Hi there,
Is there any error codes on the motherboard, such as a digital code, or an LED next to components, etc? Having that may narrow down what is causing the issue. Also, is there a physical OC Genie button on the motherboard as well?
My suggestion would be to clear the CMOS again, and start the PC in a simplified configuration for the first time. To do that:
- Turn PSU off, unplug PC.
- Press the power button on the PC (to drain capacitors).
- Take the CMOS battery out and wait for 5 minutes.
- If you have a dual channel memory kit, (or multiple kits), remove all of the RAM modules except for 1.
- Uninstall the GPU and plug your monitor into the motherboard port (CPU integrated graphics)
- Unplug your SSDs/HDDs
- re-insert the CMOS battery.
- plug PC in, turn on PSU
- Try to boot the PC and get into the BIOS if possible.
If that works, you can shut the PC down, turn it off, and reinstall your components, the BIOS should detect the changes again. Hope this helps
