MSI Z77A-G45 - Motherboard burns trough on the USB connections

Hey,
I recently bought the MSI Z77A-G45 and installed everything, works perfect, for about 3 weeks, then my USB's stoped working. i send it in for repair, they send me a new one with the note the old one was burned.
Installed the new one, works perfect, then a week or 2 after, same problem comes back and I actually smelled the burning this time.
Has anyone else had this problem with this card?
Greetings, Sam

>>Posting Guide<< please list you components?
that is not normal and never heard about the USB 3.0 burning with leads me to first think BAD PSU what is it?

(msi z77a-g45 motherboard) A disk read error occurring

For the msi z77a-g45 Motherboard
I'm getting the "a disk read error occurred press ctrl+alt+del to restart" error when booting in my new build.
I have recently switched out my 4gb stick of g.skill ripjaws ram for 4x2 gb sticks of 1333mhz ram. I have not done anything besides this and i just started getting this error. I tried each ram stick individually and they boot but i get the error. I tried the 2 and 4 dims and still get the error. I tried re-seating the sata and data cables to my optical drive and hd.
The only thing i can think of is that i was installing a windows update just before i left to go change the ram so if that could be an issue please let me know.
Thanks.

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

MOVED: MSI Z77A-G45 Motherboard Overclocking/BIOS help!

This topic has been moved to Overclocking, Undervolting.

BUMP
Oh yeah, so not only can i not overclock my pc anymore, it's decided to crash on me every 30 minutes, doesn't restart.. I've tried using a different PSU (Same 750w, different brand), I've tried it with one stick of RAM and the other, Taken the graphics card out, re-applied thermal paste on the CPU, All temps are fine (I don't have to be playing games, i could be sat idle and it will still turn off)...
I was originally thinking it's the PSU that's failing but now i'm thinking it's my motherboard. Thankfully i'm replacing it soon, but this has been a very trying period.

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 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 z77a g45 I/O Shield

i just bought a msi z77a g45 motherboard and it didnt come with a io shied and was wondering were i could get one.ive look on ebay but i cant seem to find one.

Quote from: Nichrome on 06-January-15, 03:31:25
The board itself is good. But for I/O shield it's strange.. did you buy it brand new or used?
Contact seller, or ask MSI:
>>How to contact MSI.<<
used.i got it at a what i think is a good price.i contact both seller and msi so one of them should know.so the board is a good one and should last?this is my first ever msi product so i dont know alot about them and this is also my first upgrade in about 5 years from a old e8400 system

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
for your reference a full parts list:
Motherboard: MSI Z77A-G45

OS: Windows 7 64bit Ultimate

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
Intel i5-3570 CPU
Coolermaster Hyper 212+ EVO
8GB Crucial DDR3-1600
EVGA 560Ti 448 Core Classified (Primary)
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.

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!

Help with OCing my MSI Z77a-G45 gaming with i7 2600k

Hi there its been awhile since ive done OC since my old intel e8400 and everything looks different now..i just recently bought a brand new Msi Z77a-G45 gaming MB and i7 2600k for good deal and would like to push my limits on this setup
Currently setup:
intel i7-2600k
8gb ddr3-1600 gskill ripjaw X Model F3-12800CL9D-8GBXL
MSI Z77a-G45 gaming motherboard
Antec Hcg-750 PSU
Evga gtx670 single card
my old rig Corsair H50 for now waiting on my custom built water cooling
i know i tried using the OC genie to test out their OC setting which gave me 4.2ghz with 1.336vcore and friend told me thats kind of high for a 4.2ghz?
any help will be good step by step. my goal for now is to reach like 4.4-4.5ghz until i get a better cooling system

Alrighty, appreciate the info; gonna back down to 4.4Ghz as I can maintain stability with 1.275 vcore in bios = 1.26 in windows = 1.24 under load resulting in hottest core never exceeding 70...was really hoping for 4.7-5.0Ghz overclock when most everyone who reviewed this chip in the early days was claiming such great overclocks with such low voltage. But I'll chalk that up to either misinformation or non stability checked overclocks, I guess I'm old school; cause if it can't hold up to a minimum 24hr pass of Prime 95 small fft's it isn't stable in my book. Might consider delidding it in a year or so once the new wears off, I had my i7 920 for about that long before I lapped it into a mirror shine lol. So based on my new information 3770k's on average overclock between 4.4-4.6Ghz and can require up to 1.4 vcore and higher past 4.6Ghz which is where you start to really become thermally limited on liquid as the Ivy Bridge's 22nm technology puts the cores to closely together in combination with intel's cheap ass thermal compound solution. Maximum recommended voltage for 24/7 shouldn't exceed 1.4 vcore without some kick ass cooling or a combination of delidded processor and kick ass cooling cause ideally you want your cores mid 70's and below...that about sum it all up?

