PC Gaming Issues Oct 16, 2026

Screen randomly goes black but the PC keeps running

Happens maybe twice a day, sometimes in games, sometimes just on the desktop. Sound keeps playing and the fans keep going, but the monitor says no signal until I restart. Already tried another displayport cable and a different port on the card. GPU dying, or is it something else?

Does it happen only in games, or on the desktop too? That's the quickest way to narrow it down. If the sound keeps going and the PC is clearly still running, it's the display side, not the whole machine. In rough order of how often it's the culprit: the cable (swap it, displayport especially), the GPU driver crashing and recovering (do a clean reinstall with DDU), and GPU power - check both PCIe connectors are pushed fully in. Games-only points at GPU/power; desktop too points at cable or monitor. A spare monitor or a different cable sorts it out fast.
