i recently changed my CPU from the ryzen 5 5600G to the ryzen 7 5800x, and the fans are all working except my GPU meaning the GPU isn’t working and my screen says no signal. My mother board is the HANA REV-B and my GPU is the RX 6600xt.
Ive searched everywhere and i cant find a solution, is it my gpu, cpu, motherboard??

Greetings @chr16
Welcome to the HP Forum.
I can't locate a Hana Rev-B MB.
The Hana MB supports a Ryzen 5600G and a Ryzen 5800X.
I could not zero in what's happening without having your PC in my hands.
Possible problems could be:
- You have a faulty 5800X.
- The processor is not installed in the socket correctly or you have some bent pins.
- Check all other internal connections to verify all is well.
Did you remove the 6600XT when doing the CPU upgrade? Check all connections to everything.
Have you tried the 5600G again to see if the PC will POST?
You might need to upgrade the CPU cooler, if you get the 5800X to work, as you are going from a 65 watt TDP CPU to a 105 watt TDP CPU.
