So i just got a new Asrock H87 Performance motherboard and an intel i5 4670.

Once i put everything together my and tried turning my pc on, no externals would work (mouse, keyboard, monitor etc.) and only the fans on the gpu and tower would work, it would also self restart itself ever 30 secs or so on an endless loop of turning on and off.

I tried taking it all apart and putting it back together but i only got the same results. I tried tightening the cpu fan, checked if there were any misplaced motherboard mounts, and took out the gpu, ram and hdd one at a time to see if anything would help. still nothing.

so could either one of them be faulty or could i have missed something?

Try to reset the cmos(bios). Try to rearrange the whole ram(according to clock and capacity). Remove the hdd's and gpu as well and boot it.. Give it a shot. :D

If the system powers up but you do not get a system post that Identifies the cpu you have placed in the socket of the board.
And seems like it is stuck in a loop, trying the post setup, it is because the current bios firmware may not be able to work out the cpu model you have put in cpu socket of the board.
Check the cpu support list for the board, and what bios version it needs to have in order to run the cpu model you have.

The board may need a bios firmware update to be able to function with the cpu.

The other cause to the constant boot loop can be incorrect power phase.
So it is important that the Eight pin 12v block from the psu is connected to the board.
The eight pin on your board is located next to the Dimm memory slots.

Iv tried reseting the cmos, i took out the mobo battery and put it back it, i also tried starting it up with nothing but the cpu and fan in, i still get the same result. turns on and then turns off again 30 seconds later then turns itself back on again.
