3090 behavior and static shocks.

[Merfalerf_TTV]

Hey everyone, awhile ago I ordered a PC. When I received it, it was working brilliantly. However, not too long after that, I started to get shocked when moving around on the couch while I had my two earbuds in. The shock would sometimes temporarily cause my TV to sputter, (The PC is of course connected to the TV) so I know it was traveling through the entire system. For some foolish reason, I didn't really think much of it at the time. However, my GPU eventually died, and I realized that it was extremely foolish of me to just have let this problem continue. I RMA'd the card and I received a new one, but ever since then, the GPU does not perform at the level the old one did before (at least I assume) I damaged components via these mild static shocks. However, I do not receive shocks while playing any longer. Is it possible that I damaged other components, despite the fact that my computer is stable and functions well, which cause the GPU to lose some of its functionality? Is there a way to test this at all? I'm not super technical, hence why I ordered a PC from a company. Before the problems, I was playing in 4K, and the card would perform amazingly well, hitting around 65 degrees C, (While streaming as well) and now, I am only gaming at 1080p, and the card heats up to 75ish degrees C, with the fans hitting around 2k RPM, sounding like a jet engine. I wish I had more information, but I wasn't really paying a lot of attention, I was simply thrilled with how everything was performing, but the dream came crashing down. I've never gotten static shocks before while just playing on a PC, did I do something wrong? Was the computer defective? Any help or advice would be appreciated.

What are the specs of the system? Psu in detail.

 

This info is not much to go off of. Was the pc on carpet? Was it in a grounded socket and was a grounded cable used?

 

For all we know you did NOT get a 3090 back or anything here.

My PSU is an 850W Gold, I'm unsure of the model.

Mobo: Z590 GAMING EDGE WIFI

Processor: 3.70 gigahertz Intel Core i9-10900K

GPU: NVIDIA GeForce RTX 3090

RAM: 64 gigs of 3200 DDR3 (4x16)

 

Yes, my PC is on carpet, but it is indoor/outdoor carpet, and sitting on rubber stoppers a good inch above the carpet. As far as if it is in a grounded socket with a grounded cable, I am uncertain. I don't know how to tell, I've never had experience with such things. It's a regular socket in the wall of the studio I have, and the wiring was done by a qualified electrician, so I am only assuming it is grounded, but I do not know for certain.

 

I did receive a new 3090, which I installed and has been functioning as described above.

 

Thank you very much for your response! I'm sorry I don't exactly know all the details.

There are grounding test plugs you can buy to test for proper grounding in an outlet, where it will light up green for ground and red for a fault.

Improperly grounded outlets are a VERY bad thing.

This.

 

That and OP basically insulated their pc from the ground with the rubber stoppers so the only thing grounding it is the psu ground. If that is not working then big yikes.

I suppose the stoppers aren't rubber. They're apart of the case. I am just using the case I was sent. It is an NZXT H510 Elite case. It has little "feet". Thank you for pointing me in the direction of the testers. I will certainly check that.
