MSI Z77 MPower - Boot issues (A2 debug code and more)

Hey guys,
I've been trying to get my new computer build working but I have encountered several issues when trying to boot the computer.
Before putting everything inside my case, I tested the motherboard + CPU + 1 stick of ram to make sure everything was working. I had issues in the past where I had to remove everything once I had things mounted.
Everything seemed to work and I got into the BIOS and looked like everything was good.
I mounted it in the case with the same configuration and I was able to get into the BIOS again. So I thought everything must be ok.
Fast forward a couple hours later after I finish plugging everything in, I try to turn it on but it just gets into this boot loop.
Turn on > Fans spin for a couple seconds > turns off > repeat. This just kept going on and on and I wasn't exactly sure what was going on.
I started to unplug components and when I only had the Mobo + CPU + 2 sticks of ram in I was able to get into the BIOS.
I plugged things in one at a time and when I plugged in my SSD it would work.. but when I added another drive I would start getting the A2 Debug message on my board.
I would continually get this A2 debug message and I am not sure what to do to get it to work.
I have updated my BIOS to the latest ones and it is still not working.
Could this be an issue with my PSU? I really hope it's not the MOBO..
My System:
i7 3770k
CoolerMaster 212 Evo
MSI M77 MPower
16GB DDR3 Ram
7870PCS+ Tahiti LE
Corsair HX650 PSU

Quote
I've tested it with one stick and 2 SSDs and it doesn't give me the A2 debug code.
Do you have any different ram to test with?
What ram exactly are you using?
You may perhaps be able to set the ram timings in bios to JEDEC standard 9-9-9-24 1600 perhaps

Z77 Mpower boot issue - won't POST

Hi there
Got a question regarding a PC build that isn't working as well as hoped. Doing this on behalf of my friend but I've been helping him while he builds it so have a good idea of what's been going on.
Set up is as follows:
Processor: Core i5 3570k (stock, not overclocked or anything)
Motherboard: MSI Z77 Mpower
RAM: 8GB Corsair Vengeance memory (in 2x4gb)
PSU: Corsair 800W Gaming PSU
Storage: OCZ 240GB SSD
Cooling: Zalman water cooling (can't remember the exact model off hand I'm afraid, will try and get that later)
Graphics: HD 4000 integrated (for now, haven't got the graphics card yet)
We built the machine and got it going no problem. When it was first built it booted no problem, so we set up boot priorities and then installed the Windows 8 Enterprise 90 day trial. All good so far. Installed no problem at all at lightning speed and we got into Windows fine. Installed lots of drivers and so forth with no such trouble either. CPU was reporting a steady 25C average temperature on idle and everything seemed to be going smoothly.
Then we hit a stumbling block. We powered off the machine to make a minor adjustment in the case (all while static protected with a wristband), and after doing this we then powered the machine back on. We're now getting a dim red LED (almost seemed half powered) in the DrMOS overheat warning and then two bright blue LEDs next to it indicating the CPU power phase. The fans will spin and case LEDs come on, but nothing else happens other than that and the LEDs. No POST screen or anything like that. It might also be worth noting that now when you plug the computer in, the green LED on the internal power button no longer lights while the machine is off - when the machine was working it would.
I've spent hours trawling through the forums and can't seem to find the same problem happening. We're getting a bit worried that there could be a fault on the board but wondered if we could get some advice from here first. I tried resetting the CMOS with no avail and trying the other BIOS.
As a last resort, we've now removed the cooler and CPU to check the CPU hasn't melted or anything drastic like that and it's absolutely fine - no visible damage. We've left it like that for now until I can get back over there with some more thermal paste to reseat the processor and cooler so until then we're stuck anyway.
If anyone has any ideas or knows of the problem, it would be really appreciated as we're a bit worried! What should we try?
Thank you!

Many thanks, will give that a try. Is it an RMA to MSI if that fails then? Forgive me for not totally understanding consumer rights - but it was only bought around a week ago - could we get the supplier to exchange it or would it have to go to MSI for repair?

