I am building my new PC and I am getting no display or startup sound/BIOS but everything is powering up motherboard included. I have everything in the correct slots, at least I think so I have tried and been working for hours making sure.
SPECS:
Motherboard - Asus 990FX Crosshair V Formula-Z
GPU - Gigabyte/Nvidia GeForce GTX 780 3GB 1071mhz
CPU - AMD FX-8350 8 Core 4ghz
RAM - 4GB x2 G Skill Ripjaw DDR3 1600mhz (tried all 4 slots)
PSU - Corsair CX750W
I have triple checked that everything is compatible, the error on the motherboard says "FF" and the RAM LED light seems to stay lit up. Please help me, thanks in advance.
