I upgraded my motherboard, CPU, and cooler, and everything seemed fine at first. However, after a few days of use I encountered an annoying issue: the VGA LED on the motherboard would turn on and the system would sometimes fail to boot. After removing the GPU and reinserting it, it would occasionally work again. The unusual part is that when the system boots, it's quite stable—stress tests and game benchmarks ran without problems. But if I leave it alone and come back the next day, it doesn't boot at all.

System details:
Mobo: Asus TUF GAMING B550M-PLUS
CPU: 5800x
Cooler: thermaltake peerless assassin 120
GPU: RX 5700x
PSU: Bitfenix Formula Gold 450W
4 sticks of Gskill 3600Mhz DDR4

Any suggestions on what might be causing this problem? The GPU is large and long, so it's possible it isn't connecting properly to the motherboard. It worked fine for years in a MSI B450M Pro-VDH I owned before. Also, don't think the GPU is broken—it functions correctly when the system boots. Could it be that the PSU isn't providing enough power for all components? I previously used a 2400G with lower TDP. I've tried removing everything from the case and booting in that way, but it seems to make things worse.

Thanks, but sadly everyone’s power supplies are 450W or lower.
It’s worth mentioning my RAM is 3600MHz and I’m using it at the XMP profile with that speed and 1.35V (with four sticks). Could this be causing the instability and making it look like VGA issues?
My old motherboard couldn’t handle four sticks at that speed, but I was hoping a quality Asus board would fix that.

Could the VGA issues sometimes stem from an underpowered PSU? I didn’t experience this before, assuming there was enough power, but could it still be the reason? Also, might the motherboard or BIOS settings be the cause?

When it starts up, have you ever performed a stress test? Tests like the PSU/Power check in OCCT will make your GPU and CPU use maximum power, helping see if your PSU can handle it.
With that in mind, 450W leaves little room for the GPU/CPU combination. You're pushing it.
If you upgrade, aim for a well-reviewed model with at least 650W. You don't have to go overboard, but you should have more than what you currently have.

Thanks for the advice, I hadn't considered the software. The power consumption test showed normal readings around 300W. It seems the issue might not be with the PSU or the motherboard.
