I'm having trouble after swapping out my MSI 1050 Ti for a new Intel Arc B580. When I try to boot, I see the BIOS option for only a couple of seconds—much shorter than usual—before my keyboard, mouse, and monitors turn off, even though the PC is still running. Then the BIOS screen comes back up.
I have a Prime B550M-A motherboard paired with a Ryzen 7 5800X. I've uninstalled the drivers for my old GPU using DDU and haven't installed the new ones yet. I also updated the BIOS. To troubleshoot, I put my old GPU back in, and it works fine.
One thing I've noticed is that while the new GPU's fans run for a few seconds and then turn off, the LEDs stay on. I feel like the GPU might not be seated properly in the motherboard slot, but I'm not entirely sure. If anyone thinks a picture might help, I can share it. I'm relatively new to building PCs and have tried basic troubleshooting steps found online, but I'm running out of options that don't involve spending more money or investing a lot of time. Any advice would be appreciated!

Have you double-checked that your GPU is properly powered? It might sound basic, but it's easy to overlook. Also, make sure your power supply is adequate; while 600W should generally suffice, you might want to confirm that it can handle your system's full load, especially with the new GPU.

Thanks for the tip! I do know to plug in the power, and my PSU is 600W. I've heard 500W should be enough, but is it possible I need more for this setup?
