Question PC has stopped sending signal to my monitor ?

Jul 24, 2022
I recently got an AIO cooler which came to replace my ryzen cooler, after this my PC wouldn’t give a monitor signal, later the CPU and motherboard became faulty so I bought a new pair.

With this new CPU and motherboard I was hopeful that this issue would pretty much alleviate itself but no I still have 0 signal being output to the monitor. I already tested two GPU’s and confirmed it was functional. I tested the videos cables and they were also functional. All that appears now is a red light over the CPU label on my new motherboard and I’m clueless on what the issue could be since all of it is new, plus this was a persistent issue on my last CPU and motherboard.

I’m really desperate and tried many different solutions:

  • Checking the cables connecting from the PC to the monitor, they work.
  • Switching out graphic cards, nothing changed
  • Re-seating RAM in different DIMM ports, nothing
  • Trying only one stick of RAM, nothing
  • Cleaning the RAM sticks, nothing
  • Resetting CMOS battery, nothing
  • Putting back my old Wraith cooler, nothing.
Just waiting for anything to pop up on my monitors, but nothing.


Board: B550 Tomahawk Max Wifi
