Spec posted below.

Problem: I am not getting video feedback/signal on the monitors.

I upgraded my 1080 gtx graphics card to 4080 rtx graphics card. Day 1, It worked fine for 9 hours and Day 2, it worked fine for 12 hours. Day 3, It was getting high temperatures so I decided to do some cable management and improve airflow. Now I am not getting any signal on the monitor. I can't access the BIOS configuration screen without video feedback on the monitor.

Motherboard is receiving power. Water cooler is receiving power. Graphics card is receiving power and ofc monitors are receiving power.
USB devices (mouse and keyboard) not receiving power.

I tried using the CLR_CMOS button to reset BIOS but nothing changed.
