I'm having trouble with my PC—it won't turn on! I have a Ryzen 7 5700G paired with an ASUS Prime A520 MK motherboard, and I'm using 16GB of RAM with no dedicated graphics card. Everything was fine until I tried to install a 1650 4GB graphics card. Now, I just get fan spinning, but no display. I even removed the new graphics card to see if that helped, but I'm still having issues. The graphics card works because I tested it in another PC, and my power supply is a 550W 80+ Bronze. Any ideas on what might be going wrong?

I unplugged and re-plugged all the cables and even tried testing my RAM sticks one at a time. My motherboard doesn’t have diagnostic LEDs, though, which isn’t helping.
Have you made sure all the cables are securely connected? It's possible something got loosened during the card installation. If your motherboard has debug LEDs, check to see if it's stuck on any of them, like CPU or RAM.
What's the brand of your power supply? Knowing that can sometimes help in troubleshooting issues. Also, I’m curious—does it really matter? I've had great luck with 80+ Bronze supplies lasting longer than some Gold or Platinum ones.
