I recently completed building an AM4 computer, but when I try to boot to the BIOS, nothing happens. The motherboard shows some power since the orange backlight LEDs are lit, but none of the case fans or cooler fans are working, and overall there's no sign of life. I've checked all the connectors to make sure they're seated properly. For context, the GPU is not in the slot to access the connectors, but that hasn't changed anything. Here's the list of parts I used (everything is brand new except for the graphics card): CPU - Ryzen 5 5600, Motherboard - ASUS Prime B550M-A WiFi II, GPU - MSI GeForce RTX 3060 Gaming X 12GB GDDR6, RAM - G.Skill Ripjaws V DDR4 16GB, PSU - MSI A750GL PCIE5, Cooler - Deepcool AK400, SSD - Kingston NV3 1TB, Case Fans - Thermalright TL-C12C 120mm, Case - Thermaltake Versa H18. Any tips for diagnosing this problem?

Were all your parts new? Sometimes used or old components can cause compatibility issues.
Here are a few things you can check out:
1. Make sure all cables are properly connected, especially the CPU power cable.
2. Check the power supply itself to ensure it's working.
3. Avoid daisy chaining too many fans together as that might create issues.
4. Verify that all fan connections are secure.
5. If you have a compatible CPU, try swapping it to see if your CPU might be dead.
6. If you have an older motherboard that supports DDR4, try testing your new parts on that; if it powers on, then the motherboard or CPU might be the issue.
7. Test with single-channel RAM.
8. Use dual-channel slots (1 and 3 or 2 and 4) to rule out bus issues.
9. Resetting the CMOS could help, though it's on the unlikely side.
10. Make sure to check with another monitor just to rule that out.
11. Lastly, you could try using the integrated graphics, if available.
Let me know how that goes!
Good luck! I hope one of these steps solves the issue.
