Device fails to communicate with the display.
Hello there, I just set up my first gaming PC and everything worked fine until I connected it to my monitor. The fans were spinning but no video signal appeared. I tried various solutions from forums and the steps I took: changed GPU, checked connections, reset CMOS battery, swapped RAM slots, inspected CPU pins, ensured the motherboard wasn’t touching the case, and more. All basic checks passed except for the video output. My final thought is that one component failed. Since I don’t have another PC to test the GPU on (most friends use laptops), my first guess is the motherboard or GPU itself is dead.
Regarding your AORUS PRO WIFI B450: it didn’t produce any beep when powered on, nor did it show any error codes. That’s unusual—usually a beep indicates a problem. It might mean the GPU isn’t working properly or there’s an issue with the power delivery. I’d recommend checking the power connection, testing the GPU with another monitor, and ensuring the motherboard supports the B450 chipset. If it still doesn’t work, you may need to replace the GPU or motherboard.
Let me know what you find next!
