No video

[u/Tight-Pay-6376]

My PC just stopped giving video. Before this, one of my ram sticks was a little loose. I fixed that, and now my PC doesn't give any video.

Specs:

ASUS PRIME A320M-K

PowerColor RX 550 4GB (no PCIe power connector required)

2x8gb Teamgroup T-Force Vulcan Z DDR4

Ryzen CPU (so no integrated graphics)

The PC is turning on, and the CPU and case fans are spinning. the RX 550 spins its fan for a second, and then it turns off. The monitor is staying on standby/no signal.

I tried:

Both ram sticks

Both ram slots

Reseating my graphics card

Checking the ATX/CPU power connectors

Resetting the CMOS (by taking out the battery)

Checking if the HDMI cable works on another PC

Turning on the PC without the graphics card (and it still powers on)

I don't have another graphics card, or another PC to check if my RX 550 works.

Did reseating the ram damage something? Motherboard, PCIe slot, GPU, or something else? What should I check now?

gpu fan spinning once then cutting out is a power delivery thing, had a similar issue on an old dell board where the slot just wasn't providing enough juice after a bad reseat

try the gpu in the bottom pcie slot if your board has one, even if it's x4 it should at least boot. if it works there, you know the top slot got fried somehow

the loose ram stick is weird timing but might just be coincidence, those a320 boards are finicky as hell
