Quick Checks (fix 80% of issues)
- Restart the PC and your game/launcher. Then try again.
- Fully power down (shut down), switch the PSU off for 30 seconds, then power up.
- Check cables: monitor on the graphics card (not motherboard), both ends seated.
- Remove any recent USB dongles/hubs and test again.
- Roll back a recent Windows or GPU driver update (see guides below).
- Verify/repair game files in Steam/Epic/EA.
- Check temps (Guide below) — high temps can cause throttling/crashes.
Tip: If an issue started right after an update/driver/install, undo that change first.
