Hi I've recently built my new pc (first build ever) and it is in some sort of boot loop. My build: https://pcpartpicker.com/list/zBsDV6 minus the 3tb hard drive it hasn't arrived yet

What I have tried (based on reading others solutions with similar issue but none were exactly the same):


  • removed gpu

    removed m.2 ssd

    reseated cpu, couldnt see any bent pins

    tried different ram slot combinations based on m/b manual

    removed one ram stick

What happens:


    I flick the psu switch and my motherboards rgb lights flash once then turn off

    I press my case power button

    my red cpu LED on motherboard flashes instantaneously/cpu watercooler fans and case fans turn on

    dram red LED on motherboard turns on for a few seconds

    dram red LED turns off and vga LED turns on for a few seconds (even if i take out the gpu)

    cpu fan and case fans turn off, no more error LEDs on motherboard (i think whole pc powers off)

    back to step 3.
