How to tell why my Z77A-G45 isn't booting?

Processor: Intel i5-3570K retail (new)
Mainboard: MSI Z77A-G45 (new)
Memory: 2 x Corsair 4GB XMS3 DDR3-PC1600 CMXBG3N2A1600C9 (new)
Graphics card: MSI N560GTX-Ti Twin Frozr II (new, currently disconnected)
SSD: Crucial M4 512GB (new, currently disconnected)
Power supply: Antect earthwatts 500W (used, fully functional)
HDD1: WD Velociraptor 300GB (used, rather full)
HDD2: Samsung Spinpoint F3 2tb (used, currently disconnected)
Optical drive: DH-201AS DVD-+RW (used)
Once everything is all connected up, installed in the case, etc etc, upon power up, the fans all spin up, HDDs initialize etc. Then after 10 seconds or so the system powers down again, with the screen (whether on the external or internal graphics) never having been active. There are no beeps from the PC speaker whatsoever, nor do there seem to be any indicator lights as I've had on previous MSI motherboards. The manual is completely absent of any troubleshooting section. So my main question is, is there any way to tell what stage the startup is failing on? Other threads on this forum (here and here) suggest that the problem is due to lack of processor support. As the motherboard was sold as Ivy Bridge ready, I'd like soe way of confirming this as most likely cause before paying for some fix.

Yes, the mainboard is Ivy ready, but the 'as shipped' UEFI/BIOS may not be the latest one that supports the CPU intended for installation. That has been a problem over several generations of platforms. In the past, there were green stickers with the BIOS version printed on the chips, but now, a lot of them are black chips with red dots on them, so no visual way to tell what BIOS is actually installed on the mainboard.
Only speculation, but it is very possible the UEFI/BIOS version on the mainboard does not support the CPU you have.

Application hanging after commit issued, how to tell why?

Hi All,
We're using adf bc, jsp's and jdev 10.1.2.
The scenario is this.. I have 2 views based on the same entity(called Milk). One view is the control view Milk i.e. straightforward select, no where clause. The other one is based on a join with another entity (Area), which uses where clause parameters to output a row of Milk for every entry on the Area entity. So basically for every area there is, a milk row will be output even if that row does not exist on the milk table.
So my problem was when the user edited and saved a row which didn't actually exist on the database, the program would hang. Editing of rows that do exist pose no problem at all. So then I thought maybe I should create these rows first so that they would physically exist on the database before the edit. Still to no avail..
If it's just one row created or many rows, once the commit is issued, the application hangs. I've debugged it and nothing happens once it executes the commit line, there are no error messages, it just never progresses past this line.
I've tested with the App Module tester and I can create rows here fine. Obvisouly something is wrong or it wouldn't be happening. How can I tell why it's hanging? Or can anyone suggest what I can do. It is extremely crucial that I fix this soon so I would really appreciate any help that anyone can give me.
Thanks in advance,
Liz.

Maybe you should look into
/var/log/messages.log
/var/log/daemon.log
/var/log/kernel.log
/var/log/Xorg.0.log will be overridden, afaik.

Z77A-G45 i5 3570K- Boots for a second then shuts

Basically all of the fans come on for 1/2 a second then shutoff and same thing over and over I made sure EVERYTHING is plugged in so thats not it....My understanding is that I have to update the bios? but how do I do that if I cannot get the computer running?

I actually had the same problem... I did a complete test of all my parts... but came to nothing... i dropped my rig a a friend's place and it booted without any problem...
When i got home it started doing the same thing again...
Turned out the problem was with my power outlet... though i cant understand why cos i've always been using that sam one..

How to tell my Mac that Windows can be booted?

Hey! Hello again.
I have found myself in a very stressing situation: I can`t boot windows.
Windows can't be recognized as an OS right now.
I got a windows partition using bootcamp and I was happy with it for almost a year, but recently(the last week) I installed Avast and I don't know what happened, it deleted some file that allowed windows to load and when the windows loading screen ended, it always made my Mac to restart.
So, tired of seeing which files were required to make windows start, I created another windows partition with Disk Utility (boot camp didn't allow me).
And the plan was to have all my files on the new windows and then delete the "corrupted" one. But I'm a GENIUS (sarcasm), I didn't consider that the first windows partition was "official" and made by Boot Camp, so, now, the new Windows can't even appear on the white screen when choosing OS's.
I press Alt (option) on the white screen and only Snow Leopard appears. The only way I see to solve my problem is to backup my files on an external HD and delete the partitions (except for mac, of course).
I added a picture to show the mess I created, don't flame me, I'm experimenting.

Wrong course of action.
Should have uninstalled
rollback (restore points)
boot from Windows DVD
you can't create more partitions
you could have just done a new install and reformatted the old partition
then setup backup system image for restore in the future
undo what you did and try a new direction.

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.

