[ASRock Z77 Extreme 4] New system build, no display, three long beeps

[Gran Torino]

Greetings,

I have just rebuilded my system, everything is connected properly, all fans are spinning and all lights are working but when I try to boot I get no display and three long beeps from mobo speaker. I used mobo manual and google to find out that it is the RAM issue. I have tried all memory slots in every possible combinatios - but no changes. I have tried another memory but situation remains the same. Any ideas or suggestions?

My memory is: Corsair Vengeance 2X4 GB 1600 MHz red (I have also tried Kingmax 2X4 GB 1333 MHz)

Other specs:
CPU: Intel i5 3570k
PSU: Corsair TX 850
GPU: Gigabyte HD 7970 OC

Thank you in advance.

if it runs on default error codes its a keyboard problem (usual). Some bios however its RAM related ... and again might be different. Don't know your board or bios, but maybe it gives a hint in the direction.
