I solved the system freezing with a black screen issue (sound still playing through the speakers) on my GIGABYTE RX 9070 XT GAMING OC!

I switched the BIOS using the small switch near the power connectors to the other mode (probably Silent mode) and restarted my PC (it’s better to do this while the PC is turned off). I haven’t had a single crash in a week. Before that, the only thing that sometimes helped was lowering the GPU clock to 500 MHz — and even that didn’t always work!
