Why games on my steam account don't work?

Hello Duru Zeren,

Thank you for reaching out to the Microsoft Q&A Forum! Apologies for any inconvenience you're experiencing. The behavior you described usually points to a graphics driver hiccup (Windows briefly reset the display after a crash), and here's how you can fix it:

1 - Go to Settings → System → Display → Scale & layout and set Scale back to 125% (or 100% just to test), and make sure Advanced scaling settings has custom scaling turned off.

2 - Launch one game in a “safe” mode

• In Steam → Library → right‑click the game → Properties → General
• Disable Steam Overlay, then in Launch Options add: -windowed -noborder

3 - If games still crash, clean install your graphics driver

Uninstall the current driver:

• Device Manager → Display adapters → (your GPU) → Uninstall device → check Delete the driver software (if offered).
• Install the latest official driver from your GPU maker (NVIDIA, AMD, or Intel).
• Temporarily turn off overlays (NVIDIA/AMD, Discord, MSI Afterburner/RivaTuner).
• Reboot and re‑test a game.
