Function operated during testing but now the screen is missing.
Hello, your new PC build performed well during testing, but once installed, it fails to boot properly. The CPU fans and GPU lights are on, along with the case fans, yet the monitor doesn’t detect any input. I’ve confirmed the display cable is correctly connected to the GPU. You’re using an MSI Pro B-650 board, two RAM sticks, AMD 7 7700X, and an RTX 4060 Ti. The EZ Debug lights indicate all components are connected without issues except for the BOOT light, which stays on continuously until Windows installation is complete—something I can’t achieve without a working display. During bench testing, everything functioned correctly, and I managed to enter BIOS successfully. Now I’m unable to proceed.
I checked the troubleshooting actions taken. I did not introduce any additional fans or parts inside the enclosure beyond what was already on the test bench.
So far, I've only verified all the connections. I added the case fan links and the front panel connections. Now I'm planning to test an HDMI cable today.
