Z77A-G43 Computer Reboots after Shutdown Issue

I recently built a new PC using the MSI Z77A-G43 motherboard and installed Windows 7. Everything seems to work fine except one thing - the PC immediately restarts itself after It shuts down through the normal Windows shutdown process. I have read many forums on this similar problem and have tried a few things such as 1) unchecking automatic restart in the system properties dialog box. 2) Changing the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon "PowerdownAfterShutdown" to a '1'. 3) Updated Windows fully as well as installed the latest drivers for everything. 4) Made sure that in BIOS all of the Wake Up Events are set to Disabled. In fact I even changed Wake Up Event By [BIOS] to By [OS]. 5) Cleared BIOS by taking the battery out for 5 minutes, as well as updating BIOS to the latest version 2.2. 5) The only IO card is the graphics card and I switched that out too and it did not make a difference. None of these options seems to correct the problem. I am convinced there is something wrong with this motherboard. Has anyone else had this issue with this or another motherboard? Anyone have any other solutions?

Sometimes a short within the chassis can caused such issue as well.
I suggest that you try booting and shutting down the hardware out of the chassis and see if you can replicate the issue.

Toshiba A300D rebooting after shutdown

Hi !
I've a bit problem.
When i shutdown my toshiba, it reboots after 10 minutes. It's very annoying, if i forgot to remove the batteries, he is overheating in my bag until i realize it is on.
Someone on the ubuntu forum have had the same problem :
http://ubuntuforums.org/archive/index.p … 73326.html
But his fix does not work for me...
IMPORTANT: i'm still trying, but I suspect that after completing the procedure, turning off the pc will not work properly anymore: infact the pc STARTS UP AUTOMATICALLY AFTER SOME MINUTES!!! :lolflag:
NEWS: the computer after installing bluetooth when is turned off, automatically powers up after a random time: the solution for this is to write acpi_osi="Linux" next to kernel boot parameters in /boot/grub/menu.lst
I added acpi_osi="Linux", but it didn't worked...
If you have any solution, or any workaround, please help me...
Thanks in advance.

When USP charging cable is connected to both the live wall charger and iphone,
the iPhone will succesfully 'Slide to Power Off'.
When the USB cable is not connected the following:
1. Hold down power button until "Slide to power off appears".
2. Slide the slider.
3. Iphone gets the spinny wheel.
4. Screen goes dark for a second.
5. Apple logo then appears and the iphone eventually turns back on.
6. No Apps are installed on this 4S.
7. Restored on iTunes several times, No change.
8. Changed USB Cable, No change.

Z77A-G43 login loop after Live update BIOS to V25.1

Hi,
Z77A-G43 windows login loop after Live update BIOS to V25.1
I'm able to see the BIOS menu. But when i continue to login to windows, it loops.
i would like to know on how to proceed on this. I tried safemode and i was able to login.
I cannot find the clear cmos jumper on this board.
Appreciate your response on this one. Thanks!
edit: I just tried removing the board battery. But still encountering the same issue.
-Paul

There is no such BIOS version for this board.
The last BIOS is v2.11 see here http://www.msi.com/product/mb/Z77A-G43.html#/?div=BIOS
As for the CMOS jumper. This must be the most stupid saving that MSI has ever done. They leave out the jumper, obviously in an effort to save costs.
Check your manual to find the location of the clear CMOS pins. Then you need to short these with a jumper from somewhere else or use a metal object to connect the pins.

Neo4 - reboots after shutdown ***Fixed***

I've had this problem since I put my comp together. When I shut down windows the computer shuts down normally, but then after a few seconds or sometimes right away, the system reboots... I have to switch off the power supply to shut it down permanently.
I've tried reversing the plugs from the power switch to the motherboard, but it doesn't help.
It is getting a bit annoying and I'm wondering if there might be some other cause that I have not thought about?

I really thought you had this checked before .
Quote from: syar2003 on 21-March-05, 17:53:15
Spontanious startups is usually caused by the PSU ( if there is not a wakeup event triggering it).
It can also be a service or driver that crash during the shutdown , forcing the system to reboot instead if automatic restart is enabled in windows,
Honor to Fredik for hitting it right on the spot .

