PC Shuts Down While Playing Games in Fullscreen
PC Shuts Down While Playing Games in Fullscreen
Here’s a rewritten version of the text, aiming for clarity and conciseness:
“My high-end PC (specs detailed below) experiences sudden shutdowns when running games in fullscreen or bordered fullscreen mode – specifically during gameplay, not menu navigation. It works perfectly fine in windowed mode. I've ruled out overheating by monitoring CPU and GPU temperatures, which remain consistently below 80°C. My Seasonic Prime 1500W PSU is also new and high-quality.
Strange symptoms for sure. My son had a similar problem but we never tested windowed so it might not be the same cause as yours. Usually overtemps cause throttling which leads to frame rate loss in my experience. Your situation seems to be power related . He had an Ultra brand 1000watt supply. We changed it and it fixed the problem. I dont know how old your system is but it's certainly a possibility that your power supply may be faulty as well. I'd check all my connectors first. MB 24 pin and 8 pin especially. It can be easy to think they are completely inserted. If all that checks out maybe you could borrow a supply to test with. A 600 watt seems large enough for what you're running. Good luck to you sir. I hope this helps
