Hello, my pc was working fine until last night. I have a x79 classsified and i have installed nero 2015 originally. After restart, pc stop sending video, even from bios. I have tested video card in another pc and it is ok. I have cleared cmos, start with no ram, 1 stick, no hd and bios switch on 1,2,3. 2 and 3 give Post FF, 1 is stuck on post 04 and still no video. I have take out cmos battery and Nothing. I have 1 1/2 year with this pc. Not an issue until now. i have win 7 64 bits. I don't know what to do to get video working. Any help please.

Sorry about this issue with your motherboard. Try re-seating all your power connections on your motherboard as well as your CPU, test with a single stick of memory and with and without a video card to see if you continue getting the straight FF error with switch 3 and test with the other 2 switches. 
Last test would have to be barebones with the motherboard laying flat on a non-conductive surface after that if it still fails to POST with any video or with error codes you're looking at an RMA. Make sure to test the video card in the different slots on the board as well.

Can you re-check your Code of 19.

Hello,

I been trying a lot of things and no succes yet. I reinstall cpu and now im getting code 19, autorestart and then I get stuck at code 04. No video signal yet in any type of monitor. I need to know if it is the processor or the mobo. I have a i7 4930k Installed.

Thanks.
