System abruptly powering off unexpectedly.
System abruptly powering off unexpectedly.
I recently upgraded my system yesterday. I’m using the 5700XT reference model (Asus) with two 8GB DDR4 RAM modules at 3000MHz. The setup includes a 700W 80 Plus Bronze semi-modular power supply, a 144Hz Benq 24" monitor. At first, the PC would shut down unexpectedly, especially after playing Doom Eternal. These crashes were random, often occurring after hours of gameplay or just a few minutes into the session. I checked everything thoroughly but found no clear cause. I adjusted the VGA settings and confirmed junction temperatures stayed below 88°C. The shutdowns continued only during Doom Eternal, not in other titles like Elden Ring, Street Fighter 5, Overwatch, or CoD Warzone. It seems to happen more when launching Cyberpunk. I didn’t notice any issues with the CPU or cooler after changing it. Testing various games showed similar problems—PC would crash right after loading maps or entering game menus. I tried resetting storage, updating drivers, and tweaking settings like VSync and refresh rates, but the issue persisted. Now I’m unsure what’s causing it—possibly a software glitch or a hardware quirk. The system runs cool, but performance drops when games start rendering 3D. I’m still trying to figure out the root cause and need advice on next steps.
What temperatures are being recorded while gaming? Such shutdowns might result from the CPU overheating, preventing the PC from adjusting via throttling. Often it's due to the power supply. Do you have a PSU available for testing?
When shutdowns occur during gameplay, 3D rendering typically pauses until the issue arises. Temperatures rarely hit the 60s, so there’s little time for that. I’m not sure about another PSU to test since I was planning to purchase a new one, but I wanted to check other options without spending money. My office computer has an old 650W seasonic, which could cause problems for testing. I’ll need to find a solution if I can’t locate alternatives. What suggestions do you have?
It was the PSU team, folks... The Seasonic 620W from early 2015 is performing great, the system runs smoothly and consistently. The Gigabyte PSU had issues right from the start, likely contributing to one motherboard failure... A lot of headaches! Thanks for all the feedback. P.S.: Could a PSU cause permanent damage if it fails protection features? I recall the first PC in the office using this PSU died after a storm, but it looked okay at the time and still works. Now I’m wondering if it might be stable enough to handle overvoltage from the grid...
