I got a GTX 1080 TI today and installed it in my computer to replace the 970s I was using. I turned on the computer and it gave a message that I forgot to plug in the power to the card. Doh. Well I turn off the computer, plug the connectors into the card and...

Now pushing the power button on either the case or the motherboard does absolutely nothing. IT doesn't even attempt to start up and there are no lights/sounds. I tried putting the old cards back in, just one card, only one RAM stick, etc. Same results.

Ideas?

Heya, thanks for the response. Front panel connections are still connected, and the power button directly on the mobo doesn't work either.

1000W EVGA PSU
GTX 970 x2 SLI
Samsung 840 EVO 1TB SSD
G.SKILL TridentX 4x8gb RAM
MSI X79A-GD45 Plus Motherboard
i7-4930K CPU

The issue occurred when replacing the 970 SLI with a single 1080 TI and persisted through every permutation thereafter.

Update:

I tested the PSU using the paper clip test and a multimeter. I then installed the RAM and one of the old graphics cards onto her computer one by one. Everything worked. I couldn't install the GTX 1080 TI because it literally won't fit in her case.

So with that in mind I have a few questions:

1) What are the chances that it is a motherboard failure compared to a CPU failure? The motherboard has no lights on at any point so I'm somewhat sure that it at least is dead.

2) What is the potential that the CPU is now also gone?

3) Is it possible that the 1080 TI caused the issue and could potentially cause the issue on a new mobo?

Thanks in advance for any input!
