Occasional PC restarts
Occasional PC restarts
You're experiencing intermittent shutdowns without a BSOD, with the screen going black while fans spin and USB devices disconnecting. It occurs randomly across both Windows 10 and Linux, sometimes during gaming and other times when you're not using the PC at all. Your setup includes a Ryzen 1800X, 16GB Corsair RAM, an Asus X370 motherboard, GTX 1070, and a Silverstone power supply. You've already tried replacing the motherboard and applied an XMP profile to your RAM. The issue seems linked to power delivery or possibly the PSU itself. Start by checking the power supply's output stability—look for consistent voltage under load. Also verify that all cables are securely connected, especially USB ports. If the problem persists, test with a different PSU or monitor the system logs for error codes.
It seems you're right about the suspicion. Review your Event Viewer logs to ensure there aren't any Critical or Error events beyond "recovered from loss of power." If you don’t have a UPS, consider getting one. Assuming your 550W unit is outdated for today’s standards, it may be becoming less usable despite its specs. Seasonic Focus Gold PSUs are affordable and dependable. For further advice, check the latest PSU tier lists.
Suggests checking PSU or motherboard connections first. Recommends gently tapping DIMM slots, GPU ports, and cables to confirm they’re snug. Mentions the 5900X issue has improved after this step.
I didn’t realize PSUs were completely gone. I was hoping I could hold this through until the end of time, haha. I’ve already tried reseating everything and pushing cables, but it’s not helping.
They can definitely fail in several ways. The most subtle and annoying is when capacitors degrade. This leads to unpredictable behavior during power-up since they lose stored current before the next surge, making shutdowns worse over time. In some cases, repeated attempts to restart might actually replenish enough charge to get things going again.