MSI Z77a-G45 graphics driver issue.

02-june-2013
MSI Z77a-G45 graphics driver issue.
Trying to install the graphics drivers for this board from the MSI site, I but every time I do so on loading windows 7 my monitor just goes to sleep and I have to roll back the driver in safe mode. This is the same for the driver found in the windows 7 updates.
Iv downloaded the files a few times over and reinstalled windows twice and the problem remains. Can anyone suggest anything? Is there something I’m missing or need to set in the UEFI bios for using the onboard graphics?
MSI Z77A-G45, i5-3570K, 2x 8GB Corsair memory, Windows 7 64bit.
Thanks.

My BIOS is E7752IMS V2.10
Iv already downloaded V2.A
However I have to say the guide at uk.msi.com/service/biosupdate/ , appears to be putting v2.2 on top of v2.2.
it also says "Download the BIOS that matches your motherboard and version number to your USB device."
I'm not entirely sure what is meant by 'version number' but it dose suggest i need to download V2.10 not V2.A ... call me picky but i want to be sure! lol.
Can anyone confirm ether way? It dose seam rather odd!
Thanks.
**edit
Update on my graphics issue
With the default driver, just before the windows 7 log in screen appears. I was getting a portion of it appear first on the bottom 1/8 of the screen. Now its appears to be a snowstorm of bad graphics and its the same when I switched to using HDMI instead.
Not sure if that's a good sign!
For reff my screen is a HP LP2475w tho I'm rather sure there is nawt wrong with the screen.

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.

Urgent need of assistance, MSI Z77A-G45 Thunderbolt Unknown problems

Recently I have built my first computer, a desktop with the MSI Z77A-G45 Thunderbolt motherboard, an Intel core I5 CPU and a NVIDIA Ge-Force GTX 650 TI Video Card, and a 850W PSU (way more than what is needed). The computer worked perfectly fine for about a week, I did not initially order a Disc Drive because I figured I could install windows with a flash drive (which apparently does not work) so I installed ubuntu for a while (irrelevant to the problem) I ordered the Disc Drive and when it came in I plugged it in and the computer would not turn on, so I spent a while trying to figure out why it did not turn on when the day before it worked fine, eventually after basically disconnecting almost everything and putting it back together it worked. But it had no signal to the monitor. I have no means of telling if it is a UEFI/BIOS problem, a video card problem, or a CPU problem. All 4 LED's for the CPU phase are constantly on, when before when the computer worked fine it would only have the first phase LED blink, so I believe it might possibly be a CPU problem, though the video card is what controls the output for monitors so it equally could be the problem. For the motherboard I tried just about everything to reset it, everything, except flashing the BIOS (which I don't want to try unless it is the only solution left) I tried to clear the CMOS, took the BIOS battery out and put it back in again. Please help!

I do not yet have access to another desktop in which to put my graphics card. I just tried reseating everything and still no signal to the monitor. The VGA port on my motherboard does not work, it never has for some reason, I did not get intel integrated graphics with my CPU, I am not sure if that is why the VGA does not work.

Msi z77a-g45

Hello,
I got a new build with a msi z77a-g45, Intel core i5 3570k and 8GB corsair 1666 DDR3 and a MSI 560GTX TI
this is not my first build so i went for it.
after i put it al together it did boot up and just kept running without giving me any form of beeps and my screen stayed black.
i went to troubleshoot some things and it all didn't help. after an hour i found out that when i push down on the (stock) cooler on the right corner it would boot up ( the phase leds all turn up) and when i let it go it just shuts down immediately. same goes for when i push down on the right corner of my gpu it would boot and when i let go it shuts down. i dont know what this is. i replaced the cpu for another one and this didn't help either. i also went for another cooler ( scythe mugen 3 ) still the same problem. i now fixed it with some tie wraps to pull it all down and it starts. do you guys have any idea what this is? i obviously want this fixed and I'm not sure if this is a rma problem or not. i also tried it out of the case ( on the desk ) to put down only the motherboard, CPU and gpu.
thanks in advance,
Wessel van Waas

You have a damaged CPU socket, and the board should be RMA'd.
