MSI z77a-G45 Infinite Reboot Loop

Hello,
Here are my system specs:
Core i5 3570K
Hyper212 Plus
Intel 330 180 GB SSD (with OS on it)
WD 1TB Black (for data)
MSI z77a-G45 motherboard
G.Skill Ripjaws 8 GB RAM
EVGA GTX 660 FTW Signature 2
Corsair TX650m PSU
Lite-on iHAS124-04 Optical DVD Drive
Corsair 200R case
I should mention the following up front: I don't know what is causing my problem, but my guess is it's either PSU or motherboard.
Nothing in my system is overclocked (except for the fact that my GTX 660 card comes factory OC'd). Here is my issue. Yesterday, I shut down my computer and everything was normal. I didn't change anything at all. Today in the evening, I tried to power on my computer, and it simply goes into an infinite reboot loop. I don't see anything on the monitor, nothing comes up. The computer powers on for about 10 seconds, and then powers off for about 5-6 seconds, and it keeps repeating this process. Actually getting this process to stop is a bit tricky (I think I have to hold down the power button for several seconds when the computer is off). Does anyone have any ideas? I've tried a few things, like checking to make sure the 8 pin and 24 pin cables are tight. I've tried resetting CMOS and taking out the CMOS battery. Ideas? Thank you.

Hi guys. I know this thread is 2 and a half months old but I need to find a solution to this problem. It may have been better to start a new thread, excuse me for not doing it as my problem is quite similar.
Well, my situation is a bit different and I will explain it shortly but first I'll give you my PC specs.
MSI Z77A-G45
Intel i5-3570
Corsair DDR3 8GB (2x4)Kit 1600MHz Vengeance
Nvidia GeForce 9800GT
So when I assembled my PC I put one RAM in DIMM2 and the other in DIMM4. This led to an infinite reboot loop. The fans and the leds were working but nothing was displayed on the screen. After doing some tests removing and inserting again the RAMs with different combinations I came to the conclusion that this infinite reboot loop is occurring when a RAM is inserted either in DIMM1 or DIMM2. My PC works fine if I connect the RAMs in DIMM3 and DIMM4 but not with the DIMM1-DIMM3, DIMM1-DIMM4, DIMM2-DIMM3, DIMM2-DIMM4 combinations.
At first I thought one of my RAMs might be corrupt but after the tests I see that both work fine and I'm starting to believe that the Motherboard has the problem.
Any ideas? This is really frustrating.

Msi z87 g45 infinite boot loop

Hey everyone, i just purchases all my new components including msi's z87 g45 motherboard. When trying to start the computer it turns on one second and then off again, and that goes on until i turn off the psu. I tried a lot of things like different RAM sticks and different dimms, and even with only the cpu and psu attached to the motherboard it still does the same:( Now ive read a lot of things, but at another forum i read that the i5 4670k is only supported by a bios v1.1 My g45 motherboard says it has v1.0... So cud that be the problem or shud that not matter? suggestions please :(
My system:
i5 4670k
z87 g45
xfx pro 650w
crucial ballistix 2x4gb
msi gtx 770 lightning

Clarify what board you have. Is it Z87-G45 GAMING? If so it lists 1.1 is required indeed. None the less it has been released with Haswell and the first release Haswell cpus (like 4670k) should be supported with any bios out of the box (even 1.0). I doubt that bios version could be the problem as it would be impossible to flash then as there is not even any older cpu that is officially supported with 1.0.
Try reseating cpu and check socket for bent pins. Also try running board outside case with just basic components.

