Hey everyone! I'm new to PC building and I've just assembled my first rig, but I'm facing an issue: when I power it on, the fans start running, but there's no display on the monitor. I've included my build specs and the troubleshooting steps I've already taken. Any suggestions would be greatly appreciated! Here are my specs:
- **CPU:** AMD Ryzen 5 5500 6-Core
- **Motherboard:** B450M-HDV R4.0 (supports Ryzen 2000 - 5000 processors)
- **GPU:** ASUS Dual NVIDIA GeForce RTX 3050 6GB
- **SSD:** TEAMGROUP MP44L 500GB NVMe
- **RAM:** OLOy DDR4 16GB (2x8GB)
- **PSU:** MSI MAG A650BN 650W
**What I've tried:**
- Checked CPU pins
- Used one stick of RAM at a time, testing all slots
- Cleared CMOS
- Confirmed the monitor works
- Disconnected all case fans, SSD, and front panel wires
- Reconnected both motherboard and CPU PSU wires
- Verified the motherboard is compatible with Ryzen 5000.
Thanks in advance for your help!

A few things to consider: how long do you wait after powering up before getting concerned? The initial boot can sometimes take a bit, like 15-20 minutes. Also, do you have any beeping sounds? That can indicate if there's a BIOS issue. It sounds like you might need a BIOS update for the motherboard to fully support the Ryzen 5000 series GPUs. Check your motherboard manual—it might be a bit older and require some updates to work properly with the new CPU.
It's crucial to ensure your RAM is seated properly. Sometimes they might seem clicked in, but you have to push pretty hard. Double-check to make sure it's all the way in. Also, since you mentioned the motherboard is supposed to support the Ryzen 5000, it could really come down to the BIOS needing an update, especially since you don't have a speaker to hear any error codes.
I thought I heard the click when I installed the RAM, but I’ll definitely check again just to be sure!
You should definitely get a BIOS speaker. It could save a lot of headaches. I've been in a similar situation and having a speaker that alerts you to errors makes the troubleshooting process much easier. Either way, if you have to do a BIOS update, make sure you check the compatibility list on the manufacturer's website.
I agree! I never used to think I needed one, but it spared me a lot of trouble when my system wouldn’t post.

I waited around 20 minutes on my first boot, but since then I've been trying things and each time I only wait a few minutes. I'm also worried about the BIOS situation since I'm not sure if it needed an update.
