This updated setup shuts down unexpectedly even though it appears to function properly.
Details: Motherboard model Msi X670E MPG Carbon Wifi CPU Ryzen 7 7800X3D (PBO On) GPU RTX 4090 RAM 64GB GSkill Trident Z5 Neo RGB 6000 CL30 PSU Montec Titan Gold 1200 SSD Samsung 990 Pro 2TB OS Windows 10 Pro BIOS E7D70AMS180 build date 8/10/2023 Everything functions well until the monitor goes dark and shows "No DisplayPort signal". The machine stays on with RGB lights active but fans spin at full speed. After a short delay it restarts, displaying error codes b4 and 15 with the orange troubleshoot light. Eventually it boots normally to the Windows login screen. It lacks a consistent pattern, randomly restarting during gameplay or while watching YouTube, sometimes failing to restart at all and leaving the monitor black with fans running continuously. I suspect a power supply issue. Please let me know if you need assistance.
Considering it might be a power supply problem, the PSU is also new. Have you attempted using the Onboard Graphics to check if the issue persists? Reviewing Windows system logs could help pinpoint whether it's a software or hardware fault. Also, are you running any overclocking? If yes, have you reset everything to default settings and tried again? I recall a similar situation where the problem arose during game launch, with the GPU failing to set the required GPU power before the splash screen appeared, causing a crash despite a good PSU. Does this occur under specific conditions? The best approach seems to be reproducing the issue through benchmarks.
The PSU is new. I'll test the onboard graphics to observe the results. It doesn't appear to follow a consistent pattern; it restarts during gameplay or while browsing YouTube. Benchmarking was successful. The thermal readings are solid. I examined the Windows Event Viewer and noticed minimal entries overall, with no significant warnings in any category. However, under Custom Views > Administrative Events, there were numerous errors and alerts. My computer unexpectedly restarted around 3:38, coinciding with a surge in errors at that moment.
