i just build a new comp and i turned it on for the first time. my motherboard lit up 4 diagnostic leds which means system start then it went to 3... which means cpu deteced... after that it goes to 2 which means ram detected... but once it does that the cpu fan on the heat sink stops... then it goes to 1 led which means vga detected and then its supposed to not light up any leds which means system boot. i diddnt leave the computer on for long because the cpu fan stops.... what do i do?
