New Asus P8 Z77-V LX won't boot
Asus p8z77-v lx motherboard

Intel core i5 3350k CPU

To be honest, this is my first time building - all pieces are brand new, recently bought from Amazon. I followed all the instructions on the MOBO manual, turned it on, but then, although I get all the case fans running, nothing appears on the monitor and the DRAM LED light comes on (first it blinks twice then steady on). There is no beep, which I believe is because I don't have a speaker for the motherboard.
I have tried reseating the memory sticks and changing channels at the same time I tried MemOK. The latter did 2 different things: with some combinations, it would do the test (blinking DRAM LED followed by restart - some 3 times or so), then turn the pc on again with a steady DRAM light on. The second thing I experienced was the same testing process but with the PC being turned off at the end of the test.
I have also checked the CPU for bent pins, but it looked normal. Also tried running it with the minimum stuff plugged in (only PSU, no drives, no graphic card), but it didn't work either.
Should I replace any component?