Next, remove the main board and place it on a non-conductive surface and test it with a single stick of ram in dimm 2, cpu & cooler. You can try switching the ram ram sticks and dimms, but the last few times I saw anything about the drmos alarm it was a defective mainboard.
While it is out and the cpu is removed though, take a good look at the cpu socket pins and count all the stand off to make sure there are not extras.

MSI Z77 MPower Ram issues

Hi guys
I recently installed the MSI Z77 MPower after replacing it with the Asrock extreme 4 mobo which i had before, am currently having problems with the RAM it wont boot if i place them in the correct slots for dual channel configurations but if i place them in the last two slots the PC boots up fine.
My Ram is the G Skill Ripjaw X series 1600mhz model number: F3-12800CL8-4GBXM.
Its driving me nuts two motherboards and nothing working, i just hope its not relating to my CPU or something like that.
Please...please guys really need your help with this, because without it running in dual channel configuration my first build feels incomplete due to this problem.
Thanks in advance

Hi guys thanks for the replies and sorry for the late reply has i said before my MSI MPOWER Z77 motherboard is totally brand new and i know for a fact that no bent pins in the cpu socket, from what i am aware of, if my RAM is related due to the type of RAM modules that i am using and you guys are suggesting corsair modules which ones do you guys recommend me getting. You know when i said only slot 3 and 4 only worked could that be in a result of the RAM am using or not....??
Thanks in advance guys

MSI z77 mpower boot loop-cold start

Just got this PC put together a few days ago and I havent had luck keeping it at 4.5ghz @ 1.360v.
System Specs:
i5 2500k
z77 mpower @ latest bios version
16gb Corsair Vengeance 1866mhz
msi GTX 670 power edition oc
750w Corsair psu
256gb samsung SSD
Corsair H80
I can get it overclocked to 4.5ghz @ 1.360v and while running prime95 for 24hrs it was 100% stable, temps never went over 70C. I have set the I/O voltage to 1.2500v, the System Agent voltage to 1.105, the RAM memory voltage to 1.60v. XMP enabled @ 1866 9-10-9-27.
The problem is that it runs fine until I shut it down for 15 minutes then try to boot it back up, it boot loops 5-6 times then resets everything in the BIOS. The motherboard shows a code 60 as soon as it powers up, then it shuts down again, then powers back up then it gets stuck on A2, then again shuts down and starts back up and shows 60 again, and then A2 again, does this 5-6 times until it decides to reset everything and it allows me into BIOS again. It's driving me INSANE. Does anyone know what the heck is going on? I want to be able to shut it down when I go to sleep and be able to turn it back on without overclocking it again in the morning, ya know?
It works perfectly fine when I restart the computer, only happens when it sits turned off for more than 5 minutes.
Appreciate the help in advance.

We have similar boards and I cannot view your screen shots: https://forum-en.msi.com/index.php?topic=162043.0
Try an overclock based off mine and see if it is better.
If you want to do an muliplier change oc, post better screen shots so I can see what you have set.
**PS: Don't mimic my ram settings, just enable xmp. Also, you won't be able to get this stable at 1866 w/ 4 sticks unless you are lucky. Esp with a Sandy cpu.
Do your testing with just 2 sticks in dual channel, then put the 4 in and if you are lucky you may be able to set it to 1600 9-9-924 / 2t.

Z77 MPower - Booting Issues

Currently, my display won't show any information when I turn on the computer.
The CPU cooler is working as intended.
The fans are spinning.What worries me, though, is the Debug LED. It's showing "FF". A code not mentioned anywhere. To the extent that not even Google wanted to help.
Components:
NVidia GeForce GTX 680 (Gainward PHANTOM II)
4 pieces of 8GM DDR3 2033Hz RAM (Corsair Dominator Platinum)
CPU Water Cooler (NZTX Kraken X40)
850W PSU (XFX Pro Series)
120GB SSD (Kingston HyperX 3K)
Intel Core i7 -2700K Second Generation
I tried the following troubleshootings.
Remove add-on cards:
I tried to remove graphic card. The same issue
RAM removals:
Using only one RAM. Blank.
Using no RAM. No change. Probably not a good idea either.
Checking CPU pins:
If anything, all the pins are bent. But neatly towards one direction. I suppose that came from inserting the CPU.
I did insert the CPU correctly, according to the indicators. Triangle mark on the CPU matching the mark on the slot.
I'm not entirely sure what's wrong. No clue at all. And I'm still curious about this "FF" code.