MSI Z77A G45 boot loop

Hi everyone!
I just tried to flash my MSI Z77A G45 today from the bios version 2.1 to 2.A.
I had blackscreens all the time when i tried to flash it with the M-FLASH utility from my bios.
Then everything just started normaly (after each blackscreen), but there wasn't any update, i tried to force the update with LiveUpdate.
And now when i try to start the computer, i just get a blackscreen (no signal for the monitor) and a boot loop.
It just stops and reboot after 10s.
My hardware is working perfectly, i think this is from a corrupted bios issue.
Which things i tried:
- Doing a clear CMOS (nothing happens)
- Removing the CMOS battery for 10 minutes (the reboot loop stopped, but there was not any display, i restarted the PC then and the reboot loop started again)
- Cleaning my PC (from dust and things like that), it was not efficient at all
- Booting from a USB key with the bios in, and formated as FAT32, nothing happens too. It doesn't recognize the USB key and anything else (keypad etc.) so the blackscreen was there again.
My Hardware:
CPU: Intel Core i5 3570 3.4 Ghz
Motherboard: MSI Z77A G45
GPU: None (Intel graphics 4000)
RAM: 2x4Gb Corsair Vengeance
HDD: Crucial M4 SSD 64Gb
Power supply: Corsair 850W
Do you think that i need to send my mother board back to the RMA?
I hope you will be able to help me, or find a solution
Thanks in advance

You can try the steps found here https://forum-en.msi.com/index.php?topic=119375.0
Otherwise, it is RMA time.
Next time use the forum flash tool and archives found on the forums.

Msi z77a-g45 - BIOS not saving loop

Hi there, I picked up a msi z77a-g45 and an i5 3750k, 4x4GB Kingston RAM, etc etc.
I'm an experienced system builder, but this is my first build in i5 land, or actually on an MSI board. The issue I've got is when I first booted, it shows the "CPU or memory changed !!" and to press F1 for setup or F2 to load defaults and continue. Cool, expected on first boot. I enter setup, get the BIOS how I want it, save and reboot, it immediately shuts my box off and 2 seconds later, back on. All good so far.
But it again prompts the "CPU or memory changed !!" warning. Err...it showed my CPU properly in the BIOS, same with memory.
I've now gone through it quite a few times, and it always re-prompts me to go into the BIOS again or F2 to use defaults.
Doing the F2 deal will get me into Windows, but upon reboot I get the error again and have to F2 again just to boot.
I've tried using Click BIOS to make changes, it however doesn't show any memory in here (updated to latest Click BIOS version), but does show my CPU fine. Shows 0GB.
I've also updated my BIOS to release 25 this morning, no change.
Anyone else have this happen at all? I suppose my next steps will be to drop to a single stick of memory, see if that goes, or do a full 'remove battery' cmos clear. I've tried pushing the clear button on back of mobo but didn't seem to do anything.
Would really appreciate any ideas, thanks all!

MSI Z77A-G45 and Samsung 840 Series weirdness

Ok so here's the thing
about a week ago i decided that it was time to build a new computer with a Z77A-G45 motherboard
put it together, installed windows 7 64-bit and everything was working just fine - for about 5 days -
but then one morning when i turned on my computer it decided not to boot and just sat there with fans running with an A2 code at the bottom left of the screen
i tried taking out the ram leaving just 1 in and moving it to different slots and trying a different ram block boots thinking it might be faulty ram,
when that didn't work i tried removing the graphics card and boot with just the onboard VGA, reset the CMOS jumper, and even replaced that battery on the motherboard thinking the shop might have shipped an almost dead one, took everything apart and booted it outside the case on a glass surface to make sure it wasn't some sort of short
but the only time it actually wanted to get past the A2 code was when i booted with only 1 of my hard drives, so i started changing my drives around using various combinations of SATA cables and ports (luckily had an extra 5 SATA cables lying around)
eventually i narrowed it down to it wanting to boot with 2 of my 3 drives but the 3rd one (a Samsung 840 series 500 GB SSD, that has no system files or anything fancy other then music, movies and a few games at the moment) getting it stuck on the A2 code
so i set it up as an external USB drive with a SATA/USB converter i had sitting around but then it would get stuck on B4 instead if i booted with the drive connected
however everything would work just fine if i connected the drive after the system had booted up (or even just unplugging and replugging it when it got stuck on the B4)
once back in windows with the drive connected i ran all the diagnostics i could think of but nothing showed anything wrong with it
(and the only thing i had done with the drive before it stopped wanting to boot was to defrag it)
eventually i decided to copy all the files from the drive to a different drive and reformat it as sort of a hail-mary
and to my surprise that actually made it boot up just fine
so i moved it back inside the case as a normal drive just to make sure it would still work (which it did) and then moved all the files back to see if any of them were the culprit - that turned out not to be the case however
it booted up without complaint with all the original files on it
so now my question is why?
what the heck is going on?
did defragging cause some sort of data fault that caused the bios to not be able to read the drive properly or did i just buy a haunted computer?
like i said everything is back in the state it was the day before it didn't want to boot and bios and been defaulted so it's not really an issue at the moment but I'd still like to know what's going on so i can hopefully avoid it in the future
any answers or comments will be appreciated

