Z77A-GD65 Error 55 / Power On Loop

Woke up this morning and my Z77A-GD65 wont boot.. Powers on then restarts in a continous power on loop.
System has been working fine for last 3 months and has not been overclocked
Error 55 = no ram detected
Tried three different sticks of memory  all from different vendors and all ram slots and the same problem persists.
Tried a celereon g540 and still the problem persists.
Have resest cmos via onboard button and by taking out the battery and problem persists.
Power supply is working fine on other system..
Ram Cpu Vga  hard drives are tested and are working in other systems just fine
Any Ideas ??

Test with a single RAM stick in the DIMM2 slot, disconnect all HDD's and ODD's, remove any external devices other than mouse and keyboard. Will it POST now? If not, with power off, connect the OS HDD, switch to the backup BIOS chip and see if it will POST and boot the OS.
Here's how to fix the BIOS chip if it is corrupted;

  • Z77A-GD65 Error 55

    Hello!
    I am new to this forum since I haven't had an MSI mainboard before.
    So I bought this pc this xmas and it has been working fine, since today...
    I was using it as normal and was gonna try the Super Charger program to charge my iPad. Activated it and powered off my pc. Tried to see if it would charge my iPhone while it was powered off and then I turned the pc back on again. This time it started for a short moment and then shut down again as if I made some change to the bios settings. And after that it was stuck in an infinite loop of rebooting.
    I was looking at the debugging console and noticed the Error 55.
    Tried with only 1 ram installed in every slot also two at a time in 1-3  and 1-4 slots.
    But no luck. The pc won't boot and I don't get a POST screen.
    Also tried without any ram installed at all, then I get another error, 20 or 22 something.
    Tried resetting CMOS and using the secondary bios thing on my motherboard, but nothing works.
    Is the mainboard broken?
    Really appreciate some help!
    Thank you!

    No bent pins on the cpu. Tried all the mem's individually in dimm2 but no go :/
    So could the conclusion be a faulty mainboard?
    Called the computer store I bought it from today and explained it to them, so they want me to send the whole computer so they can see what the problem might be :<
    Did you check the cpu or Socket? You would want to check the pins in the socket with a bright light and magnfying glass.

  • Z77A GD65 - Error "d7"

    Hello
         I have MB MSI Z77A GD65 with Intel 2500K. It worked fine, but I was on vacation for one week and after my return, it dont want to boot. (During vacation, I turned off my PSU and unplugged electric cable from wall.)
    After I push power on button, monitor signs no signal and MB stuck with code "d7". After it, I need to push power button for 5sec and it shut off. It will eventually boot up on third - fifth attemp everytime. I tried to unplug everything from board, leaved only PSU, CPU and one ram module, but still same result, it will boot 1 time from 5 attempts (average). Is it clearly for RMA or what should I try?

  • Z77A-GD65 Intermittent Power Up Issue

    Ever since I've had this board, it's been problomatic getting it to start at times. Most of the time it starts just fine, other times the fans just barely spin and it fails to start. Repeatedly pressing the start button usually gets it going after maybe a dozen rapid pressings (think Morse Code).
    I've tried jumping the pins on the header on the board, no difference. I've tried pressing the power button on the board, no difference.
    Sometimes, however, repeatedly pressing the power button does not get it to start. These times I have to disconnect the power cord and wait for the power button on the board to go out, usually takes 30 seconds or so for the board to totally discharge. Now it will power up right away, I have the BIOS set to power up after a power loss.
    Of course I've tried the usual things like one stick of RAM only in Slot 2, different sticks of RAM, only one GPU, no GPU, check for shorts to the case, properly seated CPU, etc. But as it is an intermittent issue, it'll seem fine for a while then go right back to not starting, then start right up the next time without any issues. It will always start with a CLEAR CMOS, but that is not a very handy method of booting the computer.
    The system is very stable after it is running, which leads me to think the individual components are not faulty. It never has any problem establishing a restart, only a cold boot. The HEX readout is always A0 when it's running, it's never had any problem booting up after it establishes power.

