Basically, my brother-in-law's MSI GTX 980 Ti Gaming 6GB prevents his PC from booting. So, I took it in and am trying to diagnose it.
What I found out so far in my test PC:
- Connecting no external power (relying only on the PCIe slot), the PC boots and the graphics card fans spin; logo light also turns on.
- Connecting only the innermost 8-pin power connector allows the PC to boot and the graphics card fans spin; logo light also turns on.
- Connecting the outermost 8-pin power connector, whether by itself, or with the other 8-pin, prevents the PC from booting. Furthermore, it flips the internal fuse on my PSU, forcing me to reset it by toggling the switch.
So, I want to see if I can fix it, but without wiring schematics, that's like finding a needle in a haystack. My next best option is hoping someone else knows what component causes this via experience or if a company rep sees this post and can give me a likely cause.
I know the card is out of warranty, and money is tight, so unless it's cheap (less than $50 including shipping), sending it in for repair isn't an option. I also understand any advice I choose to take is on me, not the advice giver. So I'd appreciate any clue and accompanying values that I can test and verify.
I know this is a long shot, as it's a very specific unknown (and there's only so much one can do over the internet), but I'm trying all avenues just in case.