This is strange
I have Z77A-G43, and have exactly the same problem with one 1GB sata drive, that works just fine in every other PC.
In my case PC run into restart loop, but with same code A2 as yours.
Strangest part was PC was restarting even if I put HDD into PCI Sata/Raid card !?
So I am guessing here its not a hardware problem, but a software (BIOS) problem.
Now whole pc with Z77A-G43 is at Service because of faulty DVI output (not working).
Will try reformating drive, but need first to buy >1gb hdd to backup that one
Drive is currently working just fine in this 10y old MSI PC =.=
It seams they have stopped making things as they used to, this old mb is one durrable dog.
which was the main reason I went to same company when in question was mb...

MSI Z77A-G45 RAID Issue

Greetings...
Just got a new MSI MoBo and wanted to RAID1 my two WD Caviar Black HDDs. However, everytime I enable RAID and reboot it goes to a black screen with two "Z"s randomly placed in the middle. Once I get to the "black screen", it will only boot to that screen afterwards and needs a CMOS reset to fix. I have tried everything I can think of, but always get the same results. I have successfully installed Windows 7 on one of the drives with AHCI mode enabled, and have also had IDE mode work fine... but as soon as I enable RAID - black screen.
Everything else on the board seems to be fine. Anyone have any ideas?
SYSTEM:
MSI Z77A-G45 mobo

XFX 260GTX XXX Ed. (Physx)
2 x WD Caviar Black Dual-Proc HDDs
LG DVD Super-Multi Burner
Silverstone Decathalon 850W PSU
Windows 7 Home Premium 64-bit

FIXED - Ended up reflashing the BIOS, which restored the RAID utility. BTW, my G15 keyboard would not register the CTRL-I to get into the utility... I had to use a PS/2 keyboard, which required a CMOS reset in order to recognize. Just posting this in case anyone else runs into this.

Z77a-G45 Random Reboots

I'm having a difficult time trying to determine why my machine is so unstable. Under any load at all, and many times without me even working on it the machine will reboot. I'm happy to provide any details or additional information that may be needed.
CPU-Z Results
I've run the data lifeguard utility for my hdd. I've run bluescreen view to try and get a handle on it. I've run a repair on the OS more times than I care to admit. But still the problem persists.
Bluescreen view shows a 124 which as far as I know has something to do with processor or memory? Maybe memory voltage?
If anyone can help provide additional idea's I'm open to them.
Thanks in advance.

PRS-T1 stuck in infinite reboot loop after failed firmware update

Hi,
I tried to update the firmware, but failed when updating to version 1.0.07.05070. Tried to 2 times. The first time it failed I simply tried again. The second time, it took a lot longer to reach the failed to update message, but it did cause the ereader to reboot.
Now, it's stuck in an infinite reboot loop on the "Opening book" page. The progress bar on that page stays completely empty, lasts for about 30 seconds, and reboots again. This will go one until the battery is dead or indefinitely if plugged in.
I have tried pressing the Home + Menu buttons, but they seem to have no effect.
Please advise if there is anything I can try to revive it?
Thanks in advanced.
David
Solved!
Go to Solution.

