modified some BIOS settings recently,
and then encountered problems with the monitor, it could be the actual root of the problem. Try to remember what exactly you changed and
get the settings back to their old values, or reset BIOS to defaults. Visit out channel for detailed video tutorial
about it. Check the link below. Try disconnecting the computer from the power
outlet, press and hold the power button for several seconds, then turn the computer on
and see if the monitor works properly. Before proceeding to other methods, test your
monitor with another computer, a desktop or a laptop. If the monitor shows you the picture as it
should, then the problem is in your computer, and not in the monitor. 8. Graphics card
The eighth cause is the graphics card which can be either installed incorrectly or out
of order. First of all, let’s check if its sits firmly
in its slot. Turn off the computer, disconnect its power
cable and open the side cover of the system unit. Examine the graphics card. You can skip this part if your computer has
integrated graphics, that is, it’s not inserted into the computer as one of its components,
but is a part of its motherboard or processor. So make sure that the discrete graphics sits
properly in its slot, and if you doubt it, press on it to put it back where it belongs,
but without too much effort. If it moved and now sits as it should, you
need to tighten the screw that fastens the graphics card to the back of the system unit,
and if this screw is missing, find a new one to fix the graphics card in place. If the graphics card is out of order, most
computers would emit a beeping sound. The combination of sounds differs depending
on the motherboard manufacturer. So if the monitor is black and the computer
is beeping, most likely, there is a problem with its graphics card. You should either replace it or try taking
it out and plugging the monitor cable into the connector of the integrated graphics (if
your computer has it). Another component to be checked is the system
memory, or RAM. 9. System memory
The ninth cause is faulty system memory. If the screen is black and the computer is
beeping, one of the versions is your system memory conked out. So if the monitor won’t turn on and the
computer is beeping – check the graphics card in the first place, and if nothing changes,
check the system memory. Your task is to take out a RAM module, one
at a time, and try turning the computer on again, then repeat these steps for another
module (if you have two or more). ATTENTION! You must remember which slot a certain RAM
module was in; the point is that depending on memory characteristics, some modules may
need to be installed in a certain order, and if you change that sequence, the computer’s
performance may be reduced, or it won’t be able to start at all. If you took out one RAM module, and the computer
starts all right, then try to put the remaining module into the slot where the first module
used to be. If the computer starts again, then the module
which is out is the faulty one. If it doesn’t start, then there is a problem
with this specific memory slot. If nothing changed after all these actions,
you have to visit a service shop. The final point is good for those who know
a bit of electrical engineering. 10. The monitor’s power supply
The tenth cause is a faulty power supply of the monitor. Fixing this problem is the most difficult
of all, and it’s not a kind of task that everyone can handle. You need to take the monitor apart and find
the power supply. If necessary, you can take it out. If there is a fuse on it, check if it’s
working. If the fuse is all right, examine the capacitors. Replace any capacitors which are deformed
or swollen. Now put the monitor together, plug the cables
into their proper connectors, and turn it on. If you don’t have any experience in repairing
such things, contact a service shop. If none of the things mentioned in this video
helped you, and the monitor doesn’t turn on, it will have to be replaced. Summing up, I would like to say: no matter
what happened – don’t hurry, don’t worry, don’t fuss – just stop for a minute and
think why it could happen. Always try all ways of fixing the problem
on your own, I mean easy solutions, and only if they don’t work, go to a service shop
or look for a replacement. If you happen to know any other causes of
this issue and how to fix them, you are welcome to share this experience in comments under
