Hi all -
I purchased an EVGA 3060 ti via eBay from a well-known UK retailer. The card was quoted as being returned with a prebuild system with a motherboard fault.
Received the card yesterday, it had minor damage to the case bracket (described in eBay listing) which I very carefully re-set so the card sits entirely flush against the screw holes in the case again. First issue sorted, but there had clearly been quite some force used for the bracket to be as bent as it was but nonetheless, a minor repair.
I installed the card with two 6+2 pin Corsair extended PCI cables. The card shared the same driver as my previous one (checked and double checked with Nvidia website). Initially the 3060 ti ran fine. Left for five minutes before testing a game. I tested Battlefield 5, within 2 minutes, hard crash and slight pixelating around the area where the mouse pointer was. Sound was frozen.
I restarted, the card seemed to be okay. I left it for around ten minutes.. the driver stopped responding and recovered, then hard crashed entirely.
I had two brand new Corsair PCIe Type 4 power cables, so I installed those to make sure it wasn't a power delivery issue. At this point I will say it's a 650w PSU, this card requires 600w, and the total power draw is 585w so there is headroom.
After installing the new power cables, I retested. Battlefield 5 was fine in the menu for 10 minutes but then within 5 minutes of playing a multilayer match a hard crash with artifacting.
On restart, small green lines dotted around the screen. I turned the pc off and calmed down for a bit.
I restarted and got into Windows and despite one or two driver crashes, I managed to restart in safe mode, and performed DDU twice for good measure.
I reinstalled fresh driver, with 3060 ti installed. The driver installed fine, but then within 5 minutes on Windows desktop the pc hard crashed.
At this point, I took the 3060 ti out and installed a 1070 ti. Operation entirely normal. Tested 4 games. No crashes.
I then rage quit for the evening.
I continued testing this morning, no joy. The 3060 ti would instantly disable the inputs on driver initialisation, and I tested them all, and would remain black screen until the pc was turned off and cycle repeat.
I removed the graphics card again and performed another DDU. I tried reinstalling the graphics driver with the 3060 ti installed and as soon as the driver tried to initialise during installation, the above happens.
So, I removed the card, performed another DDU, but this time reinstalled the drivers with the 1070 ti installed. Driver installation fine. Game tests, fine. Turned off pc, installed 3060 ti, restarted.. black screens.
There is only one thing I can think to do now, to test further, and that is, after watching a video on YouTube, someone advised to start the pc up using onboard graphics. Once in Windows, disable the onboard graphics driver in Device Manager to try and force the GPU to co-operate. If I try this, I am worried that it still won't work.
Can anyone offer some advice?
Any help is appreciated. I am pretty experienced, but I have never had to fix a graphics card with this extent of problem before, so anyone with more knowledge would be really appreciated.
