No video output from motherboard/gpu. Gigabyte Z77MX-D3H

[Brian Lewis]

No video output on iGPU or GPU on Desktop. Motherboard not posting. GPU fan spins at 100%. I've tried removing all RAM sticks and tried each one by itself. I've removed all hard drives. I've reset GPU and tried without GPU. I feel like I've tried everything at this point. It's a new power supply. I've tried two other power supplies as well.

I can't get Dual BIOS to kick in, either (no switch on this board so I have to use the power cycling trick).

Pulled the little battery from the motherboard and waited 60 seconds?

Got both the 24 pin and 4 pin power connectors in probably?

Got the ram in correctly?

Cpu still good?

No bad USB hub connected?

Edit: seems your board has the clr cmos pin switch which does the first question.

Yes on all questions.  I'm taking a guess here and assuming the motherboard is shot. The power supply failed due to being plugged directly into a wall and no surge protector. I'm guessing that it took the motherboard out with it.

Thats not good, you can either play will it work again with the cpu in another z77 board or go to z170 and newer cpu. I have a z77 board too and the newer cpus arent all that much quicker. What ever you do, get a surge power board or UPS

you need to check all the parts separately using another working computer.

First check CPU (& CPU Fan?) then RAM, Motherboard.

you will get the faulty part.

Yep, it was a rig I had sold to a family member.  The whole setup was quite nice, too, so I'm a bit bummed out about it.
