Computer Wont Post, Boot-Device-LED goes on then off

Hi i've been trying to fix my pc for a wile now and this is were i'm at.

when i turn it on everything goes fine fans turn on the different lights flash but no post.

The concerning light is the Boot-Device-LED it stays on for like 10-15 seconds than turns off but still no post

i've already RMAed my motherboard and Cpu so i don't think its that and my GPU's fans spin like normal

  1. "i've already RMAed my motherboard and Cpu"
    Then try borrowing a graphics card and make sure that the monitor and video cable do work.

    My monitor works fine i've tested other monitors and i get the same results.

    i dont know where to borrow a graphics card would it make since to buy a cheap card just to test
  3. Try borrowing one from a friend. A local PC repair shop might also help.
    Or try buying one that you can return, if issue not solved.
    It could be also that the power supply does not provide enough power to the card.

    so i just tried that and i don't have a boot device LED anymore when i start up my pc no lights turned on but still no post i then turned it off and started it again but this time the GPU LED was lit for 18-19 seconds i'm going to buy a new cheap Graphics card then

    Update: ok so i was thinking, i'm getting mixed results with different LEDs could it be my power supply isn't providing enough power?

    Yea u should check battery also. Try doing this without battery... once u take it away and unplug all power, waiting 10 min proceed with the same... Also there are jumper that u can try with. The idea also is reboot ur BIOS. This is the best fix ive got till now for red lights

    So i don't think it's my BIOS because this is a brand new mother board.....

    and what did you mean by heat sink

    i think that i may bring it to a shop over president's day break.
