Question I have a brand new GTX 3090 that was just sent to me by nvidia but it doesn't seem to be working, the previous one that I sent back experienced the sa

A friend asked me to build him a crypto rig. I did. He paid for all the parts. He got a GTX 3090. I set it up quickly and easily (I've built 6 or 7 computers before but this was my first crypto rig). The 3090 worked fine for maybe a month. Then it just stopped. It wasn't recognized when I plugged it into the PCI-E GPU Riser and it wasn't recognized when I plugged it directly into the PCIe slot either. Won't power a monitor either. It worked on both previously.

I figured the card must have gotten fried or something, so I got an RMA and sent it back. I just got the new one, and it exhibits the same problems.

I know that the PCIe slot it working fine because I also have a RTX 3060 that works perfectly when I plug it in.

I was wondering if perhaps it's some kind of power issue, but as it worked before I know my power supply CAN run it, and also all the GPU rainbow lights come on when I turn on the computer (for whatever that's worth). Also, if I take out the 3090 and drop in the 3060 everything works fine and exactly as expected.

Any thoughts on what the problem might be?

Thanks!

I wouldn't write it off just yet - keep an eye on it.
