GTX 780Ti | Expanded view in-game, now no video out. Help?

[illumind]

Hi All. I'm running Windows 10 with a EVGA GTX 780Ti. The below issue also occurs with no peripherals plugged in and in other machines as well. It's 100% the card as the PC works fine with a backup card.

Last night I changed an option to expand the view in Titanfall 2 from '70' to '90' and after about 10 minutes of playing like this I received a black screen of which couldn't be escaped without switching off PC. CTR-ALT-DEL etc had no effect.

After switching back on the screen had weird blue artifacts on it. After switching off and on again it was good for a second when displaying the BIOS flash screen, but then went black before I could enter BIOS. Since then it just boots to a black screen.

I get 1 beep from the MB speaker for a successfull POST, and the GeForce light comes up with regular fan spin amount.

I'm about to take it apart just for sake of it and redo the paste, however I know it won't fix it cause the paste is fresh already.

Any ideas anyone? Anything is much appreciated!

You could try a different output on the GPU? But most likely it's time has come.

Mmm. I did try the HDMI also, with no luck, however that was when it briefly worked the second time around. What annoys me is it was running perfectly at 70° C while gaming until I stupidly decided to flick the switch that they warn you about in-game. It should be more in red writing and more obvious that it could kill your GPU. I think the card has/had plenty of life left in it, the problem was me changing that setting.

Also, "it's time has come" isn't very technical. Does anyone actually understand the way GPU's work and what's going on in greater detail?

Thanks.

It's very likely a heat issue. If the card spiked over 80 for very long, you probably fried it. As the heat builds, the solder onboard starts to soften and things start to have compromised connections, which can cause shorts in the circuit and destroy microelectronics.
The best you could do to try to resurrect your card is to have the board re-flowed. This means they heat it up and get the solder points nice and solid again. However, if you caused enough damage, this does not fix bad transistors.
It's also going to cost you $$ which could be used to get a better card... a much better investment for your dollar.

Good Luck.

Okay, thanks man. I'll probably select that as the solution, however a caveat for anyone else is that I was actually monitoring the heat at exactly the time it happened and it was at around 70° at the time. Possibly 68°, very consistently too.

Another interesting point is that the issue actually occurred on one earlier occasion (after changing the in-game setting)and powered up fine afterward. So weird. It pains me to throw $250 AUD away.

Anyway, I'll mark something as a solution soon.

Thanks again.
