Recently I made purchase of a new Motherboard- http://www.newegg.com/Product/Product.aspx?Item=N82E168...
and a new Power supply- http://www.newegg.com/Product/Product.aspx?Item=N82E168....
After installation I quickly realized that my computer wouldn't post. I back peddled and started removing hardware as I know this could be a common problem with new hardware and compatibility. low and behold after removing my Graphics Card (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) The system booted just fine.
Could this be a problem with a faulty power supply? Or could this be any number of things.


Specs include : I-7 Sandy Bridge 2600k Quad Core
1 Corsair Vengeance 8gb Memory

You may want to check to see if theres a uefi/efi compatible firmware available for your GPU.

I saw this when looking over BIOS versions for this motherboard.
I don't know if this does anything for you, but you could try updating to the newest version if you haven't.
But in this version they added compatibility to some PCIE device...

Version 1103

Description P8Z77-V LK BIOS 1103
1. Enhance compatibility with some PCIE device.
2.Revise help string in BIOS.
3.Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/cpusupport.aspx?SLan...

I still have the CD that came with the Graphics Card when I purchased it, should I try and install that? Would that help any?

Well, you can remove your card, boot off of iGPU, set it as default, shutdown, put the 760 in, boot plugged into the mobo, and install drivers. Then, go into BIOS and set the new card to default again and tell me how that goes.

I tried that but as soon as I put the 760 in, The computer led lights light for a bout a second, then didn't kick over.

That is weird. Your new mobo seems like it is faulty in that slot. Try it in another slot. Try another GPU in those, too.

Tried my Geforce gtx 550 ti in that same slot. Loaded up fine and is working.
The only thing that really makes sense at this point would be the power supply, correct?

Honestly, barely any of this makes sense. Is that a new GPU?

That GPU could have died, and it probably did, given your symptoms. I would return it if it is in warranty and get a new one.

Should I also consider purchasing a new power supply or do you think that if given my GPU was sufficient it would be enough wattage to support it?

I would get a new one to be safe. With that setup, a http://www.newegg.com/Product/Product.aspx?Item=N82E168... would be sufficient and good.

okay, should I attempt to put my GPU in a friends computer just to make sure it's dead?

Yes. If it works, you have succeeded in stumping me.

Alright, good luck. I would get an ASUS R9 280 if not. It is better than the NVidia card, looks the same.

Costs about the same, too. A little cheaper ($20).
