I've finished assembling a new PC, but when I try to boot into the BIOS, the system powers on without showing anything on the monitor. All the fans and components appear to receive power. The parts are an AMD Ryzen 5 8400F, ASRock A620AI motherboard, Corsair Vengeance RGB DDR5 16GB kit (CMH16GX5M2B5200C40), ASUS Dual GeForce RTX 5050 8GB GDDR6 OC Edition, and a Lian Li SP750 V2 750W SFX power supply. The monitor is connected to the graphics card. What should I check to find the cause of the missing display?

Post clear photos of the completed build, especially the motherboard power connections, graphics-card power cable, RAM installation, and the case’s front-panel wiring. Those areas are useful for spotting a loose connection or incorrectly seated component when the system powers on but gives no signal.
Make sure the monitor cable is connected directly to the RTX 5050 rather than one of the motherboard’s video ports. The Ryzen 5 8400F does not include integrated graphics, so the motherboard outputs will not produce an image.
The monitor is connected to the graphics card, so that part should be correct.
