Hey everyone, I'm having a frustrating issue with my PC that suddenly shows no display. I've already tried a bunch of troubleshooting steps, including changing the display cable, reseating and cleaning the RAM, cleaning the air cooler, and checking the GPU and its slot. I even removed the CMOS battery for about 30 seconds. My power supply unit is also fairly new since I replaced it a few months ago after the old one failed. I tested my monitor with my laptop, and it works fine, so I don't think the monitor is the issue.
When I power on the PC, the fans spin, and my keyboard lights up, but the Caps Lock indicator doesn't light up when I press it. Here are my specs:
- ASRock B550M-HDV
- AMD Ryzen 5 5600X
- PNY 16GB (2×8GB) DDR4 3200MHz
- NVIDIA GeForce GTX 1660 Super
Does anyone have any ideas on what's causing this? Appreciate any help! 😢

Did you switch all the cables when you replaced the PSU? Sometimes a loose connection can be the culprit. Also, if you can, testing the GPU in a different setup would give you a definite answer.
Have you tried testing your GPU in another system? If you have a spare GPU lying around, that could help diagnose the issue too! It’s a bit of a long shot, but worth a try if you can.

Yeah, I switched all the cables. Everything was working fine until today, but I can’t test my GPU on another system right now.
