6. Troubleshooting

This section addresses common issues you might encounter.

• System Does Not Boot:
  • Check all power connections (24-pin ATX, 8-pin CPU, GPU power).
  • Ensure RAM modules are correctly seated.
  • Verify CPU installation and cooler connection.
  • Try booting with minimal components (one RAM stick, one GPU) to isolate the issue.
• Graphics Cards Not Detected:
  • Ensure GPUs are properly seated in their slots/risers and have adequate power.
  • Access BIOS and verify that all PCI-E slots are enabled.
  • Update graphics drivers to the latest version.
  • Remember Windows operating system limitations for multiple GPUs (maximum 8 AMD or NVIDIA GPUs).
• BIOS Reset: If you encounter issues after changing BIOS settings, you can reset the BIOS to default settings. This usually involves clearing the CMOS by removing the CMOS battery for a few minutes or using a dedicated jumper on the motherboard.
