Hi!

Just made an account. Anyways, as I’ve said in the title, my gpu’s probably dead. Got my card last july 2013 (barely one year old)

Some context:

I just came back from a 2 week vacation abroad. It was summer time here in the Philippines, meaning the temps. reached 37ºC/ 98ºF and relative humidity reaching 100%. When I booted up my pc, no display was showing, and since I didn’t need the gpu power yet (I used it for school work, GPU rendering), I switched to the internal graphics card and decided to fix it some other time.

Fast forward to today, I’ve already been trying to fix the problem for almost two days. Fans still work but the gpu isn't being detected by the pc. I’ve reset the CMOS, bought a new battery, updated my BIOS, uninstalled the drivers, reseated the card to the second PCI-e slot, plugged in to DVI, cleaned the contacts, nothing was improving. Next, I went online to check on EVGA’s warranty policy, and it said to resolve the issue first with the reseller. Since I had no other choice, I went back to the shop that sold me the card (I also brought along my setup to check if anything was wrong, hopefully not the GPU). There, I tested my mobo with another gpu, and it worked. The guy checked my 780, and told me that the card had some corroded capacitors and a chip. I checked it out online and found out it was called white rust / wet storage stain. Anyone heard about it before?

Anyways, I’m all out options right now. The guy at the shop said they could try to repair it but it was no guarantee, and he also said that if they send it back to the local distributor, it’ll just get void and sent back, since under the policy, corrosion is under physical damage caused by the user.

Here are some pics:
Here's a chip with some white rust on the right side.

Here's what it looks like without corrosion.

Here are the corroded parts (near the gddr5 modules of the gpu)

Specs:
CPU: Intel i7 3770 3.4GHz
GPU: EVGA GTX 780 ACX SC
Mobo: Gigabyte Z77-d3H
PSU: Cougar GX 1050W
SSD: Plextor 128GB
RAM: Kingston Hyper Blu 16GB

I just filed a Guest RMA with EVGA, hoping that they might find a solution for this too. Hopefully, I'll get some good news.


Probably, since I've heard of other similar cases near my area. Sadly, this is my first build, so I don't have any access to other gpu's.



Do you know any probable reason as to why those parts may have corroded? I really doubt that humidity was a factor (although, poor case ventilation and high humidity may have something to do with this). And would this be enough to kill the card?
