Installed 3080 Ti and now nothing is working, please help!

[BobFish]

Hey everyone, I was doing a simple GPU upgrade on my friends pc yesterday but something seems to have gone wrong. All I was doing was replacing his 2070 with a 3080 Ti (I built the original PC) but for some reason its not working. When we put the new GPU in the motherboard speaker does one long beep and then 3 short. We have determined this is to do with a GPU problem from looking online.

 

I disabled CSM in the bios as this seems to be a common issue with the 30 series GPUs but this unfortunately didn't help, the boot drive in this pc is a sata SSD so I assumed this wouldn't have any issues there as it seems it only affects boot PCIE drives.. I also reseated the ram because a few sites suggested that (but I didn't really expect this to do anything).

 

I also switched from using just one power supply cable to two separate ones as that was suggested.

 

Unfortunately now after removing the GPU it still gives the same error even when no GPU is connected (trying to just use integrated graphics on the i7 8700) and no image is displayed.

 

I no longer have the old 2070 as that was sold to someone else. I could potentially try putting the 3080 Ti in my build but I'm a little concerned the card is DOA and somehow screwed up his system (doubt this but I suppose it could be possible).

 

Any ideas?

 

His build:

CPU: i7 8700

GPU: Galax 3080 Ti

Ram: 2x 8GB ddr4

Motherboard: Asus TUF H370 Pro Gaming Wi-Fi

Power supply: Its a fully modular 750w I think by thermaltake? Its a pretty good model, definitely 80 plus something (I think gold but not 100%).

Try reset your BIOS.

maybe you broke the PCIe slot by mistake, hopefully not tho.
Hope the gpu works, really hope it does.

Good point, will do that and post if that works

Man I really hope not as well. Definitely didn't force it or do anything that I think could have broken it. This is a very heavy card though so need to be careful. Also very expensive so definitely don't want to do anything that could damage it.

There's been a lot of talk here against Double Forward PSUs with 30** gpus, you might have a Double Forward

 

You use HDMI or DP ? do you have a 2.1 HDMI cable (this shouldn't be your problem though) ?

HDMI is better when dealing with problems

 

The CSM thing sounds odd for a gpu problem

what does a double forward PSU mean and how does it affect the gpu? Not heard of this so very curious

I don't know much more than you only that it's an issue. But you should be able to find information with that in mind