My computer reboots after plugging my ipod into usb port

Bonjour,
Mon ipod touch a fonctionné 3 jours et depuis lorsque je le connecte avec un cordon sur un usb de mon pc, le pc reboot dès que l'application itunes le détecte. Pas de message d'erreur ni sur l'ipod touch.
Je ne perçois pas la cause de ce dysfonctionnement brutal.
Je n'ai rien changé à la configuration de mon PC !
Je vois beaucoup de messages de ce type depuis plusieurs jours sur les forum en francais.
Hello,

I see many messages of this type for several days on the French forum.

K8N Diamond reboots after shutdown :censored:?

I hope others are experiencing this too, I'd hate to be alone! Almost everytime I shutdown my PC after about 3-5 seconds it reboots by itself. Is this a known prolbem?

amt, I have a Neo4 Plat which is a different board but had a similar experience after I installed my Opty 165 but was also dealing with SATA II problems and it puzzeled my on what was going on. I had a problem with bios not recognizing the Opty which I fixed with a MurdocK modded bios and got firmware upgraded on Seagate SATA II- then end result was that it went away during this process but it is still a mystery Hope you can figure yours out. I had to hold power button down for a couple of extra seconds after it shut down or it would magicly spring back to life.

IMac running 10.9 not rebooting after network issues

This is weird, and while I am going through Apple's Knowledgebase steps - so far without success - I thought I'd post here to see if anyone else experienced a similar issue.
I was having network issues (or what I think/thought were network issues) for about a week. The symptoms looked like high packet loss, i.e. websites would simply not load reliably: sometimes not load at all, sometimes load partially. This started with some smaller websites and eventually it failed to load google and facebook. It took me some time to notice that other devices on the same WiFi did not have this issue, so yesterday I decided to reboot my iMac. Network diagnostics didn't show any issue and I was able to connect to the WiFi router just fine, just not find any websites, so I thought a reboot may fix it.
I have not been able to boot it back up since. It stalls at the grey loading screen with Apple logo and a spinning wheel for ever (I've let it sit for hours). Safe boot does not work, and starting in Verbose mode hangs at "executing fsck_hfs" and it doesn't seem to do anything else. I've booted from the install disc (actually a USB drive) and ran Disk Utility from there, but it showed not disk errors at all. It did repair a handful of permissions (I only saw iBooks related stuff and something about etc/apache2/users), apparently successfully, but it's still not booting.
Disconnecting my external Time Machine drive and unplugging the iMac from my surge protector didn't help, either. I am now creating a new image from the partition just to have an additional backup on top of my Time Machine, and I'm going to try Archive and Install next, which is the next to last step in the Knowledgebase.
I do have two partitions on the Mac (one 10.9 and the other 10.7), by the way, and booting into the older partition seemed to work right away. It's just that I don't have any use for that other partition right now, it's a leftover from back when I migrated to Mavericks.
I am baffled how all of this connects together. Network issues, boot up failure without apparent disk issues? Has anyone else seen anything like this?

I am still working on restoring my iMac with 10.9.
I've cloned the affected partition. I used Disk Utility and it Restored without apparent unto an external drive. So I tried booting from that drive, but I get the same result as booting from the partition directly. Not a major surprise I guess since this is supposed to be an identical copy.
I have also created a dmg image out of the partition, and I was able to open that on my MBP without problems! All the files seem to be there. It seems to be something specific with the, uh, boot sector or, uh, something?
Next, I booted into Single User mode and ran fsck -fy. The Knowledgebase says it's okay to do it if Safe Mode doesn't work, right? The first time it ran, I got conflicting results. It said both
** The volume appears to be OK
**THE VOLUME WAS MODIFIED**
The Knowledgebase seems to suggest that it should only say one or the other?
Running it again, it said
** The volume appears to be OK
Alas, rebooting it still doesn't work, it continues hanging at the Apple logo.

Computer reboots after every burn.

