Many Windows 10 users complain of their monitors unexpectedly turning off while they are using their computers. For some of the users affected by this problem, their monitors turn off spontaneously while they are using their computers, whereas for others, the monitors simply go blank a short while after they boot their computers up. In all cases, affected users’ monitors turn off even though their computers remain on. Since they can’t see what’s happening on their screens, this is an extremely significant problems for all of the people affected by it.
If your computer’s monitor also goes blank and says something along the lines of it going into power saving mode or it no receiving any signals from your computer (or even if the monitor just goes blank and doesn’t say anything), you are a victim of this problem. This issue, in almost all cases, is caused by any one of three things – a poorly seated, faulty or dusty GPU, outdated or incompatible GPU drivers or a PSU (Power Supply Unit) that is either busted or isn’t appropriately connected to your computer. To fix this issue, you need to:
Make sure that your computer has compatible and the most recent drivers for your GPU. If you can’t get into Windows because your monitor turns right after your computer starts to boot up, see if you can boot into a Windows installation USB or DVD and if you can, clean install Windows 10 using the installation media. Once you have clean installed Windows 10 on your computer, make sure that you install the latest and completely compatible version of your GPU’s drivers. If doing so doesn’t fix the issue, move onto the next step.
Pro Tip: If installing the latest drivers for your GPU doesn’t get the job done, you should try installing various other drivers that you know to be perfectly stable.
Open your computer up and remove your GPU. Clean the GPU so as to get rid of any and all dust and other impurities on it and then firmly reseat it in its place, close your computer up and boot it and see whether or not the problem still persists. Also, make sure that your GPU is in full working condition and is not faulty. If the issue still persists, try the next step.
Open your computer back up and check to see if all of your PSU’s fans are running unhindered. If the PSU and its fans are working at their full capacity and are completely okay, remove, clean out and then firmly and correctly reseat the connections between the Power Supply Unit to your computer. More often than one would care to think, poorly seated PSU connections turn out to be the root of this problem.