FF has seemed to indicate the board was bad in the past....
Before BUYING a new cpu, I would probably rma both the cpu and mainboard.

BOOT ORDER issue? MSI Z77 MPOWER + SSD Samsung 840pro

Hello
I have an MSI z77 MPower m/b - Intel i7/ 3770k and two hard disk drives...
First HHD (Samsung SSD 840PRO 256gb) connected on SATA Port 2.
Second HHD (WestedDigital WDC 2TB Green) connected on SATA Port 6.
The CDDVD is connected on Port 4.
The SSD has WIN7 .
The WDC 2TB, has 2 partitions. One with WIN8 and the other for BACKUP.
In the MSI BIOS under BOOT menu, i chose the HARD DISK DRIVE BBS Properties as shown :
Boot Option #1 Samsung SSD 840Pro
Boot Option #2 WDC WD20EARS-...
When I start my computer it usually boots on WIN7 from the SSD (1st choice).
The problem is that SOMETIMES after shutdown, the computers changes the BBS order and BOOTS on WIN8 from WDC.
When I re-enter on the BIOS the HARD DISK DRIVE BBS Properties is changed to:
Boot Option #1 WDC WD20EARS-...
Boot Option #2 Samsung SSD 840Pro
Can anyone help me with this boot issue?
Thanks,
Nikos

Other than updating the firmware of the SSD and mainboard: >> BIOSes<<
Use the disk management to make sure the boot partition of the WD drive isn't active.

If i boot up / run the windows 7 x64 install from the flash drive when its plugged in to the top 2 USB 2.0 ports on the back of the board it runs the windows install fine and formats everything ok but if i plug the flash drive in to the USB 3.0 ports it loads up but when it gets to the part what ask's '' which type of installation do you want '' upgrade or custom. i click on custom and it says
'' A required CD/DVD device driver is missing. If you have a driver floppy disk,
CD, DVD or USB flash drive, please insert it now.
Note. If the windows installation media is in the drive, you can safely
remove it for this step ''
I know the copy of windows on the flash drive is fine as it works in the USB 2.0 port and i have got the computer up and running but would like to know what the problem is and how i can fix it
Thanks

MSI Z77 Mpower Code A0, and wi-fi not detected ...

Hello, from about 20 days I use the new mainboard MSI Z77 Mpower.
My system is composed as follows:
MSI Z77 Mpower, PC1500 DDR3 1866MHz 16GB Corsair Vengeance
1.5V CL9 (2x8GB), CPU Intel i5-3570K 3.4 GHz, SVGA ASUS GTX660 TI, Samsung SSD 128gb 840pro.
I installed windows8pro in UEFI mode with ssd disk partition gpt.
As bios setup is everything default except xmp profile enabled for the Rams, and UEFI boot-legacy because I have linux in another disc.
It all seems to work fine, but I have a few doubts_troubles !
1) Sometimes in debug LEDs, instead of the temperature appears the code A0 ... is it normal or it indicates a problem ?
2) I've never tried the Wi-Fi, it is normal that it only works if the LAN cable is disconnected ?
The problem I had with wi-fi is that sometimes the sistem said that the hardware was not found or not connected ... I tried to install the latest drivers without any success, after several attempts, I think I found the problem ...
Wi-Fi is connected to the mainboard, I think in the USB port, and for some reason it does not make contact, after pulling back slightly the 1 mm. module it started to work.
If instead I press slightly forward, (the pressure that normally is used to attach the antenna) it loses the link ... Do I have to leave it like this or can I do something to resolve the problem ?
3) Normally the steps to open and close the PC are very fast, in some cases, the PC takes a long time to shut down, and once gave me the same problem at the start, after a long wait I rebooted and it started without problems .. .
Normally, the computer is stable ... Do I have to try the thorough ram test ?
I apologize for being longwinded and thank you in advance for the answers.

