Last week I purchased some components and assembled the PC. When I turned it on, all the RGB lights came on but nothing appeared on the screen. My dad and I managed to get it working eventually, but then it started again yesterday. I've tried everything now and nothing seems to help—it still doesn't display anything. The parts I used are: PC parts, Prime X670-P motherboard with Wi-Fi, Kingstin Fury 6400MHz RAM, AMD Ryzen 9 7900X3D CPU, RTX 4070 GPU, and a Corsair 750W power supply.
Ensure all power supply cables are securely attached. Check if you can update the BIOS.
It has started before and I’ve been playing games without any issues, but then something unexpected occurred.