    What is the ME version in bios?
    If you remove the OC does the problem go away?
    I'm at work right now, not sure about the ME version. Can you elaborate what that is?
    OC has no effect, it's been doing this since long before I even attempted to OC anything. It's a fairly random issue. I could, for example, take the OC out and maybe it'd boot issue free for a number of tries, I'd think the issue was resolved. Then, without changing anything, it'll go back to doing it. I had this happen when I read that RAM slot 2 was determined to be the primary slot. I loaded one stick of RAM into slot 2 and got several clean starts. I was convinced I had resolved the issue, only to have it fail on the next attempt.
    One thing, time appears to be an issue. I can play around with it in the evening, make multiple cold boots no problem. Then it won't start up in the morning. Or maybe it will start up in the morning, but not at lunch. Or not in the evening. But if it's just a couple or a few minutes, it'll start. And restart.

  • [SOLVED] motherboard MSI Z77A-GD65 error code B2

    hello,
    I recently installed an MSI Z77A-GD65.
    Here is my config:
    - MSI Z77A-GD65
    - I5 2500K + Noctua NH U12P-SE2
    - KINGSTON Hyper X 1600 Mhz DDR3 4 x 2 GB
    - 2 x SSD VERTEX 3 and 4
    - POV GTX 660 Ultra Charged 2 go
    - WD Caviar 500 GB
    - Supply CORSAIR GAMING GS 600
    - Case CM HAF932 advanced
    I searched all the forums I have not found anything on my problem is the following.
    at the first start (after installing the hardware) I got a black screen with the little bar at the top left flashing in the bottom right and "B2" then a black screen with the same small bar but not flashing. On my motherboard I have a set of code that runs and stops at B2. No BIOS.J 'tried everything:
    - Move the graphics card
    - Exchange up memories, play with the colors of slots, try with only 2 bar, try with 3 instead of 4 memories
    - Disconnect the SSD and the HDD, change the connections at the plug SATA, try with HDD only
    - Clear CMOS
    - Start without devices connected (only with keyboard, mouse and screen)
    - Check all my connections and CPU + Noctua
    NOTHING .......................... I do not understand

    Reading A0, it is at the point of OS loading. A0 is not an error.

  • Z77A-GD65 error 55 after running for 5 months just fine

    Hi,
    My Z77A-GD65 has been running perfectly since last May with a 3770K, G.Skill 8 GB DDR3-2133 Quad-Kit and a Antec EA-550 Platinum PSU.
    Now the PC reboots continuously with error 55 showing on the mainboard.
    Two weeks ago I installed a new GPU, Geforce 660ti. After some initial hassles, it was working just fine.
    Things I have tried:
    - Removed the GPU, No go.
    - Removed all memory but 1 stick in slots 1&2. Repeated this with a different stick. No go.
    Probably something broke, but not the 'bent pins' issues I see reported when people see a 55 error, as my system was running just fine.
    Can anybody give a hint what broke and what should be replaced?
    Thanks for the help,
    J.

    Thanks for the hints, but still no go...
    Things I did:
    - Cleared the CMOS according to the guide, actually several times, but no go.
    - I borrowed a spare 650W Be Quiet PSU from a friend, but alas, I still see the 55 error.
    Does this then point to a defective mainboard or the CPU? From the documentation I get the impression that 55 means that the CPU can not be started.
    Is this correct?
    Thanks for the help,
    J.

  • MSI z77a-gd65 error 55 with 4 DIMMs installed

    While I did find another thread similar to my issue mine is a little different as all slots are functional.
    https://forum-en.msi.com/index.php?topic=158224.msg1162108#msg1162108
    If I install 4 DIMMs the board shows "55" on the debug LEDs. If I take out any two DIMMs (slots 1,3 or slots 2,4) the system boots fine and is completely stable. I can also have either pair install to either set of slots. I also made sure the memory timing, voltage, etc. where set correctly in the BIOS.
    Any suggestions?

    That it works when slots 1 and 3 or 2 and 4 are used, points to a problem an updated UEFI/BIOS may or may not resolve. Recommend to contact MSI Technical with your findings and see what they recommend or have to say about it;

    Well it appears to be a problem with the RAM. I just happen to be building another system with an asrock board and 16GB of G.Skill RAM. swapped RAM into my system and the G.Skill works perfectly in my z77a-gd65 board with all four slots populated. The Corsair RAM produces the exact same behavior when install in the asrock board. I'm just going to RMA the RAM.

