Desktop board DQ965ss / DG965GF has a red light when switched on. Can anyone help. Remember, no display, but the CPU fan turns on.
As per the motherboard Technical Product Specification, the red light located near the memory slots, will be lit if the memory slots are powered.
As part of troubleshooting steps, I recommend you testing other monitor with different cable and make sure cable is not loose.
Also, you can try taking the motherboard outside of the chassis to discard grounding issues. Testing other hardware on the motherboard such as processor or other memory part number may do the trick.
