why do gpus randomly need reseating?

Threepwood · 29 Aug 2024 at 15:55

as long as I have had modern pcs, there have always been seemingly random times that the gpu needed reseating to fix a boot display problem, but why,?
It's not like they are taken out to allow some dust to get in the slot? they are pretty much left there alone, static, working, then boom- reseat me plz!
so, I just don't understand!
yes, I crapped myself a little with a gpu debug white light on yesterday, cba with a broken 4090, I had to wait until my son got back from his twilight shift job to reseat it for me, it took x3 reseats before the white light went off , and I got the sweet green light again
any idea anyone?
EDIT:just to be clear, i'm talking about fixing a sudden no video signal error, or a vga problem debug led

I have never reseated a GPU ever (Assuming it was initially inserted and working correctly)

If anything its more likely to be a power cable or display cable issue that 'reseating' the GPU is resolving (But isnt actually the root cause)

I've never needed to reseat a GPU

I've never had to either. Are you moving your PC around or is it getting kicked?

Same, never needed to reseat a GPU.

Your card or some other component is likely on its way out. You don’t need to reseat a gpu unless it’s taken a bump or wasn’t seated properly the first time.

Never had to reseat any of mine, I've had to a few times at work when people have bought cheap cases and the chassis has bent when they've incorrectly installed the GPU.

funny how it is the first piece of advice given whenever somone is having a vga / gpu signal problem, or if a vga debug led is on

Never done it either. I dont think ive ever needed to.

The only time I've ever seen a VGA debug light on was when I tried a much newer GPU on an older motherboard. Needed a BIOS update to resolve.

I'd assume it might be more common with very large/heavy cards, but I've not had to randomly do it.

I've seen all manner of sized cards do it. totally randomly

All in systems you've owned by any chance? Because like others have said it's never happened to me or something I've ever heard of. I've heard more about GPUs ripping out the PCIe socket in transit than I've heard of it falling out...

my PCs and my kids PCs
I'm not talking about reseating a gpu because it has fallen out of the socket! but to fix it when suddenly there is no video signal coming from the pc
I refuse to believe that I am the only one to know that reseating the gpu, can fix a no signal error

john_smith · 29 Aug 2024 at 19:11

Never happens.

Reseating ram though, I’ve had that countless times on older systems.

You don’t think it’s this guy messing with you?

How does a gpu being "unseated" cause a no signal error on the display?
Normally no signal errors are just crap cables

I have not once said anything about a gpu being unseated, but I can see your confusion, reseated means taken out, and plugged back in!

So why would it need reseating / why would reseating cure it?
