New PC suddenly stops my games quietly, going straight to the desktop without any reset or error display.
Hello, I’d like to explain that I just assembled a new PC, and so far it’s functioning well for programming and various tasks. However, I’m encountering difficulties when gaming. Whenever I launch a game—whether it’s light or heavy, like Elden Ring and DOTA 2—I experience the same issue. After a few minutes, the game crashes, sometimes taking a bit longer but always ending abruptly. It doesn’t shut down completely; the PC remains operational for all these days.
Details about the build:
- Motherboard: ASUS ROG STRIX B650E-F GAMING WiFi
- GPU: RTX 3090
- CPU: Ryzen 9 7900
- RAM: Team DDR5 32GB (2x16GB) at 6400MHz (without DOCP, running at 4800)
- SSD: M.2 Corsair MP510 480GB, 3480MB/s NVMe PCI-E x4
- Power Supply: ASUS ROG THOR 850W 80 Plus Platinum
I’m trying to figure out what’s causing the problem and whether any tests are needed. I found it strange since the PC is working fine otherwise, just games crashing to the desktop. I’ve read many similar posts but haven’t found a clear solution. The GPU was replaced, yet the issue persists. I checked my PSU specs—it shows a maximum of 550W during gaming in ultra mode, and I can’t easily upgrade to another 1000W without risking damage. My calculations suggested 850W would be sufficient, but I still have no idea what to do. The games run smoothly and load well, only crashing unexpectedly. It’s not a driver problem either; I’ve enabled all DMA options and even tried older drivers from last month. Temperatures are normal (CPU 40-50°C, GPU 69-73°C).
Any suggestions would be appreciated. :/
Welcome to the forums, newcomer! What BIOS version is your motherboard running right now? Where did you get the game installers from? Regarding your RAM, if you're using the latest BIOS, try enabling D.O.C.P/X.M.P and check if stability improves. I don't have much of a budget for another 1000w PSU just to test... any suggestions? You should ideally be using a 1KW PSU, which is designed to reliably power the RTX3090. You could borrow a donor PSU instead and see if the problem continues.
