  1. Carefully remove the motherboard out of the case. Place it on a non conductive surface, such as a phonebook or cardboard box. Have just the cpu/heatsink, one stick of ram, video, and keyboard installed. No optical or hardrives yet. Connect the power supply leads to the board and video card if required. Remove the ps from the case if it won't reach. Then use a flathead plain screwdriver and touch the pin cluster with the power switch lead until the system turns on. Use a "f" key listed on the post screen to enter the bios. Change the boot order to cd>hardrive, set the ram voltage if needed (check your ram specs on the label or the manufacturer's website), then save and exit. After you turn it off, carefully reinstall the board inside the case, but first check the backplate and make sure it's square with the case and any extra metal is bent out of the way so it doesn't interfere with the device wires you install. And move all extra case and ps wires out of the way before mounting, tieing them down if necessary so they don't make contact with the board circuitry under the board.
  2. cpu phase 4 blue lights
    memory phase 1 blue light
    sys phase 1 blue light
    hdd 1 red light
    tried using only one memory stick and
    GPU changed to xfx hd 3650 and xfx hd 4670(instead of sapphire hd 57700cuz it doesnt have integrated
    is it because i m using wrong ram gskill(compatible with icore7 1333 1.5v-1.6v
    itnstead of 1.5v ram
    and wut r the reasons of not initialize cpu
    cuz ff error = power on initialize cpu (how to do that)
    any solutions
  3. thnaks for the help its working now
    ff means fully functional that means board is functioning
    i couldn't start it because of lose screws i guess after reinstalling to the case it starts perfectly my first pc done now assembling one for my brother thanks for your help
  4. Hi. Could you give me more information on how you fixed this? I have almost the exact same build, same mobo and processory, 2x2gb of g skill ddr3 pc1600 ram, and a 700w power supply.

    Ive never installed it in a case, breadboarding it on a phonebook, cant get any post.

    Even with just the cpu and heatsink on it, makes no post beeps. Tried two different video cards (ati 5850 and an old nvidia 7600gt that I know works) nothing on screen. Tried 1 stick of ram in each slot, no difference.

    Also, the CPU doesn't seem to be heating up at all. Even after messing with it for an hour, i took off the heatsink and the cpu was ice cold.