Kiroken,
Here is what I have observed:
- After a hard boot (reset + power button during 3+ seconds), if I don't do anything, it will reboot every ~30seconds.
- If I press and hold the Home and Menu buttons, no effect. The same as if I didn't press anything.
- If I press the Forward + Back buttons (2 & 4), it does not reboot after 30 seconds. Instead, the orange light on the power button blink every ~2-3 seconds.
- Any other key combinations that I have tried have no effect.
I have tried with and without several rescue sdcard. No difference. No improvement. In every case, the computer never sees the reader. If plugged into the power outlet, it seems like the battery charges alright. It does not appear to charge if plugged into USB port.
That's all I know. If I can't fix it, I might be forced to turn it into a coaster or maybe a cutting board for the kitchen.

MSI Z77A-G45 Crossfire

I am planning to buy the MSI Z77A-G45 motherboard. Only i see the manual say:
Quote
Slots
■ 2x PCIe 3.0 x16 slots
- PCI_E1 supports up to PCIe 3.0 x16 speed - PCI_E3 supports up to PCIe 3.0 x8 speed
■ 2x PCIe 2.0 x1 slots
Can you tell me if this motherboard does fully support 16 lanes on both cards in Crossfire?

No, it can't. It will switch to X8/X8 if using Crossfire. Due to technical limitation Z77 can't go X16/X16

MSI Z77A-G45 SLI

Hi, guys. Can somebody say to me. Does SLI realy works on my mainbord MSI Z77A-G45? On the my mainboard I saw "SLI ready", on the official site MSI I saw SLI ready too. But in the Basic Specifications on the site MSI I don't see "SLI". Please help me to find truth!

Even the product site lists SLI also in Basic Specifications (http://www.msi.com/product/mb/Z77A-G45.html#/?div=Basic) as it says "SLI - Y" and Y means Yes.
Overview also lists SLI: http://www.msi.com/product/mb/Z77A-G45.html#/?div=Overview
So yes, Z77A-G45 supports SLI in a X8/X8 configuration using the Gen3 slots.

Intel Core i5-3570K + MSI Z77A-G45 turbo OC @ 4.5GHZ Problem

Hi Guys,
Maybe you can help me out. I'm currently running turbo OC @ 4.4ghz stable. When I set the Turbo ratio to 45, i always fail the prime95 test or get bsod. Below is my hardware and bios settings:

MOBO: MSI Z77A-G45
RAM: G.Skill Sniper F3-12800CL9D-8GBSR (4GBx2) CL 9-9-9-24-2N 1.5V XMP
I followed most of the settings from xmad/Froggy Gremlin on this post - https://forum-en.msi.com/index.php?topic=164847.0. Any other settings I can tweak? Or do I need to go manual and set the vcore voltage to 1.3+?

MSI Z77A-G45 Motherboard Overclocking/BIOS help!

Hello everybody
I've been having quite a bit of trouble with my MB/BIOS being unable to push the OC beyond 38/3.8GHZ and the RAM won't go further than 1600MHZ.. Now i was able to do this before (Had a stable 4.4GHZ with 2133MHZ RAM speed.. i'm not quite sure what's stopped me from being able to OC more than these stated values, however in ClickBIOS i can OC higher than i can in the BIOS menu on startup itself but the settings don't apply correctly
I have a I5-3570k CPU, MSI Z77A-G45 MB, Crucial Ballistix Elite 2x4GB 1600MHZ, MSI 560ti GTX

MSI Z77A-G45 can't install window 7 by raid 0

I have a rig which:
CPU: Core i7 3770k
HDD: Two Western Digital 1 TB 7200
Main: MSI Z77A-G45
Power supply: 700W
Ram: 32GB DDR3 1333 MHz
*** VGA card: MSI Geforce nVidia GTX 660 Ti 3GBDDR5 TF
After configuring BIOS to setup RAID 0, I was trying to install Window 7 on my 1.8TB ( which was summed of two HDD )
But I got a problem about couldn't install the O.S on.
***And about the VGA, whenever I plug it in my mobo, my monitor shows black screen as it doesn't recognize the VGA card. What happen if I install window then add the VGA card later? Will it affect on my system later?
And what should I do to install RAID 0 with my stuff? I appreciate all supports.
Thank for read and answer my topic!

