Hi there! My name is David. It’s a pleasure to help you today.
When your PC stops working, does any message or error appear on the screen?
Could you tell me in which game the problem occurs?
Does it only happen when you have Discord and the game open?
If your system uses half of your RAM without any visible program open, this usage could be within the normal RAM usage range, considering the operating system’s usage. However, it is necessary to check if there are applications or background services that might be using RAM.
When a game is running, the system frees RAM if necessary and reduces the priority of other processes so that the game can have more resources available.
Please check which applications start with the system:
Open Task Manager > Click on "Startup Apps" > there disable the ones you don’t need. Right-click on the application and then click Disable.
Let me know if the shared information has been helpful. Regards.
