Said friend of mine told me this could have to do with 2D–3D switching (or something like that), but I did not understand much of what he was saying. Should I turn the monitor on after turning on the PC first, the PC would freeze. That is, if I turn the monitor off and on while the computer is asleep (or hibernated, or completely turned off). The freezing always starts to occur only after I’ve actively used the PC for some time.įurthermore, if I put the computer to sleep or hibernate it (or, logically, if I turn it off altogether), I can safely turn the monitor off and on again and then turn on the PC and everything works without problems. For example, if I turn the PC on and the OS loads, I can turn the monitor off and on again as many times as I want and the computer doesn’t freeze (provided I do this immediately after the OS initially loads). What is also worth mentioning is that this freezing does not occur immediately after I turn the PC on. The graphics card is an RTX 2080 (MSI GeForce RTX 2080 SUPER GAMING X TRIO to be precise). It is a 31.5-inch one (BenQ EX3203R), it is connected through a DisplayPort cable directly to the graphics card. I bought the monitor together with the PC. Therefore, it is extremely difficult for me to diagnose where the problem lies. Event Viewer shows a record of the PC being turned off the hard way, it says something along the lines of "The system was not shut down properly", but it doesn’t give me any specific information that would point to the root cause. I have no choice then but to reset my PC using the "Restart" button on the PC case. After I turn it off, the PC is still responding to user input (for example, if I press the "num lock" button on my keyboard, the corresponding light switches off, etc.), but as soon as I turn the monitor back on (even if I do so a few seconds after turning it off), the PC freezes (I can tell it has frozen by looking at the PC’s status in TeamViewer, which I use to remotely access my PC and use it for work – it shows up as offline in TeamViewer or if I press the "num lock" button, the corresponding light does not respond to that – it doesn’t switch off anymore), and the monitor shows the error message "No signal detected". Until I turn it off, everything works with no issues. The freezing occurs when I turn off the monitor and then turn it on again. Until recently, everything worked just fine.

It was very expensive, I chose the components with the help of a friend of mine – a developer (IT guy). My PC is extremely powerful, I bought it about a year ago.

I am not sure if "Internal Hardware" is the right category to post this, as I’m not sure this is a hardware issue (it may be a matter of "wrong settings"). I am new to the forum, so let me say hi to everyone!
