Z77A-G43 GAMING Bios Issue

Hey all, i'm wondering if anyone else has had this issue or any suggestions for repair. My motherboard is just over a year old and it seems the bios has packed in on me. I don't want to chuck it because I do like this board with my hardware configuration. Before I go any further I would like to say it is definitely a corrupt bios issue and sadly this board only has the one so I cant swap to bios 2. So my question is this: is there a way to flash the bios without being able to POST? The computer currently cycles through the power up process and shuts down after about 1 second which starts again after about 5 seconds and repeats this pattern until I pull the plug.
Any Help would be greatly appreciated!

Well, I had several problems with the machine over the past few days, The computer keeps failing to post and so I reset the bios as per the manual and all was well again but as soon as I restart the pc, I get the exact same problem. no post and have to reset the bios. This went on for several attempts at rebooting until now it just wont boot and resetting the bios isn't working. I know all other aspects of the setup are working because I have tested them so its the only logical conclusion.
if the computer worked before like you said a year + with the same BIOS,
and you didn't change anything to the BIOS before this happens
then its not BIOS issue, BIOS can't broke by itself

Is there no way to get the board to copy a new bios from USB stick or something?
placing the BIOS stick over USB key
but i don't think that will makes any difference

  • Z77A-G43 Gaming boot issue

    Alright, I'll make this as concise as possible as this board has, quite frankly, tried my patience all week.
    However that's another story for another time, to my current issue!
    The situation: I've recently bought a new mobo, CPU and RAM and in the process did a fresh Windows install just to clean everything up. No problems there so far. I have downloaded a game from a digital platform this afternoon and so, due to the fresh install, installed the official driver for my Microsoft controller. The restart dialogue box pops up as per usual and I close down what I'm doing and restart. I wait for my PC to boot and...it doesn't. It now just hangs at a black screen with a flashing cursor. (This screen comes after the splash screen, just in case it's relevant)
    The things I have tried thanks to Google-fu: I have removed all of my USB devices that are plugged into my PC.
    I have disabled legacy USB.
    I have changed the boot order, even making it so that my hard drive was the only enabled bootable device at one point.
    I have cleared the CMOS to use default settings.
    I have used a single RAM stick in Slot 2.
    I have attempted the flash a new BIOS using Mflash, however Mflash doesn't detect any BIOS files on my USB.
    I have tried to boot using a BIOS on my USB stick. They're detected, but then an issue pops up about the system data map being different from the BIOS data map so it won't boot.
    None of the suggestions above have gotten me past the flashing cursor. Has anyone else got any ideas? I'd like to not have to return the board as that would leave me without a PC for a few days, but if I have to then I have to.

    Sorry, I realised that more information would be required so I returned before checking out for the night.
    CPU: i5 3570K (stock speeds)
    PSU: XFX Pro850W Core Edition - Overkill now, but I had big plans when I ordered ha! Mice and men...
    RAM: 2x4GB of Corsair Vengeance (running at 1333MHz at the moment as that's what the mobo defaults to until XMB is turned on/voltage increased)
    Windows HDD: Seagate Barracuda 1TB
    GPU: Gigabyte 560Ti 1GB OC Edition
    OS: Windows 7 Home Premium x64
    I can't think of anything else that's relevant at the moment.
    Yes, it is the MS Xbox Wired controller (I tried to not use other company names here as I know some forums don't allow it).
    I had a look at that before, but the installer gave me the impression that it is to be used on the system you are trying to flash to, and therefore need to boot into Windows for it on the actual machine to then update that machine.
    The issue I had before was that the system was just not overclocking. I spent two days doing a huge amount of research trying to get my multipler to stick, but CPU-Z would always just report a stock speed so I returned my mobo to it's stock settings to make sure nothing went wrong by accident and decided to just try again at another time when I had more time to figure it out and play around. I read an obscene number of different posts from different forums, and each one had differing information but none of them worked.

  • MSI Z77A-G43 Gaming Crossfire

    Hi there,
    It´s my first post here so greetings all  I have a question regarding MSI Z87 G43 GAMING motherboard and crossfire. I noticed, a bit too late, that the G43 does not crossfire in a x8/x8 mode! Is this a performance compromiser? I mean, I´ve noticed a great scaling in BF4 with seetings in High (no AA; with SSAO) running the game with a 3 screen display - compared with single card I went from 50-80 FPS to 70-130.
    So, if I understand correctly from the board specs, I have one graphic card at x16 and the other x4?
    Thanks for your attention.

