Hi

So I upgraded my GPU to the RX 6600, my PSU to a 500 W one, and my RAM to a dual channel 16 GB. I installed everything. My PC did start, but the screen doesnt get a signal. I put the HDMI cable into the graphics card as supposed, and it also gets powered by a 8-pin PCIe cable. So what is the problem?

Greetings @_What_Ever 

 

Welcome back to the Forum.

 

I can think of two possible issues using the RX 6600 if the card is correctly installed in the MB and the monitor is: working and set to the correct HDMI input to receive video from the RX 6600:

 

- You may need to disable Secure Boot and enable Legacy support. Check this HP Site for details. Look at "Secure Boot settings for Desktop computers".

 

- The pre-owned RX 6600 may not be in good working condition. I'm guessing the RX 6600 is not brand new.

 

Can you possibly try the RX 6600 in a different PC to see if it works?

 

Regards
