Bootloop or power loss problems after PC upgrade, but stable once operational.
Bootloop or power loss problems after PC upgrade, but stable once operational.
Hey everyone, I recently made several upgrades to my computer—new motherboard, CPU, RAM, and power supply. But now I’m facing a strange issue: after a short period of inactivity (usually just before turning it on), the system gets stuck in a boot loop. It powers off completely, then restarts itself without any error messages. This only happens when the Windows loading spinner appears, even though I don’t see any problems in the BIOS screen. Once it passes into automatic repair mode and then a final reboot, things seem normal. I can play games, watch videos, run stress tests with OCCT, and even write this post. If I just restart the PC or leave it off for a bit, it boots up straight away. Despite all my troubleshooting, I’m still puzzled about what’s causing this problem. I’m leaning towards the power supply unit or motherboard, but before I order a replacement, I want to double-check. Could anyone else have any insight?
I encountered issues with my Corsair Vengeance 5600 CL36 setup. The stick in slot B2 failed repeatedly over several months, even after replacing most parts except the power supply and SSD. I’m now using a different brand’s kit, but XMP settings aren’t reliable. The new system tends to shut down immediately when the debug LED flashes DRAM, though it works afterward. Edit: 4 sticks are less stable at the same speed compared to 2 DDR5 sticks. It’s quite sensitive. Edited October 23, 2023 by DreamCat04
You've been experimenting with the BIOS settings and CMOS reset, trying different approaches to stabilize your system. The behavior you're describing—unstable after changes but working after a short wait—suggests possible hardware issues or BIOS configuration problems. It's worth noting that some users report similar issues with specific motherboards or chipsets, though it can vary. If you're unsure about the hardware, consider checking for common failure points like power delivery, fan control, or storage health.
