    Unhappy Gigabyte ep45-ds3l won't boot

    As the thread title states i have just bought and installed a new Gigabyte ep45-ds3l to replace my failing 965p ds3p but the damn thing will not post, no beep, no bios screen , nothing, just a blank monitor.
    All the fans work and the lights on the board light up but thats about it.

    I have read about people with similar problems with this model due to their type of ram but not sure how to solve it. I'm wondering if the problem is my crucial ballistix 2 x 1 gb 5300 667MHZ or the board itself?

    Has anyone else had any issues with this board?

    It's always best to test your setup BEFORE you install it in the case. This eliminates the possibility of your mobo having a short circuit with the computer case. I place my mobo on a cardboard box next to my computer, with the necessary cables hooked up to the motherboard. Before you remove the mobo, double check that all connections are correct and fully seated.

    1) Turn off your computer.
    2) Unplug the power cord from the back of the power supply.
    3) Disconnect all cables & and wires from the mobo.
    4) Remove the mobo from the computer case and place the mobo on a box next to the computer case.

    Minimal setup:
    Do NOT connect your hard drive, mouse or ANY other peripherals to the mobo. It will help if you can connect a speaker to the mobo. Bios beep codes are found near the end of the User's Manual in the troubleshooting section.

    5) Remove all memory sticks from the mobo, leaving only 1 stick in slot #1, nearest the cpu.
    6) Connect the 24 pin main power connector from the psu to the mobo.

    7) Connect the 4 or 8 pin ATX_12v connector from the psu to the mobo.
    If this cable is not properly connected, ligits and fans will work, but nothing else. Don't ask how I know about this.

    8) Connect your keyboard to the mobo.
    9) Connect the graphics card to the mobo and your monitor.
    10) Connect the ON/OFF and RESET wires to the Front Panel Header.

    The problem might be with your graphics card. If there is a problem with the graphics card, there is a specific beep code for this type of error.

    11) Plug the power cord in to the psu and turn on your computer. If it boots, go into the bios, load OPTIMIZED DEFAULTS, then save the settings and reboot.

    11a) If nothing happens, unplug, swap memory sticks and try again.

    12)Re-enter the bios, go to the M.I.T. section and ONLY change the DRAM VOLTAGE to the memory's rated setting, usually 2.0 - 2.1 volts. Save settings and exit.

    13) Unplug the power cord again from the psu. Press and hold the ON button for several seconds. You might see a momenty flash of the computer lights.

    14) Install the second memory stick in the appropriate slot, usually slot #3.

    From here on, you'll boot, see if it works, turn it off, unplug the power cable, add one component at a time, test and repeat until you find the component or connection that is failing.

    Once you're up & running, do an extended memory test using MemTest86+ to verify that you don't have faulty memory.

    Good Luck.

    Hi profjim,
    I have tried most of your recommendations including a change of psu and another graphics card but still no luck.
    I also tried one stick of memory but the problem continues, also there are no beep codes so i cannot narrow the problem down.

    The only thing i can surely recommend is testing RAM sticks from another brand, Crucial is the RMA champion.

    I had a similar issue, with Corsair Dominator, i bought a pair from Revision 4.1, and later from Revision 5.1, if these sticks are mixed together, my mobo won't even post.
    So i bought sticks again, from Rev 5.1, and all four sticks works correctly, OC'ing and everything else.

    I have ordered OCZ 4GB (2x2GB) DDR2 800Mhz memory which should arrive tomorrow, hopefully this resolves the problem because if not i think i will just return the motherboard.