The wifi adapter is removable?
In case it is, without losing the guarantee.
If you give me confirmation, I try to see if it is just a matter of contacts.
I need specific instructions!
for now it seems to work properly.
If ask rma, mainboard or complete one module wi-fi?
Wi-Fi, it is normal that it only works if the LAN cable is disconnected ?
Thanks pikka68
No, the adaptor isn't removable. Perhaps I misunderstood, you were saying that when you hook up the Ethernet cable, the mainboard shuts off the wifi. You can check in the bios for an option in regards to this or it could be the OS I am not sure. If they are both working when needed, is there really a problem?

MSI Z77 Mpower error code "B2"

Hello,
I had just bought a Z77 MPOWER board to fit with my Core i7 -3770K.
When i try to boot i got the code error "b2" and nothing more...
Many people seems to had got the same problem, so i tried few "solutions".
When i downgrade my GPU card (7970 Radeon) to an old 8800 GTS, i can boot, but Keyboard and DVD and one of my HDDs are not activated (so i can't install MSI drivers from CD) the mouse works.
I had Already install the last BIOS from MSI support, that don't change anything.
I will be glad to get help , i barely going to send back all stuff to seller
and go back to Asus Board...
Thx for the help
Configuration:
Msi Z77 Mpower

1 x 256 SSD OCZ Agility Sata II

thx for your advice always nice to get a good advice
but as i had repair the original PSU i will save few bucks and keep going with it.
i go sleep i pray for new idear about the "B2" problem.
in anyway i will be oblige to contact my seller , i only have 10 days to change the board if i can't solve the problem :(
Good night all.

MSI MPOWER b2 or 62 debug code

I bought my 1st Mpower about a month ago and had to RMA it. I had/have the same problem as this user. https://forum-en.msi.com/index.php?topic=164766.0
I RMA'd the board because after hours of clearing cmos and swapping things around nothing worked. Now I get a new replacement and the same problem persists.
I have swapped the ram using 1 stick at a time, tried both one at a time. Cleared CMOS numerous times. I have had the board in and out of the case so not a grounding problem. I have tried on-board and and a GTX 560 gpu. There are 0 bent pins that I can see. CPU triangle is facing the correct way. My monitor says no signal and can't get into the bios (obviously). I also cannot tell if the debug led says a lowercase b2 or a 62, I assume it is b2.
Any help is appreciated this is very frustrating.

There will always be people with similar problems but that doesn't help you with yours. If no possibility to test cpu there is no other way but to rma cpu or board and to see if it was the right component to rma.
This has happened twice with two board and someone on these forums and someone on toms hardware forums with the same cpu (3770k) and same board as me with the same led debug code. That's not a similar problem that's the exact same problem.

PC won't boot. MSI Gaming 7 motherboard had a **debug code of 67**.
I ran Malwarebytes this morning, it found some stuff, I had it remove them and rebooted. Haven't been able to get my PC to boot since :(
When I begin booting, nothing happens at all on the monitors, the PC itself has power and it looks like it's on but I only get this error code 67 on the motherboard and that's it.
Really don't want to unseat the CPU for any reason to troubleshoot that. CPU is always a pain in the ass for me to remove and place back into a PC. lol.

try >>Clear CMOS Guide<< with power cord removed
Tried that, didn't work.
Unseated each RAM stick, didn't work.
Removed the CPU, cleaned off the thermal grease, reseated it, replaced grease and heatsink. Didn't work.
Literally unplugged and replugged everything in one by one and none of it fixed the problem. Still receive error code 67.
Have no damn idea what the heck is going on.

Msi z77 mpower. higher than 8gb = reboot loop. help.