    So... I´ve been searching other MSI alternatives towards minimizing the cost of my ignorance. I found MSI Z87-G55 - 3 PCIe 3.0x16. The price is 30€ less than the G45 (110€ vs 140€) and the only visible diference is the network adapter (Realtek® RTL8111G Vs Killer E2205). Can you tell me if this is a good choice?
    My specs:
    Core i7 4770K
    Gskill 2*8GB 1866
    SSD Samsung 840
    ASUS 7970ghz DCII Top
    PowerColor R9280X
    Also checked the G55 OC Genie feature in BIOS. I´m currently using that with my G43 and it´s very simple efficient and absolutely stable and trouble free. Is the BIOS in the G55 similar to the G43? Hope you could answer all this m8... sorry for such inquiry :P
    Thanks again for your attention 

  • MSI Z87 G43 GAMING -BIOS CRASH-

    Hi everyone ,
    I got a z87 g43 gaming mobo  I try tried to update my mobo on the live update A40 to A50  then it stuckt
    Now no signal on monitor i tried to reset cmos by putting out  the battery but didnt work i dont understand what i need to do about jumper
    its something like that what can i do???
    Oh i almost forget my system is overclocked is it important and system resets itself(what is going on)   
    Other specs
    4x2 ram corsair
    4670k
    Gtx 760

    You have to return it to the seller if you want a replacement (LiveUpdate hasn't voided warranty as that was provided by MSI). Otherwise look around the city for repair center and ask if they can restore badly flashed BIOS on this mobo.

  • Z77A-G43 OC genie issues?

    Hi. I recently bought a MSI Z77A-G43 motherboard and i was trying to use OC genie to OC my I7 2600K. When i went through, put it into OC genie mode, then made oc genie bios controlled; the "Customize" screen for OC genie is completely blank? Any ideas? Thanks...

    When you set to OC genie mode it means that you are not allowed to do settings manually. If you think of it a bit closer the name is supposed to illustrate that the settings are being done by a genie.
    So EITHER you do all the OC settings manually (customize) OR you leave it to the genie (OC genie II)!

  • Problem with Z77A-G43 After bios updating

    Hi guys
    I purchased my main a week ago, the bus of my rams are 1600 but main detect it 1333. So i updated my bios of 2.7 to 2.10 with live update 5, after the updating progress finished my pc restarted, it doest give any picture and after 20 sec reastart again and again!
    I shorted the jumper, i brought out the battery but it didn't have any result. Please tell me a solution. And forgave me for my poor english. My pc:
    Msi z77a g43
    2*4gb 1600
    Core i5 3570k
    Sapphire 7790 dualX

    RAM defaulting to DDR3 1333 is common as the SPD profile of the chips is set for that. For 1600, either manual setting is required or X.M.P. can be tried if the modules have X.M.P. profile.
    Live Update bricked your board. Solution is to take the mainboard to a shop with an SPI flash programming device, or obtain RMA for an MSI Service Center, or contact your reseller for instruction.
    Next time you need to flash, do it the safe way;

    Does anyone know where I can get one of these in the UK, everywhere I look it says out of stock/discontinued..... I mean everywhere
    I have no choice to get a z77 version of the motherboard as im running an i5 3350p ivy bridge which is a 1155 socket.
    any help or location of this product would help.... I wish MSI would just sell their stuff too.

    Thanks for the reply I did see that one but I was looking for the red and black dragon emblem one, its seem everyone of these I find is somehow discontinued.
    prefer the red and black as its goes with the colours scheme I have also matches the 2 msi GPU's I have, just wondered if anyone knows of a UK retailers of this version
    As a side note the blue and black doesnt look as impressive XD

