monitor goes black and restarts my pc when i try to play valorant

Hello, Saint Meow

Welcome to Microsoft Community.

I’m sorry to hear that you’re having trouble playing Valorant. It sounds like you’ve tried a lot of possible solutions, but none of them worked. I appreciate your patience and persistence. Based on the information you provided, I have some suggestions that might help you fix the black screen issue. Please note that these are not guaranteed to work, but they are worth a try.

One possible cause of the black screen issue is a conflict between Valorant and your antivirus software. Some antivirus programs may block or interfere with Valorant’s files, causing the game to crash or freeze. To prevent this, you can try temporarily disabling your antivirus software before launching Valorant. You can also add Valorant and its folder to your antivirus’s exception list, so that it won’t scan or block them. Remember to turn on the antivirus later.

Another possible cause of the black screen issue is a corrupted or missing game file. Sometimes, the game files may get damaged or deleted due to various reasons, such as power outages, disk errors, or malware infections. To fix this, you can try running the Riot Games Client’s repair tool, which will scan and repair any corrupted or missing game files.

A third possible cause of the black screen issue is an incompatible display mode. Some players reported that switching between windowed mode and fullscreen mode helped them resolve the black screen issue. This will allow you to switch between the windowed mode and fullscreen mode.

A fourth possible cause of the black screen issue is a problem with your DirectX version. DirectX is a set of software components that allow games and other applications to interact with your hardware, such as your graphics card, mouse, keyboard, and speakers. If your DirectX version is outdated or corrupted, it may cause Valorant to crash or freeze. To fix this, you can try updating your DirectX version to the latest one available for your Windows version.

Besides, some users have reported that Vanguard interferes with computer processes and can cause high CPU usage, leading to system freezes and restarts. You could try temporarily disabling Vanguard to see if that resolves the issue.

Some other possible causes of the issue include CPU overheating, a faulty power supply, crashes due to overclocking, or running out of GPU memory. You could try monitoring your CPU temperature and checking your power supply to see if either of those are causing the problem.

When I select a hight quality, the screen goes black for about 20 seconds while it's waiting for me to confirm the change, but since it is black I leave it. There's no message on my monitor, but it is still on rather than in standby. Then it returns to low resolution. The monitor only has one hdmi port, so I can't try a different one. I haven't tried a different cable yet, but the cable works perfectly with my laptop.

it just launches opens a black window for the game sometimes black screens the monitor like its trying to launch then it just closes out with no error messages or anything. then when you try to launch it again it says previous launch was unsuccessful would
you like to start in safe mode and it doesn't matter what option i click it does the same thing every time. it doesn't cause my pc to restart or cause any issues to my system it just wont let the game launch.

I've been having the same issue. Anytime I get a notification or achievement my screen goes black for a second or two then returns to the game and it usually does it twice every time while the monitor resets back to HDR mode. This not only happens with the
game bar but anytime my fullscreen game is interrupted, like when adjusting volume from my keyboard and the Windows volume UI pops up. It kicks my monitor out of HDR and screen goes black, comes back on, goes black again, then comes back on until the next
interruption. I'm assuming that's what is causing it at least. I am using the Dell S3220DGF monitor with HDR turned on.

Hopefully, they find a fix soon.

Very Respectfully,

Randall

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you with your concern.

I can see here that you're on PC, to clarify, is this happening when you're signing in to Xbox App? If yes, we may need to repair and reset the Xbox App by following the steps below:

"Settings > Apps > Installed Apps > Search for "Xbox" > Advanced Options > Repair > Reset > Restart your device."