Hey guys I'm posting this in hopes that maybe someone could figure out what is causing my new build to reboot loop without post if I added anything higher than 8gb of ram stick. I updated the bios to latest non-beta version, drivers all updated, and made sure that all connectors were correct and properly attached.
Here is my build:
i7 3770k
Corsair H80 liq.cooling
MSI Z77 Mpower Mobo
Corsair Vengeance 16gb (4x4gb) 1600MHz [9-9-9-24]
Asus Geforce GTX 670
Corsair AX850 psu
2 WD Black 1gb HD
Win 7 Ultimate 64bit SP1
Everything is at default options since I didn't want to overclock without including the full 4 sticks of ram. Whenever I add a stick into slots 1 or 2 while having a stick in either(or both) slots 3 and/or 4, and attempt to start it up, the mobo's debug shows 55(early memory initialization) and then gets stuck in a reboot loop. It boots up fine if I only add 1 stick in either slot 1 or 2 but if I add either a stick in slot 3 or 4 or add a stick in 2 while having a stick in 1, reboot loop occurs. I've searched everywhere for similar problems and actually did find one on this forums, https://forum-en.msi.com/index.php?topic=162331.0, except that the thread starter's problems were about getting the reboot loop problem after he has overclocked his system and nothing about the number of ram he has added.
fyi: the mobo names ram slots(from left to right) as slots 3, 4, 1, 2 (in case anyone gets confused reading what I have wrote above)
Some assistance would be greatly appreciated.

Honestly, it doesn't matter what slots are what number because I cannot add a 3rd stick (more than 8gb) without pc going into reboot loop and or any variations of dual channel setup without pc going into reboot loop.

Sounds like maybe the DRAM V. is being set too low by the BIOS. Raise it to 1.55-1.575v's and see if that resolves it.
using your #1 image, if i try to add stick in dimm1&3 or dimm2&4 it would reboot loop. If I tried 1&4 or dimm2&3 it would reboot loop.
If i tried dimm3&4 it would reboot loop.
BUT if I did dimm1&2 like I have it right now, it would boot up with no problems. I have already tried raising the DRAM V with no luck as well.

Z77 mpower mainboard giving me a code FF, but only sometimes?

I've just built my new PC and it's working almost perfectly except that sometimes when I switch it on all I get is code FF. But trying it again and it will come back as normal and give me no problems at all
I understand from reading posts that it's to do with the CPU and bent pins or an over-tightened heat-sink, but I've checked the board and cpu twice now with a magnifying glass and I can't see any problems in that regards. I've also tried adjusting the heat sink tightness. But I'm still getting this error, probably about 5 times out 10.
Main system specs are;
Intel i7 3.50Ghz 3770k idle temp is 34C
MSI Z77 MPower (MS-7751) updated to the latest BIOS
2x 8GB Kingston HyperX Blue dual channel DDR3 DIMMs @1600Mhz
Gigabyte GTX760 OC
Windows 64bit Ultimate on Toshiba 128GB SSD
My thinking is that it's a MB fault rather than the CPU due to it working perfectly once I get it to boot.
Any help would be greatly appreciated.

My best guess is the PSU may be going flaky. Double check all the connections, especially the JPWR2. What is the PSU by the way? Model, brand, specs, etc..
Hi, thanks for the response,
I've got an older model Enermax Galaxy 1000w modular PSU with two 12v CPU connections, 1 is an 8 pin the other is two 4 pins that can be connected together to make an 8 pin. I have tried both leads but get the same results. All connections are fully clicked in place. Hope it's not the PSU but I'll try a feed via the molex connector and see if that helps

Quote from: trist96an on 17-November-12, 05:02:46
but is that what cosing the problem? cus this other guy on this forum had the same problem and he had a good psu
we troubleshot your PC, not someone else machine.
also we can't claim part failure or to narrow down the issue,
since you don't meet the requirements with PSU.
with regard less if the problem is in the PSU or not, you need better PSU in all cases.

MSI Z77 MPower sound problem

I have MSI Z77 MPower and i have problem with sound. When i play audio i have feeling that sound automatically volume up and volume down. When i uninstall THX i have feeling that is everything OK but sound is not loud like before.I try on THX turn off smart volume and cristalyzer but problem is still here. Can you help me.

I had the same issue with an early version of THX, have you downloaded the newest version from the website?
>>MSI Downloads<<
Update all of your drivers and re-test. In my case I just un-installed THX until the next version came out and it's fine now.
