PC (monitor) shuts off after 5 minutes of gaming

Everything seems fine normally—I can browse the web, stream shows, or watch movies without any issues. Last year, I downloaded Dragon Age: Origins and played it briefly, but I didn't really get into it at the time. Now that I'm actually in the mood to play, I try to launch the game, but after about five minutes, the screen just goes black. The indicator light changes from green to yellow and then red, though the computer itself stays running. A friend suggested my graphics card might be dying on me, but maybe you all know a bit more about what's actually going on here. 🤷🕺🙂

Your friend makes a pretty solid point. Honestly, there's a 99% chance this whole mess is tied to your graphics card. To start, maybe try opening up the case and using some compressed air to blow out all the dust—it sounds simple, but if that GPU is running way too hot, it can definitely cause issues with your display. You could also try a clean reinstall of your drivers just to rule that out. If none of that works? Well, the ultimate test is to pop that card into another PC. If it acts up there too, then you know for sure the card is officially ready for retirement.

Larry Ortiz5 said:Your buddy is spot on. Honestly, this feels about 99% like a GPU issue. For a quick fix, try opening the case and using some canned air to blow out the dust—if the card is overheating, that’ll definitely mess with your image. You could also try a clean reinstall of your graphics drivers. If none of that works, the ultimate test is to pop that card into another PC; if the same thing happens there, then yeah, it’s time to say goodbye to that card.

But why would this happen? It's just a mid-range setup.
-Intel Core i7 955 Proc 4 CPUs ~3.2 GHz
-8 GB RAM

GPU:
-NVIDIA GeForce GTX series, I think it's 1 GB—it's a decent enough machine for now; nothing crazy, but it was solid five years ago... and now the video card is dying on me. I'm looking at spending maybe $110 right about now to replace it. 🤦

It doesn't really matter how powerful the rig is or how much you've put it through the wringer 😁 It just happens—kind of like when you're driving your car normally and then out of nowhere, a headlight just burns out.

Try what I suggested; honestly, it might just be an issue with your NVIDIA GeForce GTX series drivers.

It is highly probable that your graphics card heatsink is choked with dust. The fan's airflow effectively pulls debris directly into the cooling fins. I would suggest pulling the card out and taking it to a local gas station; you can use their air compressor to blow it clean. It is unlikely that your GPU has actually failed; this is simply the standard safety mode triggered by overheating. As Larry Ortiz5 previously suggested, you might even consider cleaning the entire PC...

If you're already planning on doing some maintenance, you might as well go all out and clean the entire rig. Just be careful with the graphics card; you don't want to accidentally damage anything while you're scrubbing away.
btw, it’s also possible that your GPU resources are just too weak for this game, which could actually be causing the overheating—especially if you're pushing it hard at 220 FPS.

Furthermore, it is entirely possible that your graphics resources are simply insufficient for the game, which can lead to overheating—especially if you are pushing it at a constant 220.

👍 whether it is underpowered or just plain inadequate.
