I just built my first PC last night, and everything seems to work fine until I boot it up. I see the VGA and boot lights on my motherboard, but there's no display on the monitor. The light on my graphics card (ASRock Challenger) isn't turning on either. I've reseated the GPU and checked all the cable connections, but I still have no success. Since I'm new to this, I could really use some guidance on how to troubleshoot this issue. Thanks in advance!
Here are my components:
- CPU: AMD Ryzen 7 9800X3D
- MOBO: ASUS B650E-E TUF Gaming WiFi AM5
- RAM: Crucial Pro Overclocking 32GB DDR5-6000
- GPU: ASRock AMD Radeon RX 9070 XT Challenger
- PSU: Super Flower Combat GF Series
I also have some photos of the system, which you can check out here: https://imgur.com/a/X63d6L7 and here: https://imgur.com/a/ov9elKR.

Have you made sure the power cables are connected to your GPU? That's a common oversight. If you haven't confirmed that yet, definitely check those connections! Also, if you can, share a picture of your setup—it could help diagnose the issue faster.
It sounds like you've done some good troubleshooting already! Besides checking the power cabling on the GPU, see if the monitor is switched to the right input source. Sometimes, it's just a matter of the monitor not being on the correct setting. And don't hesitate to try reseating the RAM as well. It might just need a little adjustment.
