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