  • Z77A-GD65 Multiple BIOS Issues - B4 Hang, Splash Screen Blinking

    Back in November 2012, I built a home server with a Z77A-GD65.  Lately, I've noticed some strange things happening that I've been trying to research but to no avail.
    First off, I get the B4 code hang-up whenever I'm booting.  This doesn't matter if it's a cold boot or a reboot, it hangs on B4 for about 10-15 seconds, flashes 92 really quick, and then goes to A2 which it stays for another 5 or so seconds.  After that I get the MSI splash screen for about 1 second, then it blinks 5 times.  After that it goes into Windows just fine.
    The blinking is a new issue, the B4 hang is not.  I've read from multiple posts that this is a USB issue.  When I disable USB legacy support, the issue goes away, but of course then I can't have legacy support.  I have yet to figure out what exact device is causing it.  In the process of trying to figure this out, I updated BIOS to A.A0.  After updating to this version of BIOS the splash screen blinks 5 times before going to the "Starting Windows" splash screen.  This is a more difficult issue to figure out why it's doing this because if you search for "BIOS" and "flash" or "flashes" or "flashing", you typically get results for flashing your BIOS.   Hence, why I'm using the term "blinking".  But even then I can't really find a solution out there.
    I also happened to see that the website for the Z77A-GD65 is showing a newer BIOS version, but I'm unable to flash this (at least using M-Flash).  I threw it on a USB, re-enabled USB legacy and whenever I click on it to install, the BIOS screen hard locks.  The screen just freezes exactly where it's at in the BIOS and the mouse is dead.  However, I can CTRL+ALT+DEL on the keyboard and it will reboot the system so I don't need to power cycle the computer.  Not sure why this is happening either.  Perhaps I need to flash this a different way?  Maybe I don't need to flash this at all?
    I could really use some input here on why this is happening.
    As for the specs on my system, they're as follows:
    i7-3770K overclocked to 4.2 Ghz by using the Turbo Mode in BIOS
    32GB Komputerbay DDR3 PC3-12800 1600MHz DIMM with Low Profile Blue Heatspreaders Quad Channel RAM | 9-9-9-24 XMP ready
    AMD PowerColor 7870 Myst Edition GPU - currently not overclocked although overclocking this doesn't seem to affect any issues
    2 - 128 GB Corsair SATA III SSD - one runs the OS, the other I use to load games from
    2 - 500 GB Seagate Barracuda 7200 RPM Sata II HDD's mirrored via Windows 7
    1 - 750 GB Seagate Barracude 7200 RPM Sata II HDD
    1 - 1 TB Western Digital MyBook USB 2.0 external
    2 - 3 TB Seagate USB 3.0 external
    ASUS DVD Burner - not sure which one, it's a cheapy $20 from Newegg
    1 - PCI USB 3.0 expansion card
    Antec TruePower New TP-550 Modular 550W Continuous Power ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Active PFC "compatible with Core i7/Core i5" Power Supply
    NZXT Switch 810 gunmetal - currently have 4 fans running but plan on more, also the Switch 810 has the multi-card reader in the front with 1x SD Card, 2x USB 2.0, 2x USB 3.0
    for peripherals
    1 - Microsoft 360 Wireless controller adapter (legit one, not the knockoff although I had a knockoff prior to getting the real deal)
    1 - Logitech Wireless USB Keyboard with Touchpad
    I tried to be thorough.  Thanks in advance for any help!

    Probably a USB device problem.
    This is a candidate, as well as mouse and keyboard. Disconnect USB devices one at a time to find the culprit.
    A lot of devices running. PSU a +12V single rail or is it multi rail? A rail going to the graphics or components may not be enough amps. My best guess is the card reader.
    For UEFI/BIOS flashing, select your mainboard here and use the forum flash method;
    I'll definitely try unplugging some of these USB devices to see if that helps with the B4 hang issue.
    As for the PSU, according to the description for it on Newegg:  "Four industry-leading independent +12v rails are provided for more stable and safer power output."  It has two rails going to the GPU.  The GPU is a new addition to the system and so I wasn't running it until recently.  The issues were occurring beforehand, but you're right that this PSU is underpowered for the rig considering PowerColor recommends a minimum of 500w.  I'm going to be buying a larger capacity one sometime in the very near future.  Any recommendations on good modular PSU's?  What's a good way to tell what wattage to get?
    Thanks for letting me know about the forum flash method.  I'll be back later when I have some results.

