RX 7900 GRE

Random black screen, I will be doing anything on the computer and suddenly it says signal lost and goes to a black screen. This a new build, I am running a Aorus B650 elite ax v2 main board with 32 gig of ddr5/4800 ram, AMD 7-7800X3D CPU and the Asrock Steel Legends RX 7900 GRE. When it runs it is very good but it's hit or miss. I have done a brand new Windows 10 installation, With all new Adrenalin drivers, I have liquid cooling on the CPU and the GPU never gets above 42 temp. I have upgraded the mainboard BIOS to the latest version and set everything to default/ auto. I am beguiled and perplexed, this is the first time I have gone with AMD, I have never had any problem like this with Intel so I am a AMD lost NOoob. Any sugestions will be tried, Thank you.
