Asus P8 Z77-V LK Bios / GPU Help!

[Millgo47]

I know I've been on here a lot asking about this but here goes...

I went through every thing possible on the Tom's Checklist
Bought a new PSU and still the same problem.
Returned the 780 TI Card for a new one and still same problem.
Bought a new motherboard and still nothing.

When I hook up the HDMI cable to the 780 TI it says no signal when I turn the PC on..
I turned everything in Bios to PCIE and still doesn't work.
I updated BIOs to the latest version and still nothing...
It's getting plenty of power and with the new PSU, 780 TI and Motherboard it can't be either of those. Only thing I can think of is something in BIOs?
I even tried using other PCIE slots and they don't work either.

I only updated the BIOs on from this website, is there anything else that should be updated?

I honestly don't know what else to do.

Thank you

Hello

What are you using for a monitor? Have you checked the monitor that HDMI is selected as the input? Test with a different HDMI cable?

Hello

Are you sure the system is actually booting up?
