    Default Gigabyte GA-EX58-UD5 Won't boot or post

    Hi,

    Just built a new rig this week. When I switch it on, it doesn't even get as far as loading the BIOS. I get the leds on the board to light up. Fans start spinning then it shuts down. Then it starts up again. Then it shuts down again.

    I can get it to stay on if I remove the 12v ATX CPU power cable, but obviously that not a useful solution!!

    So far I have tried the following so far and each time it still gets stuck in an infinite reboot cycle.

    1) Removed all connections to the mobo and reconnected
    2) Removed memory sticks
    3) Removed video card
    4) Removed CMOS battery and left it our for a while
    5) Tried a replacement PSU
    6) Inspected and reseated the CPU (its a very tigh fit, but others seem to have the same experience)
    7) I tried holding the clear CMOS switch down with the machine off and when it's on. When it's on, it just makes the lights stay lit and the fan run until I release the switch. Then it starts all over again.
    8) I have taken the whole rig apart and run it on the bench to check for shorting

    I have:

    GIGABYTE GA-EX58-UD5 ATX Intel Motherboard

    CORSAIR CMPSU-850TX 850W Power Supply

    Western Digital VelociRaptor 300GB 3.5″ SATA 3.0Gb/s Internal
    Gainwind NVIDIA GeForce GTX 295

    LITE-ON CD/DVD Burner Black SATA Model iHAS324-08

    Intel Core i7 920 2.66GHz LGA 1366 130W Quad-Core Processor

    XIGMATEK Intel Core i7 compatible Dark Knight-S1283V 120mm Long Life Bearing CPU Cooler
    OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Voltage Desktop Memory
    COOLER MASTER COSMOS 1000 Silver Computer Case

    Thanks for your time.

    Hi,

    Just a thought but the UD5 has 2 mainboard power connectors are they both connected?

    1. The main large 24-pin power connector (top-right side) as you look at the motherboard
    2. The smaller supplimentary 8-pin 12V ATX connector (top left of the motherboard as you look at it)

    with a power hungry GTX295 card I would think both of these would have to be plugged in. Consult your mobo and power supply manuals to select correct cable to attach to correct plug.

    I am not sure whether I understood you correctly but I think it is wise to only hold down the CMOS clear switch whilst the power is OFF not when the PC is on and powered.

    I am presuming that you do not hear any beeps because you say the PC does not post, correct?

    Thanks Howard

    Both power cables (24 and 8 pin) are plugged in to the mobo. I also have 2 PCI-E plugged into the video card.

    No beeps when it powers up. Agree about the CMOS button, I just am trying anything to get this rig working.

    Ok

    Am I correct in thinking you are using the Board as it came out of the box with no updates to the BIOS?

    1. If you have an i7 920 processor does it have D0 stepping? You can tell because a thing called the sSpec number should be SLBEJ and can be checked either on the retail box label or the processor itself Processors - Processor Spec Finder: How to Find your sSpec Number

    If you do have an i7 with D0 stepping your motherboard BIOS version needs to be F6 or greater as F6 contained a fix for compatability with these processors, latest version is F9m. GA-EX58-UD5 (rev. 1.0) - GIGABYTE - Support&Download - Motherboard - BIOS

    So you may need to flash your BIOS with latest version (see flashing guide in these forums).

    2. Check your front panel connectors for Leds, speakers, power on/off and reset etc. I have known incorrect connections here to prevent posting.

    If 1&2 look good then try booting with a minimal setup ie

    CPU +cooler
    1 stick of RAM in the correct slot
    1 Graphics card.
    PSU
    BIOS optimised defaults loaded, make sure RAM, Graphics card, cpu cooler and memory are well seated in their slots/sockets

    If no post and shutdown/startup cycle persists try the other stick of RAM in the same slot

    see how that goes, maybe somebody else will post some ideas in the interim

    good luck

    Its only ever gets as far as flashing 88 before it power cycles again

    Howard,
    It is a D0 stepping CPU. How do I flash the BIOS if the machine won't get as far as getting BIOS up? Tried pressing DEL, but machine cylces again before it gets to BIOS.

    I am following this thread since I have the exact same problem with a P55A-UD4P (although I do not have a CPU and Video Card yet - I expect some sort of an error message but not constant recycling of the power)

    its not the bios,it will boot up with the factory bios installed usually f7 bios mine had no problems,id say its hardware related,either ram/psu/mb or chip its just figuring out which part,did you say you tried with one stick in first white slot from cpu socket??? did you try one stick in the other two slots? it should boot from any white slot

    PSU - tried 2 different ones
    RAM - tried each of 3x2Gb OCZ in white slot nearest CPU
    CPU - I have inspected and reseated and it seems fine
    Mb - Not sure how I test for a faulty Mb?

    What puzzles me is why it does not power cycle when I remove the 12v ATX power cable to CPU. Obviously it doesn't boot like this, but does that help?
