I think my GPU is damaged but I got no way to test it. Need help.

Awhile back(just over a month ago now) I had some water damage to my pc. My gpu stopped working for a while but after letting it dry for a few days everything seemed to be fine....or so I thought.

Today after gaming for 45 minutes I had pinkish looking boxes appear on my screen, a loud screech, and then the screen went blank for a few seconds before running again. Assumed it was the game and tried to carry on, happened again and I got nervous and turned off the game and just tried surfing the web in the mean time.

After 10 mins my screen froze and turned blank for the final time. I have not been able to get anything to show on my monitor since then. I think my system is fine cause I checked my mobo and after the usual post numbers it starts showing CPU temps since my mobo has temperature monitoring. Unfortunately I have no mobo speaker so I cant listen to the post beep. Exact same sequence of events happened the last time when I had the water damage so Im fairly confident that this problem is isolated to the GPU.

With all that said, I need to know if its safe for me to go ahead and put an order in for a new GPU. Is there anything else I can do to make sure nothing else is the issue. Some water did spill on the PSU as well so I wonder if that could also be the culprit and not supplying enough power to the GPU. If that where the case the GPU still should power up under no load, right?

Since that time I got the PC running again after the water damage till today I have not had any other issues with the PC; no BOSD, no PC hangs, not even any noticeable performance issues.



Looking for advice on what to do next.
Thank you for reading my very long post.

PC:
i5 2500k
GTX 570
Biostar mobo
Seasonic 620wtt PSU

Hard to say. I'd just leave it in that slot and hope for the best. Maybe the water corroded the contacts on the first slot. As to the resolution maybe you need to re-install drivers?
Can you run the PC with the on-board GPU to see if everything else is OK? Or have you already done that? It wasn't clear to me. If it all works well without the PGU, then yea, assume the GPU is the culprit.

It sure sounds like the GPU, the way it artifacted like that, but it would be nice to confirm it 100% before you order a new one.

How did you get water damage BTW?

My mobo is a p67 type so I cant use integrated CPU/GPUS. There isnt even a display port anywhere on the mobo.

Would it be possible to test my gpu on the second sli slot? Looks like the bandwidth is halved according to my mobo manual but I wonder if it would be possible to try running my gpu that way to test it at least.

I accidentally spilled a bottle of water on my PC desk. Sounds worse than it really was since I managed to get the pc out before more damage could be done. Only the GPU and the PSU had any signs of visible water damage so that why I feel like these 2 areas might be best to look at first before moving on.

Oh well this is bad.....Tried the second slot and it worked, tried to see if it would work in the first slot just in case and it didnt. Currently posting from the PC with the gpu in the second slot. Does this confirm a mobo problem? I would have rather it been a gpu problem and just bought a new one instead and be done with it. A mobo failure is gonna cause me more headaches....gahhhh!

So I should go ahead and get a new mobo then if I can run the gpu fine in the second slot or wait and see if the gpu acts up again?

Also I cant set my resolution to 1080p with the gpu in the second slot. Any ideas?

Gosh, all my upgrade plan for the year are now ruined. Maybe I will just get a new gpu anyway and see how long the mobo will hold out for and then replace it. At least I know where the defect is now.