  • Z77A-GD65 Error 55 constant boot loop

    I'm very confident the Board itself is dead. I tried all the usual suspects one stick of ram, CMOS reset etc. etc. finally resorting to replacing the motherboard with an old Z68A GD65 which booted faultlessly first time. Just confused why the board would suddenly report an error like this after running faultlessly and with no changes to the bios or the PC itself since I bought the unit it was flashed some months ago to the latest bios version with no problems. I need to check if I can RMA the board but is it really worth the time?

    Well, if board doesn't work while another board works with all the other components it is pretty surely faulty. Of course you can then go for rma.
    In Europe that takes contacting reseller.

    Hi Froggy,
    Thanks for all the suggestions, really appreciate it.
    I think I must have been updating my signature when you viewed the post if it wasn't showing up. I am getting by on integrated graphics for the time being so could I OC that a little too?  The memory is Samsung Green DDR3 2 x 4GB but I've not re OC'd it yet whilst trying to ensure the CPU OC is stable first.
    I found an old screenshot from my OC on BIOS v10.5 where I had the Spread Spectrum disabled so I think that has been the main thing causing instability this time around at achieving 4.4GHz on BIOS v10.6.  I've not used the Enhanced Turbo before so am not sure what that does, am coming from a very old non msi motherboard that used an Intel 440GX chipset.  Is the Enhanced Turbo the feature that OC's just the one core?  I've implemented some of these changes that I've highlighted in green and been running P95 for around 4 hours without any bsod, or threads in error.  CPU-Z mainly shows a core voltage of 1.176 or 1.184 and my temps on the hottest cores have maxed at 60c.  Will it be possible to go any higher than 4.4 but still retain the power saving of throttling back to 1.6GHz on idle?
    Disable EuP 2013
    Change Internal PLL to 'Enabled'
    Enhanced Turbo to 'Enabled'
    Disable 'Spread Spectrum'
    Try VDroop at 100%
    Digital Comp Level change from 'Auto'
    Core Expander change from 'Default'
    Leave Core Switch as is
    Change I/O to 1.07
    SA to 0.970
    PLL to 1.82-1.84
    PCH 1.055-1.061
    C-State either 'Disabled' or if want to keep it, change package limit to 'No Limit'
    Long 'D' (W) change to 250
    LD Maintain (s) to 60
    Short D (W) to 250
    Primary (A) leave alone
    Secondary (A) to 60
    Primary Turbo (W) to 250
    Secondary Turbo (W) to 250
    Other notes; I always 'Disable' C-State, and 'Enable' C1E Support when doing a Turbo OC with EIST to take full advantage of those power saving features they provide. 

  • Re: Z77A-GD65 Intermittent Power Up Issue

    Hey JRAuger,
    I have the exact same problem as you: I have the same motherboard and the same BIOS version (although I had the same problem before updating, and nothing is overclocked). I RMA:ed my first motherboard and received a new one from my supplier, but the problem persists. I've bought a new PSU and tried replacing every component with ones I know for a fact are 100% OK.
    The computer still boot loops. Once (and if) I somehow manage to get it to POST, the system is as stable as could be. I've successfully run Prime95 and Memtest86 for hours without reboots or errors. Once the computer has successfully started it will an can both shut down and restart without any problems. However, it seems if I leave the computer off for a couple of hours, the problem reappears. I have no idea what's going on but it's starting to get quite irritating.
    I've already breadboarded the computer once to rule out short-circuits caused by the chassis. To me, it sounds like a BIOS update provided by MSI is in order...

