An unexpected power cut following the PSU replacement worked out, then everything functioned normally afterward.
Once I finished setting up my power supply, I powered on the computer and let it run for a short time. Everything looked fine at first, but after a few minutes it suddenly stopped. Since I wasn’t connected to a monitor, I’m not sure what caused it, but checking the event viewer revealed something unexpected. The only unusual action I took was booting up by jumping the motherboard and removing one fan because I needed a new Molex for a 3-pin connection. I also ran CPU, GPU, and stress tests, played games, and my PSU still seemed to function, though I remain concerned. Another strange occurrence was that my motherboard only recognized one RAM stick. This happened recently, so it’s unclear if it’s linked to the shutdown. After reinstalling both sticks, everything worked properly. I had an XMP profile enabled in BIOS before replacing the PSU, but it was disabled afterward, and all other settings were reset. My PC booted slowly, which worried me, so I ran the SFC utility and found some data corruption that appears to have been fixed. I’m unsure what’s happening and feel anxious because of that random shutdown. I don’t want to return the PSU for warranty since I think it might be due to a short when I was jumpstarting the motherboard—or something wrong with the RAM. Here are my details: OS – Windows 10 Home 64-bit Motherboard – MSI H310M PRO-VDH (MS-7B29) BIOS Version 7B29v1B CPU – Intel Core i5-9400F GPU – Zotac RTX 3060 Ti LHR PSU – Corsair RM Series RM750 Fully Modular Ultra-Low Noise ATX RAM – Team T-FORCE VULCAN Z 32GB (2 x 16GB) 288-Pin PC RAM DDR4 3200 (PC4 25600) Desktop Memory Model TLZGD432G3200HC16FDC01 HDD – Samsung SSD 860 EVO 500 GB
Ensure the RAM is seated correctly while the PSU is turned off. It’s simple—start memtest64 on a bootable USB, run it 8 times overnight. Install Speccy, verify the temperatures. Configure fans in BIOS and GPU drivers.
if this doesn't happen again its nothing to worry about. on my old build after i oc the ram it crashed the next day, once and never again... probably was indeed something with your ram, make sure its seated properly but other than that, if it doesn't happen again it's fine.
Completed 8 memory tests with no issues found. The system appears stable. Likely RAM problem caused by XMP enabled in BIOS. Consider disabling XMP during PSU replacement to avoid future concerns. No further action needed unless the issue recurs. No other solutions available without replacing the PSU, which would be costly.
