Here are our recommendations to narrow this issue:
- Place the board over a non-conducting surface and test it on a minimal configuration. No add in components and also proceed to test the system with minimum memory.
- Even though we know the power supply is working fine, we recommend testing with a different one just to narrow the issue.
-Check all the connections on the system.
- Clear the CMOS battery for 30 minutes and restore default settings in the BIOS.
