Random shutdowns
Random shutdowns
Hey, I've noticed my PC tends to shut down under specific conditions while playing certain games. It doesn't show a blue screen but just a black screen, and it varies—sometimes right after loading and other times later on. The issue seems linked to the parts you mentioned: Intel i9-9900K, ASRock formula, AMD RX 6900 XT, OCF Asus Rog Maximus XI, 32GB RAM, 3000Hz, Vengeance 4x8, and NZXT X53.
Have you verified the temperatures while gaming? What power supply do you possess? How recent is it? Are you adjusting any overclock settings manually? It's odd that the system would power down during high load, which doesn't seem like a Windows or software issue. Otherwise it would typically display a blue screen and restart. If you're not overclocking and temperatures are normal, I'd begin diagnosing. If you have functional replacement components or a colleague with backups, I'd start by checking the power supply.
I own an MSI MPG A850G 850 watt 80 Plus Gold power unit. Temperatures vary between 50 and about 80 during peak usage, especially when crashes occur in certain games. This suggests it might not be a power supply problem since I managed to play Elden Ring for up to three hours at a steady 60fps without any issues. When I try an indie plane builder game that's 1GB, I can run at 1000fps and crash after ten minutes. I haven't overclocked anything and only adjusted the BIOS settings—specifically the XMP profile and disabling the ASUS feature that limits Intel performance (called "Asus multicore enhanchment"). Using a Riva tuner helps me maintain higher FPS, allowing longer play sessions without crashes. My hardware is around two years old, and the power supply seems newer than the CPU.
It's hard to know where to begin. What's the GPU temperature while playing? You need to start somewhere to check issues and eliminate parts. Test with another graphics card on your PC and then on a different machine. Keep checking each component individually.
I completed some tests and it looks like your GPU is constantly overheating, especially in games like BeamNG and Sniper Elite 4. The temperature spikes quickly, jumping to 100°C right away. For Sniper Elite 4 the max I reached was 81°C, so you're not alone in this issue. You might want to check your thermal paste or consider better cooling solutions. Since your room isn’t well ventilated, adding more fans could help, but make sure they’re placed properly. Other tips include cleaning dust from vents and using a higher-quality cooling system if possible.
You can likely use the Kryonite Thermal Paste you already have, but make sure it matches your CPU model. If not, consider buying compatible thermal pads. For guidance, look for clear tutorials on replacing thermal paste safely—avoid damaging your 6900XT.
