I've been assembling my own PCs since the early 90s, but I'm currently facing a problem that requires your assistance.
I've been assembling my own PCs since the early 90s, but I'm currently facing a problem that requires your assistance.
My problem is outlined below and any help would be greatly appreciated since I'm unable to locate a solution.
Every day after turning on my PC, it functions perfectly for durations ranging from 60 seconds to 30 minutes. Then the display becomes dark, though sound remains audible but distorted for a few seconds before the system restarts. There are no alerts or messages displayed on the screen.
Following the restart, the PC operates flawlessly and continues to run indefinitely until I power it off. What bothers me is that after restarting, it becomes completely stable—no interruptions, no crashes, and it performs tasks like browsing, playing games, or 3D rendering without any problems. I have performed standard stress tests, and everything functions normally; there are no overheating warnings or glitches.
I am certain my hardware is in good condition, and the issue seems to stem from Windows itself, though I may be mistaken.
Operating system: Windows 11
Motherboard: Aourus Master X670E
CPU: 7800X3D
GPU: RTX 3080
Power supply: Silverstone 1200w
RAM: Two DDR5 certified sticks, not overclocked, no overclocking applied at all (no XMP, PBO, etc.)
All storage is SSD-based, a mix of Samsung Intel and Corsair products. The motherboard supports multiple SSDs, but I do not use any SATA devices.
The unused PCI slots are empty, so there are no additional components like network or sound cards.
All drivers are current, including the latest BIOS updates.
What confuses me is that after this abrupt reboot, the PC operates perfectly—no issues, no interruptions, and it remains functional for as long as I want until shutdown. This unexpected stability has left me puzzled. I usually test stress conditions, but everything runs smoothly without overheating or glitches.
I would greatly appreciate any advice from readers who have more in-depth knowledge of Windows, as I suspect this might not be a hardware problem.
the PSU is their newest model released this year, with a manufacture date of August 2025.
Reboot immediately after the initial start-up doesn’t seem to resolve the problem.
CMOS was reset manually before updating the BIOS to erase any personal settings and restore everything to default prior to the update.
Additional details I wanted to note. If I turn off the PC for just an hour or two while going out shopping, it reboots without issues.
It seems the problem lies in the fact that the PC was shut down overnight.
I keep the power on, so there’s no manual switch-off on the PSU itself and the power cord remains attached to the wall socket. The power switch on the PSU is only used when I’m away from home for more than a day or two, such as visiting friends in another city.
EDIT
Additional information: I use HWinfo to monitor my system when necessary. All temperature and power readings are normal. The WHEA reports no hardware errors for Windows overall.
There’s no overheating or voltage fluctuations—effectively everything is functioning perfectly. This makes the issue difficult to pinpoint, leading me to suspect it’s related to Windows 11 rather than hardware.
Under regular use, the CPU runs at 48°C and today’s ambient temperature is 32°C. My GPU operates between 29-30°C when not gaming.
During gaming sessions, such as playing Dune Awakening, I reach 78°C on the CPU and 64°C on the GPU, though this seems irrelevant since these spikes happen only during intense usage, after which normal temperatures are displayed via my second mini screen with the sensor panel.
I would really appreciate receiving detailed troubleshooting information. Please download the SysnativeBSODCollectionApp, save it to your Desktop, and run it. Afterward, upload the generated zip file to a cloud service and provide a link. This app compiles all available troubleshooting data, simplifying problem diagnosis without collecting any personal information. It is trusted by many reputable Windows help forums, including this one. While you may not be experiencing BSODs, the data will still be valuable for resolving your issue.
You can review the contents of the zip file before uploading, as most files are text documents. Please avoid modifying or deleting anything. For a detailed explanation of each file, refer to the provided link.
I would concur with the power scenario that appears to resolve itself after the capacitors are fully charged. It might involve the motherboard or power supply capacitors, though I would favor the power supply.
I believe I might have resolved the problem using the SysnativeBSODCollectionApp shared by ubuysa. After reviewing many reports, I found an issue where browser hardware acceleration could affect the GPU and trigger an unexpected blue screen. Although I didn’t see a blue screen myself, the error code indicated one. I turned off the browser acceleration, shut down the PC, and left it off for about nine hours before it restarted normally without needing a reboot. I plan to check again after a night’s sleep to confirm if this fixed the matter.
I also acquired a Corsair 850w PSU from a friend who recently upgraded his gaming rig with a 50 series Nvidia board, including the necessary cables. This gives me an opportunity to test whether the problem is related to power supply issues, as some people suspect. I’m hoping it isn’t, but the PSU is still under warranty for another 14 months—so unless the capacitors are faulty, it shouldn’t cause any financial trouble.
There were abrupt shutdowns during long video transcodes after installing MSI Afterburner and setting a GPU power limit to 95%. The GPUs used were an RTX 3060 and RTX 4070 in a 7950X setup. Possible cause could be current spikes on the GPU triggering OCP.