Everytime I burn a cd with iTunes the computer shuts off and reboots. It burns the cd just fine.

hmmm. this is a bit of an unusual context to be getting a BADPOOLHEADER.
lets try enlisting some additional technical help. we'll capture a minidump of the crash and send it to someone who can interpret minidumps.
To set up your machine to capture a minidump, right click on "My Computer", select "Properties", select the "Advanced" tab, select the "Startup and Recovery" Settings button, select "small memory dump" from the popup. When it crashes, look for the MiniDump file. It's usually in the folder "C:\WINDOWS\Minidump" and is called something like Mini<number>-<number>.dmp.
collect the minidump, and send it to this email address
in the email, include the URL to this thread so that the person who gets the email has some context, but also give as much information about the context of the crashing as you can.
love, b

ProBook 4430 reboots after shutdown and when power is removed.

I have a probook 4430 sitting on my desk and whenever I shut down the notebook just boots itself back up. It will power itself on when you insert the battery and also if you do get it to fully shut down and remove the power coord then it boots itself back on(with battery ofcourse). There were no hardware/software changes. I have double checked my connections to the board and everything appears in order. I changed out the power/wifi button assembly as well as the DC power jack also. Any suggestions would be much welcomed I'm banging my head against the wall here.

If you click on the Apple menu's, "About This Mac," and then click on "System Report....," it will give a battery condition report. Best guess, as stated by Kappy, is that the battery needs to be replaced.
If he bought in the summer of 2014, it should still be under warranty.

MSI P67A-G45 Issue: Computer boots seconds after Shutdown or Sleep mode

Running Windows 7 64 bit Professional
Problem: Within days of building computer in January the computer started to automatically reboot seconds after shutdown or entering sleep mode.
Attempted Fixes:
-Total re-install of Windows + BIOS
-Updated BIOS via LiveUpdate
-Rolled back to initial BIOS that came with MB
-Changed between registry option of "PowerdownAfterShutdown" between "0" and "1"
-Disabled Wake-Up Events in BIOS
-Changed to OS controlled Wake-Up events
-Changed "Restore after AC Power Loss" to off in BIOS
-Ordered a new PSU, replaced PSU
Regardless the fix, if I try to shutdown - the computer reboots within a few seconds. If I try to put it in sleep mode, it boots right back up. The only way to get the computer to shut off is by manually turning off the PSU.
I've seen that there have been frequent power-cycle issues with this particular motherboard in comments on newegg.com, just wondering if this issue has been encountered and if there is a fix available?

Quote from: Bernhard on 17-February-12, 00:10:35
Is this with no case wire connections to any of the headers? i.e. if you start it by shorting the on/off pin headers with a screwdriver tip.
Yeah, as shown here.
http://www.computer-how-to-guide.com/motherboard-troubleshooting/motherboard-post-test-how-to/
Shorted on with flathead, boots up fine. After flipping off the PSU to turn it off and then flipping the PSU back on, the dang thing waits a few seconds and boots right back up. No short required. At this point I think a ghost might be living in my computer.

MSI z77A-G43 - After Shutdown - Fans will not turn off

Just installed a new MSI Z77A-G43 Motherboard for my husband since his old motherboard died. The one thing I've noticed though is that the fans will not turn off after I do a shutdown and I'd have to do a manual shut down instead. Any ideas what could be happening? Also it will randomly restart when not shutdown completely with the fans still on.
Here are the specs of the PC.
MOBO: Z77A-G43
Processor: Intel i5 - 2500k Quad Core
Video Card: Geforce - GT 610
Ram: 8 Gigs
Hard Drive - 128gb ssd and 1.5 tb hdd
It's really barebones since I'm trying to just get it to run then get it back to normal working order with the next pay check
EDIT!!!!::
Forgot OS is Window 7 Ultimate X64

If you are sure that your CPU is seated properly and that the PWM fan connector is seated correctly, then you may want to test with another known working PSU. I am not saying that your PSU is faulty, but before exhanging the board, I would definitely test that as well.
EDIT: Just a question, did you disconnect the power switch and the other front panel connectors of your case and started the PC by shorting the Power switch [pins 6 and 8 on JFP 1]with a screw driver tip ? The remote possibility exits that the cables may have been connected incorrectly or may have a short.

MOVED: z77a-g43 cold boot overclock issue

This topic has been moved to Overclocking, Undervolting.

