Dead 780ti Jetstream? Any help appreciated.

[GregPalos]

Hi guys I need some help. My Palit jet stream gtx 780ti was running a benchmark and I touched the back of the pcb and the card just switched off. I'm worried I might have fried it. I've tried flashing it but the only thing that comes up is a plx 8747h. When I plug in my second gtx 780ti, the second one comes up in the bios and I can flash it. Any ideas?

This really sucks.

Try a different PCI slot first. TBH it does sound like something broke.

 

[GregPalos]

I've tried that

you touched the pcb while it was switched on???? that was a silly thing to do, think you have probably fried it fella

 

[GregPalos]

Just seems a bit ridiculous that doing that could fry the card. :l

depends on what you touched tbh, if you touched the pins behind the gpu core, its 99% fried, if you touched one of the memory chips, you MIGHT have just moved the card enough for the pci slot not to align properly anymore, try taking it out and let it dry for a couple of days, maybe use a hair dryer, could be some of the sweat off your fingers is shorting something not critical, and thats being VERY optimistic here.

That's where I tapped it:

I might use the hairdryer idea.

well its not the power pins, but i think thats the VRM's

jesus, how hard did you touch it?

 

[GregPalos]

jesus, how hard did you touch it?

literally dabbed it. like you would a babys hand.

 

[maniac]

youre finger might have acted as a conductor and shorted it out, I hardly think the hairdryer idea would work as theyre wayyyyy too far apart to be affected by something that thin.

Those are the solder points for mosfets & chokes, as the rest of the boys have stated it looks like you've shorted it. NOT GOOD. You could RMA it I suppose..

Why did you dab it anyway?

 

[GregPalos]

because it was colder than the other card but hotter on the back of the pcb. And I checked it like that :/

I guess its kinda like when you touch the car door and you get a sting of electricity. You shouldn't have wore socks on your carpet.

There are less invasive methods of checking the temps and a lot cheaper in the long run. IR Laser Thermometer for example Ebay £10.