The 660ti will require a bios update to use most likely.
Is the system stable enough to flash? The forum flash tool included memtest, run this an so long as no errors or crashes, go ahead a flash to the most recent bios.

MSI Z77A - G45 - CPU multiplier problem

Hi,
I recently bought this PC:
Intel Core i5 3570 k
MSI Z77A - G45 - with BIOS V 2.5
Seasonic S12II-620 620W
Corsair Vengeance Low Profile White 8GB (2x4GB) DDR3 1600
Amd HD 7850
My problem is following:
If I change CPU Ratio (multiplier), in standart mode to 40x and leave CPU core voltage auto, it cause instability, even if use Cpu core voltage 1.25 V for ratio 40x.
But that's not all problem. I could understand, why I cant OC my CPU, but this instability is even if I change multiplier to 30x from default 34x and this makes me uncertain.
Now I will describe you that instability...
OK so, when I change ratio to 40x or 30x it doesn't matter, it runs to windows successfully but after using windows something about 3-6 hours pc turns off.
I also discovered second problem by coincidence. If I hit F11 (Boot menu) , when I am starting pc and I have set ratio 40x or 30x, I can choose what I want to boot only for 10 secs and after that PC restarts by itself....
But if I set default 34x ratio I can choose what I want to boot forever and pc doesnt restart.
I know that boot menu is not some test of stability but it is very strange... Why If I change multiplier, it doesnt matter, if it is higher or lower then default settings it just cause instability ? :-/
Thanks for help.

Quote from: xmad on 19-August-12, 07:02:15
I was just saying that the beta caused a vga problem, latest release the f11 problem so try the release prior to that, but if you got it working don't touch it! lol
Are you still using the beta bios?
No clue, we are just users like you are, just keep checking the website. You should report the troubles you had with 2.4 to msi too.>>How to contact MSI.<<
Yeah iťs working now. As I said, I wanted flash older Bios 2.4, so for sure I click on restore defualts in bios (for sure before flashing) in that 2.64 Bios version...
PC restarts and my graphic card started working =)...
So now I am running on that the latest Bios as you refered mi (2.64 beta).
I am running some test of stability on @ 4 GHz with 1.070 V (IBT,Prime,memmaxx,linx,cinebench,occt,super pi, 3d mark) temps are 62 C max...
So I guess it's ok now =)
At the end I have one question :
My Cpu is now running on 40 x ratio all the time, there is no some underoverlocking ratio (16x etc.) when it's in idle. I was thinking the Ivy Bridge overclocking is overclocking of turbo only...
I know It's detail, because I have good temps even in idle with 40x ration (33-39 C) but i want to be assured if it is ok.
EDIT:
And btw I didnť have 2.4 bios flash on, I wanted put them on... But before flashing my 2.64 beta started working right with HD 7850 as is wrote upper.
I had Bios 2.5 before 2.64

MSI Z77A-G45 & Sapphire Radeon HD 7850?

Hi all, I have purchased the MSI Z77A-G45 Mainboard along with a Sapphire Radeon HD 7850. I just finished my build yesterday and got windows 7 professional installed without a hitch. This was using an HDMI cable to connect my monitor directly to the mainboard. For some reason, my computer cannot detect my video card (7850). Under device manager, it shows that the display adapter is a standard VGA. I know the video card is working because I just tested it on a friend's computer and it ran perfectly with drivers installed. I looked on MSI's website for the compatibility table and saw that the 7850 was missing from the list for the G45. Does this board support the sapphire 7850? Or do I have to buy a new board? I really like this board and got it at an awesome price so I would hate to have to return it but changing the board would be a cheaper option than changing the video card (which was purchased on line). Any input is greatly appreciated. Thanks in advance!