Hello all,
I have this weird issue with cold booting while overclocking. I've tried very hard to diagnose the problem but have been unable to find the culprit.
So I'm using an i5-2500k with the mobo in the subject. I have flashed the BIOS to the latest (2.4). So everytime I try to overclock by using a different multi (it can be as subtle has x34) the system will fail the overclock while cold booting. What I mean by that is if I do the overclock from the bios then save&reboot it will load in windows and be totally stable under IBT. I can achieve any kind of overclock up to 4.7 Ghz and it will be totally stable.
BUT, as soon as I do a shutdown of the system, upon booting (cold boot), the computer will try to boot but fail at it. I'll be prompted by the bios to reload default.
I've tried various combinaisons to no avail. I even tried to underclock the processor to sub x33. I don't understand what could be wrong. It seems as soon as I switch to anything else then auto on the ratio, it won't boot from shutdown. Weird.
Thanks in advance for your inputs.

Z77A-G43 issue with SATA drive

This is wierd
I have 4 Hitachi drives all of 1TB, perfectly working on old PC.
Today have decided to transfer them into new PC:
MB: Z77A-G43
BIOS: 1.20
CPU: Intel g2020
Primary drive is Intel SSD 120G series 330
I have attached 3 HITACHI drives successfully, they are all working fine.
but particular one forces MB to reboot before BIOS screen, last code seen on screen is A2?
Then I have decided to put dedicated controller 1st I took SilImage 3512 SATA/RAID Controller
- no changes computer reboots before post screen
After I took VIA VT6421 SATA/RAID Controller
- no changes computer reboots before post screen
searched web, found nothing useful.
any ideas what might causing this?
EDIT: tested controller SiI3512 on old PC and trouble HDD, everything works just fine :/
read AMIBIOS codes:
0xA0 IDE initialization is started
0xA1 IDE Reset
0xA2 IDE Detect
0xA3 IDE Enable
0xA4 SCSI initialization is started
0xA5 SCSI Reset
0xA6 SCSI Detect
0xA7 SCSI Enable
0xA8 Setup Verifying Password
A2 is ide ? what ide ? I give up.
it seams to me that this board is broken in several ways
- non working DVI
- faulting with valid SATA drive
what else awaits me on this road

Quote from: flobelix on 07-May-13, 04:27:27
using IDE previously and now AHCI might trouble Windows but system would none the less post. At least you should get past IDE detection but hanging at A2 means it doesn't.
I'm wondering about your statement you had been using SilImage 3512 SATA/RAID Controller and VIA VT6421 SATA/RAID Controller. Are these PCI add-on cards? Did you try all SATA ports controlled by the Z77 chipset. Are the drives used are all identical? Is the issue only happening with one particular drive or anytime you attach a fourth hdd no matter which one it is?
About the performance difference from AHCI to IDE the differences are minimal. Should be almost irrelevant for the hdds.
My discoveries:
Using sata mode IDE with windows installed in AHCI mode == windows hangs during loading (BSOD), probably missing drivers or similar.
Also I am unsure what A2 code means but I have noticed it is displayed while bios post screen shows up with the list of installed drives during normal boot.
And is also last code I see when I attach problematic drive resulting in reboot loop.
To be honest I haven't tried all SATA ports on board for sure I haven't tried SATA 1 (1st white) as there is my SSD drive.
But I have tried almost all other ports. I can try them all, but I don't think this will solve the problem.
I don't think problem is in what slot I put my drive, since same behavior is with SATA/RAID controllers.
And whit this SATA/RAID controllers this drive is working perfectly normal on other PC.
No not all drives are identical but I have exactly same drive as this one, and all drives are hitachi:
* HDT721010KLA330 working fine
* HDS721010SLA360 working fine
* HDS721010CLA332 (1) working fine
* HDS721010CLA332 (2) problematic drive == reboot loop (when its single drive or with others).
True I haven't tried to detach Intel SSD and leave problematic drive as only drive in system, I may try this tomorrow)
funny part is that HDS721010CLA332 (2) is working fine when I hot plug it.
Checked firmware version on both drives, and both drives have identical firmwares.
Only difference I know off is that working drive has 1 partition, and problematic drive has 2 partitions.
EDIT: forgot to say it passed SMART test, everything was green (hitachi sw), while hdd sentinel reported 1 bad sector but saying estimated drive working days > 900 days and degree was 98% I am guessing because of that 1 bad sector and too many working days (years) behind him.