    (Same board btw)
      I too had this problem after I installed my custom WC loop. My PC would boot up for 5 seconds or so and then shut down and cycle this process. I moved my ram in all the slots and it didn't work and someone hinted that I try only 1 stick of ram. Well sure enough 1 stick of ram in DRAM1 booted the PC up just fine. I switched that stick for my other one, (2x4GB Mushkin 1333MHz Blackline) and it too worked fine. So as far as I know my ram sticks are good. Now mind you when I first got this PC months ago and built it both ram sticks and slots works in sync of each other just fine. After sitting torn apart for a few weeks as I was case modding, etc, the system started boot cycling. I've come to the conclusion that both ram sticks are good but that my board doesn't or stopped support dual ram. If I had more ram I would try it with all 4 slots but I only have the 2 sticks.
    When I boot with 1 stick I get post code A0.
    When I boot with 2 sticks in I get post code error 55. (Early Memory Initialization) *Not sure what they mean*
    I've tried CMOS reset, I have taken the battery out of the board and jumped the JP1 or w/e pins. I am about to flash bios and see about updated but now my windows is barfing so I have to reinstall that too. Grr!!!
    So!
    1. Try your ram with just one stick in slot DRIMM-1
    2. Call MSI and see about a replacement as I think your board may be bad too.

  • MSI Z77A-GD65 Code 55 perpetual loop?

    Afternoon everyone, long time lurker, first time poster. Unfortunately with bad news, last year I got the bits and pieces for my new gaming/work PC. Put it all together and it was working 100% until about a month ago.
    Went to boot it up as usual and it went into a perpetual loop, booting for a few seconds then restarting and doing the process again. Hopefully I've filled my signature in correctly with my system details.
    I tried the paperclip test on the PSU, all fine. Moved the RAM around on each slot and it still didn't POST. Got some working RAM off a friend and did the same, no luck. Moved the GPU to the other slots, no luck, card fans still spin if that helps.
    Let me think what else I've done! I rang the suppliers of my computer gear and they said to send the i5 CPU back. It was sent to the manufacturer by them (RMA) and I received a new (different serial number) yesterday. Fitted the CPU this morning and we're not working still!
    I've got a video of my boot loop if posting that would help?
    Would this be a board RMA now?
    Thanks for reading, Alan.

    sounds like the board has gone bad so i would say RMA the motherboard back to MSI!
    if you can borrow a known working PSU off a friend thats similare specs wise or better then yours to rule out the PSU has given up from a defect (it may work but something may have gone bad there possibly "maybe its +12v rail isn't pumping out hardly any amperage for some reason" or try yours on there computer to see if it works correctly as all the paper clip thing shows is its powering on)
    if you can do that and it works then a RMA of the motherboard would be the most logical next step!

    Sorry, didn't realise it wasn't preferred to keep feedback over a similar issue in the same thread.
    I seem to have solved this now at this 4.4GHz OC by slackening the memory timings to 11-11-11-24 Command Rate set to Auto and 1.565v DRAM Voltage.
    Still appears to be a problem though when raising the OC to 4.7GHz as fails Prime 95 blend testing even with the RAM set to auto settings (1600MHz), whereas the CPU appears stable according to Prime 95 small ffs.

    switching off the PSU
    trying a boot for discharge the board
    switch on the PSU
    and after 2 or 3 boot attempt with the "19" code

  • Z77A-GD65 Wont Boot Without Clearing CMOS. Gets Error 32.

    Hi!
    I just switched GPU from 2x 7950 to 980.
    I cleared drivers etc etc and was powering down my pc for the replacement. took out the cards and put in the 980.
    When i later was trying to boot, i got debug error 32, which is early cpu initialization. So i checked all the cables and tried again. Same thing.
    Took everything out and reinserted it again. Same error. even tried the to take out each ram to see. Still nothing.
    I later cleared cmos and the computer booted. but then when i restart i doesnt boot until power everything down and clear cmos again.
    Do you guys have any idea?
    My specs are

    Tryreplacing battery. Also could try to run it with single Ram stick and outside of the case.
    I Couldn't wait so i went to town and bought me a battery, didn't change anything.
    I've tried running a single RAM in each slot, just to try. no change there. Still error 32.
     I've also test it outside the case now and still no difference.
    Otherwise i've noticed i can boot if i press the reset button exact when debug code 55 shows. It's really weird. doing this way all bios settings are still there and i can test my pc with OC. I've played Dying Light on it this way with no problem at all. except this annoying code 32 who reappers everytime i restart my computer and hinders it to boot...
    EDIT: Also sometimes (very rare), it starts at first boot.
