I got an ECS H61-H2-M17 today and paired it with my 2500k and 2x4gb ddr3 rams, when i press power button pc runs normally, fans spin and i get a screen saying press f7 to enter bbs popup or press f2 or del to enter setup but when i press any of them keyboard's light turns off and pc restarts few seconds after. İ already checked every cable and pulled out bios battery but it didn't work.