  • Z77A-GD65 Gaming BIOS Update Problem

    An update to version 25.1 just appeared and when I tried to run it I got an error message saying it's incompatible with 64 bit Windows. This wasn't an issue with 25.0 and there wasn't anything on the download site about the new one being 32 bit only. Has anyone else tried to install this on a 64 bit system ? Because I've been getting some unusual error messages lately and I'm not sure if the problem is with the download or something on my system. Thanks

    I was hoping you saw my reply before you tried that other ME firmware update, as your ME was updated already. The ME firmware and driver are different entities, and they have different version numbers that do not match. That is not a problem.
    All you need to do is look in the UEFI/BIOS System Information and it will tell you what BIOS version is installed along with what ME firmware is installed. When in Windows, you can use CPUID's CPU-Z Mainboard Tab and it too will show the information. Again, the forum flash method took care of the ME firmware flash. There is no need to go through all that multiple flashing baloney. Too much risk involved if for no other reason.
    Did you download the newest CC utility yet? If still no luck, a ticket to MSI is recommended so they can work on an updated version for your mainboard.

  • Z77A-GD65 - Dual BIOS Issue

    Hey guys, I believe there is an issue with the Dual BIOS feature on my board.
    During some OC tests and changes, I experienced the following with my board:
    1. I applied OC settings which caused the PC not to boot.
    2. I switched to the second BIOS and the PC didn't boot - At this point, I should have been able to boot the PC with the second BIOS but nothing happened.
    3. I cleared the CMOS by removing the battery, the PC booted fine.
    4. I went into one BIOS, reapplied my old OC settings and the PC booted up fine again.
    5. I switched to the second BIOS again to see if it was on default, to my surprise, it had the exact same settings as the second BIOS.
    6. So today I tested again, I switched to the secondary BIOS and loaded optimized defaults on it, guess what? The PC didn't boot at ALL! On defaults!
    7. Switched to the second BIOS, and again, no boot.
    8. Removed the Battery again, both BIOSes reset to default.
    9. Reapplied my old OC settings again on one BIOS, PC booted up.
    10. Switched back to the secondary BIOS = SAME SETTINGS!
    At this point, I have no backup BIOS, any change I set changes it for both of them, when I move the switch all settings are completely identical.
    Either I killed one of the BIOS chips and they both act as one or my board is defective and it is not switching between them.
    How's this possible?!

     What ever solution you choose to cure the problem you should also notify the manufacturer so they can redesign the back plate, include spacers or whatever is needed in the future. Possibly they can offer a fix for you. I'm pretty sure they would be more than willing to make a happy customer out of you.
     I would use some nylon washers of some kind from a hobby shop or hardware store if it was mine provided there was enough space between the back of the MB and the case for it. Otherwise as you say trimming the back plate would be the only other way to do it.

  • MSI Z77A-G43 GAMING with CORSAIR Vengeance Pro CMY8GX3M2A1866C9

    HI,
    I need to know please if i can use this ram kit  ?
    if yes, can i get the max ram freq (1866MHz) by enableing xmp in bios ?
    cpu: I5 3550 Ivy bridge
    thanx

    XMP will not be found under CPU support. Its not a CPU function. Its a pre-defined memory SPD profile that can be used by board manufacturers as a BIOS feature. A sort of a one-stop shop to apply a certain overclocked memory condition.
    The RAM manufacturer will have predefined JEDEC SPD profiles programmed onto a EEPROM chip on the mem module. If its overclocked memory, then additional XMP profile/s may be added. This XMP profile can be applied by enabling the XMP feature in the BIOS. This enabling of the XMP then tries to apply the pre-programmed profile to the CPU memory controller. The mem controller may or may not work at this desired XMP setting. It saves you the effort of setting the overclocked mem profile manually.
    With Ivy bridge CPUs the mem controller can apply 1600 as default. Anything above that is not guaranteed.
    Thus if you have memory with a XMP 1600 profile, then its most probably 1333 memory with an overclocked XMP profile of 1600.
    XMP also will only become visible in the BIOS if the memory actually has a XMP profile.
    If your memory has a 1866 XMP profile, then that will be applied to the IMC, or at least an attempt will be made. The IMC may or may not work at that OC'ed mem setting. Further tweaking maybe needed, i.e. increased voltage to stabilise. Experience though shows that most of the memory controllers on Ivy will not have a problem with 1866.

Maybe you are looking for
