Why is my monitor losing signal when launching a game?

Saiushan Naidoo · Jun 29, 2023

Hi. Thank you for taking the time to read this. I’m having a bit of an issue with my gaming pc. Whenever I launch a game (eg. Fortnite) my monitor loses signal but my pc stays on. It only happens on heavy games like Fortnite and Genshin Imapact but there’s no issue when I run a game like Minecraft. So I thought it was a power supply issue since my power supply is 500w and my rtx 3050 recommends a 550w power supply. However I just discovered that when I decrease my monitors native resolution from 2560x1440 to 1920x1080, the games launch for a few minutes and everything seems to working fine until the monitor loses signal again. I’ve tried everything from updating the graphics drivers, cleaning and reseating RAM, reseating graphics card, uninstalling and reinstalling graphics drivers. I am confused whether it’s a power supply issue since Minecraft (a low powered game) can run fine OR it’s a resolution issue since the games can launch for a few minutes at a lower resolution but then the monitor loses signal. Please help me .

Specifications

Amd ryzen 5 3400G

ASUS dual rtx 3050 8gb OC

Monitor: ASUS TUF vg27aq 144hz

Power supply : FSP 500w

I don’t know if the resolution is changing when i launch the game. Maybe it changes to a very high resolution

Hello Saiushan, before trying the option A. I can suggest some possible solutions from the Windows side.

1. Open the task manager and go to the startup tab, once there, click "disable" on each app listed there
After that Restart the PC and see if the problem is solved

2. Do a clean boot in your Windows PC. For that please follow this article:

3. Start your PC in safe mode and try to run some games in that way.

Hi. I want to Thank you, Manuela and SwordofWhedon so so much for helping me out. I greatly appreciate it. Turns out that it was just a faulty psu which I did replace. I want to thank you so so much because I was really getting worried that my graphics card was broken. THANK YOUUU!!

Yes, please disable all the apps. You don’t need to worry about the app data, the clean boot only disables the automatic start-up of third party services.

Must I disable all apps for option 1!?

Would a clean boot remove all my app data?
