Hello Tom’s hardware community,
This is my first time posting so I apologize if this thread is in the wrong location.

just recently my pc has been having issues and I really don’t want the issue to be the graphics card but it very well may be. I’ll start with the

specs:
Amd ryzen 5 5600x
Gigabyte vision RTX 3070ti
Corsair rm 750 80W gold psu
Oloy Warhawk 4x8gb ddr4 3600
asus rog b550-A mobo
1tb Samsung 980 pro ssd boot drive
2tb seagate hdd
Windows 10

I built this pc around March 2021 all parts brand new.

Last week, I drove my pc from San Diego all the way to the Bay Area. Didn’t take the GPU out the slot. Wasn’t a super bumpy ride but it was 8 hours (700+ miles). A couple of days ago, my power strip short out because I had my pc, monitor, and a small Costco heater hooked up to it. This happened 2 times as I grabbed another power strip and used all devices again. The startup was fine and everything was going well when I unplugged the Costco heater.


Today, I’m starting up my computer and everything starts up, but the video crashes after a couple minutes and disconnects from my monitor. The rest of my peripherals stay on. Mouse keyboard, the computer fans stay running.

I’ll attach a video to hopefully help describe my situation more. The photo I took is also right after the video. I didn’t restart the computer.

Always remove or support the GPU when transporting PC.

Try to re-seat the GPU in its slot.
I gotta learn it the hard way I guess haha.

I’ve just tried reseating the gpu and disconnecting and reconnecting the pcie power cables. Sometimes I get lucky and the monitor turns on for 5 minutes. But as of now it’s not even connecting to my monitor.

the VGA light on my motherboard is on as well as the fans on my gpu.

Hey drivinfast,

I actually bought another asus motherboad x570 prime and it actually has the same problem for some reason. Pcie slot 1 doesn’t work or loses connection very fast, but when I put it into slot 2 it runs perfectly.

turns out when I have the gpu in either slot, the pc disconnects from monitor when I bump or shake the pc.

I’m going to try to swap the power supply to see if the power cables are the issue. Any other ideas?

Update: my problem has become the exact same as this user’s. The only difference is sometimes my pc will start up and my display does have a signal until I bump into it again.

I have also replaced and reseated literally everything in my computer (even replaced mobo) except my computer case, and the graphics card.
