So, basically I have a dead MSI 1070 Ti Gaming without warranty. The person whom I bought it from had opened it. It just needed a bios flash, but while I was busy trying to bios flash it, I heard an electrical buzz and my pc went off. Now, when the gpu has the 8 and 6pin plugged into it, my pc doesn't switch on at all. I think blown caps, but cannot see any physical damage on the gpu. Any advice would be gladly appreciated :)

So does your PC come on if the 6+8 pin isn't connected? Are you sure your psu isn't the one causing problems.
Your best bet would be to try A: a different psu then B: a different motherboard.

PC comes on without the 6+8 pin connected. I tried with the 6+8 pin my gtx 980 ti runs with and still the same issue, so the PSU isn't a problem. I haven't tried a different pcie slot. Will try the current pcie slot my 980 ti runs on. Thx

Sound like a short-to-ground. Best would be to get a schematic or test a identical card with a multimeter. If you boot with no power to the GPU or just the 6 or 8 pin connected, what happens?
If I boot with no 6+8 pin the LED's of the GPU is lit, but no fans spinning and my pc boots fine. If 6+8pin is connected pc won't switch on at all. It's like there is no power cable plugged into my pc and I am trying to switch it on. How do I test short-to-ground on the gpu? I have a multimeter, but I am not at all too familiar of testing electronics. I know how the caps look like and thats about it...Thanks for the input :)

When you say it does't turn on you mean no fans and motherboard beep or no image?

Try with the GPU connected but the screen connected to onboard. I don't see why a broken GPU would prevent system boot.
