I'm having some trouble with my Mini-ITX PC build. After replacing the thermal compound on my GPU and reinstalling it, I'm not getting any signal to my monitor. I've tried various troubleshooting steps, including removing all components from the case and testing the RAM, PSU, and GPU on another setup where they worked fine. I've also attempted to reset the BIOS, but the fans and AIO cooler light up without any video output. Here are my specs for reference:
**Motherboard**: ASUS ROG Strix Z690-I Gaming WIFI
**CPU**: Intel i5 12600K
**RAM**: Kingston 16GB x2 DDR5 4800MHz
**GPU**: Nvidia RTX 3060 Ti 8GB
**M2**: Samsung 970 EVO Plus 500GB
**PSU**: Phanteks Revolt SFX 750W 80+ Platinum
**Case**: Lian Li Q58 PCIe 4.0.
Can anyone help me figure out what might be going on?

First off, check that the GPU riser cable is properly connected. Since your GPU is mounted sideways, a bad connection there can definitely cause signal issues. Also, try booting the PC without the GPU and use the onboard iGPU—if that works, it could indicate a problem with the GPU or its connection. You might also want to double-check your RAM. Sometimes reseating it in different slots does the trick. And if you have a motherboard buzzer, that can be super helpful in diagnosing issues!
Thanks for the tips! I did swap the GPU out for the iGPU, but I still got no signal. I also reseated the RAM multiple times in different configurations, without success. I’ve never used a buzzer before, but I’ll definitely look into getting one!
