Computer shutting down unexpectedly!
Computer shutting down unexpectedly!
Hello! I’m experiencing some problems with my PC—it keeps shutting off and turning back on without any error messages. This issue started after I installed a new motherboard and CPU, about a week ago. I also replaced my RAM and performed a memory test without any issues. I thought the power supply might be the problem, but it didn’t affect the situation. The cables were swapped, and I updated all BIOS settings. I even unplugged the power cables to the power button, assuming it was a loose connection, but the problem persisted.
During this time, my CPU and graphics temperatures remain around 40-50°C. The issue occurs while running games or just browsing YouTube. I’ve double-checked that everything is properly seated and the thermal paste is still in good condition.
Here are the details of my setup:
Motherboard – Asus ROG STRIX B550-F GAMING ATX AM4
CPU – AMD Ryzen 9 5900X 3.7 GHz 12-Core
RAM – Corsair Vengeance RGB Pro 32 GB (2 x 16 GB) DDR4-3600 CL18
AIO – Corsair H100i v2 70.69 CFM Liquid Cooler
Graphics Card – Asus TUF GAMING GeForce RTX 4070 Ti 12 GB
SSD – Samsung 970 Evo 500 GB M.2-2280 PCIe 3.0 X4 NVME
PSU – Corsair RM850x (2018) 850 W, 80+ Gold Certified, Fully Modular ATX
Case – Phanteks Eclipse P360A ATX Mid Tower
Additionally, I have a 1TB Seagate hard drive in the M.2 slot.

My usual recommendation with an unstable new build is to return everything to stock speed.
If you are overclocking your memory with XMP/EXPO/DOCP, disable this setting in the BIOS. Running your Vengeance RAM at 3,600MT/s might be the cause of instability. When you switch off XMP, your memory speed should drop back to the more stable DDR4 JEDEC default of approximately 2,133 or 2,400MT/s.
If you are overclocking your 5900X with PBO (Precision Boost Overdrive) or Ryzen Master, etc., switch off this setting to reduce boosting.
If you are overclocking your RTX 4070Ti with MSI Afterburner, etc., disable it.
When you tested your RAM, did you try booting the PC from MemTest86+ on a USB memory stick? This is a more thorough test than Microsoft's. Allow MemTest to complete at least one full pass (taking 1 to 2 hours).

Do you have your two DIMMs installed in the two slots recommended by Asus in their user guide? The default tends to be slots A2 and B2 (second and fourth slot away from the CPU). Fitting the RAM in A1, B1 can lead to a slightly less stable system at maximum XMP frequencies. Check your user guide.
