Question What are the possible causes of computer restarting after booting ?

[6uin]

I recently built a PC and noticed a slight issue with it.

Every other day (at least that's what I've observed), when I start it up, the computer boots, but it seems slightly underperforming (minor system lag, as if it's struggling a bit). After about two minutes, the monitor screen goes black (no signal detected), and the PC restarts itself. After the restart, it runs perfectly fine all day. I play games, stress test it under maximum load, ran all benchmarks in 3DMark, plus the Stress Test over few times (OCCT + 3D Mark), and there’s not a single issue!

Where could the problem be?

My setup:

• CPU: 9800X3D
• Motherboard: MPG B850 EDGE TI WIFI
• GPU: MSI RTX 5080
• RAM: ADATA XPG Lancer Blade RGB, DDR5, 32 GB, 6000MHz, CL30
• Storage: SSD Kingston Fury Renegade 2TB M.2 2280
• PSU: Gigabyte Aorus Elite P 1000W 80 Plus Platinum ATX 3.1
• Windows 11 24H2

Additional notes:

• I have Fast Startup (Windows option) disabled
• Fast Boot in BIOS is disabled
• RAM is set to EXPO 1 profile (from 4800 to 6000 MT/s)
• I have the latest BIOS installed

Other BIOS settings:

• Global C-state Control: Auto
• Power Supply Idle Control: Auto
• ErP Ready: Disabled
• Wake up Event by: BIOS

Today, I changed these settings, but I'm not sure if it will help:

• ASPM Control for CPU PCie: Disabled
• Memory Context Restore: Disabled
• Global C-state Control: Disabled
• Power Supply Idle Control: Typical Current Idle

over heating

How so? During tests and gaming, the components do not exceed 60 degrees Celsius, especially at startup when the computer is turned on.

test with only using the igpu?

Have you run MemTest86 on your RAM?

If a complete run of MemTest86 results in zero errors, grab a cheap SATA or M.2 drive and perform a clean install of Windows with your normal boot drive unplugged. This will help to prove if the fault is software or hardware related.

I ran a memory test with the MemTest program. It lasted over two hours, completed 4 full cycles, and ended with the message 'pass' – zero errors. It’s worth mentioning that before the test, I changed the Memory Context Restore option in the BIOS from Auto to Disabled. Of course, I still have the EMPO 1 profile enabled. Let’s see if turning off Memory Context Restore helps. I will keep testing. Unfortunately, I don't have a second SSD on hand – I would have to buy a new one. 😕

[...]with your normal boot drive unplugged

Is there a way to disconnect the M.2 drive without removing it from the motherboard?