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

Running stock, board is otherwise very stable (memtest and prime95 passed).
About half the time, this board resets resuming from S3 sleep. I'm at a loss as to why. So far I've replaced the memory, switched PCIe slots, reflashed BIOS, set MB defaults, over/under volted CPU and Memory, and switched memory slots. In my current test, I've pulled the graphics card and am now running on the integrated GPU.
My questions are:
- if this holds, how do I determine if it's the card or the draw on the PSU (no other to test) from the card
- anything else I should try before I purchase 2x the components (as I have already done for the memory)?
Thanks!

Hi,
Please list full system spec: >>Posting Guide<<
There is no help for coil whine unless other part of the system is causing it like low quality PSU or something with GPU
i can disable c1e and cstates in biose and the whine is gone.i had a firend tell me that doing that turns speedstep off but it still on.is it bad to run with the off and why did it not turn speedstep off

Z77A-G45 has been rock solid over two years, until today

when I powered up today, everything appears to be normal. all the internal fans, drives, etc power up. all of the external equipment powered by usb powers up. Everything sounds normal. But the BIOS Splash screen never appears. I have made no changes in configuration (hardware or software) recently. This happened once about a week ago, and I did a hard reset and cold boot and everything worked fine again for a week. But today, nothing I try seems to bring me back to life.
The manual doesn't have any information about error codes, and I'm not hearing any beeps anyway (Don't think I would because there is no onboard speaker). I'm totally stumped as to how determine whatthe problem is.

okay, i guess i was in a hurry and did not provide a lot of info. to be honest, it did not seem important because as i said it has been working in exactly this configuration for a good long time, so knowing that and knowing that I can't even get the BIOS splash screen to come up should narrow down the possibilities quite a bit.

OS: Windows 7 Ultimate 64-bit
Main Problem: System Instability. I've managed to get the OS installed, and was able to eventually get VirusScan, Windows Updates, Chipset drivers, and other drivers installed. However, this was a painful process, with several BSOD's, program crashes, and other lock-ups. After doing so, the system is still unstable.
I also have an SSD I intend to use for acceleration via Intel Rapid Storage Technology (RST). I plan to eventually plug this into SATA Port 1. But I didn't get that far...
I am not OC'ing - using Standard Mode. The only change I made in the BIOS was to switch the SATA Mode to "RAID Mode". I did this prior to OS installation, per instructions. And during OS install, I loaded the Intel SATA controller, per instructions.
OS install was unusually rocky. First attempt failed. Second attempt worked, but took longer than it should have. After installation... crashing, instability, and BSODs.
Checked Memory a couple times, via Microsoft's memory checking tools. Also reseated all DIMMs, to no avail.
After some amount of troubleshooting, I saw that my memory was being reported as: F3-12800CL9-4GBXL DIMMs. I assume this is correct, and that the "Model" I bought (F3-12800CL9Q-16GBXL) just describes the whole package of 4 DIMMs. However, the one thing that is incorrect is that the timing is reported in the BIOS as 11-11-11-28. The timing specs on my RAM are 9-9-9-24. Overriding this in the BIOS to those numbers (for TCL, tRCD, tRP, tRAS) did not make any difference. Instability continued. The memory speed and voltage seems to have been set properly to 1600/1.5V.
The other thing to note here is that I just bought the MSI Z77A-G45 to replace an ASUS P8Z68 DELUXE/GEN3, which was experiencing the same (but less frequent) instability. I've been using it for a couple months, and decided to try my luck with a different motherboard. Only this one is worse. The only components that were reused were the CPU and RAM (and optical drive, PSU, and Case, if that matters), and the only other thing in common was that I had both set up in RAID Mode.
Thoughts on how I should proceed?
Thanks in advance,
-Todd

Quote from: PiranhaTodd on 28-June-12, 15:07:06
Regarding the memory speed, I'm confused. The maufacturer site (gskill.com/products.php?index=349) says:
CAS Latency 9-9-9-24-2N
Speed DDR3-1600 (PC3 12800)
Also just to confirm, to change the timing, I assume I change this in the BIOS, under DRAM Timing Mode, switch to "Link" (from "Auto"), correct? And when I do this, it enables the "Advanced DRAM Configuration" section. If I double-click that, I can specify 9-9-9-24 (for tCL-tRCD-tRP-tRAS). Former values were 11-11-11-28. I assume I leave all other fields at "Auto"? What is the "-2N" in the CAS Latency description on the GSkill site?
Here is the reason:
They are real DDR3-1600, but that means CAS = 11 @ 1.5V
Their XMP profile is buggy (in fact that's the DDR3-1333 profile).
For 1600MHz with CAS = 9, they need 1.60-1.65V

How to tell embedded jinitator applet is still running when window closed

Hello, we are trying to accomplish the same thing that is mentioned in this post from Metalink. I've searched for a solution and hope someone here can help. Instead of restating the issue I think David Wilson does a good job of explaining what is needed. Can anyone please suggest a possible solution?

How to tell embedded jinitator applet is still running when window closed
Hi,
We run an oracle 10g forms application through 9iAS over an intranet. All users are running windows 2000 professional.
We run separate frame = true but I would like to switch to separate frame = false
With separate frame = true if the user clicks the outer windows "X" close button (forms mdi window) the user is prompted to save changes before the application ends.
BUT
when using separate frame = false
If the user clicks the upper window "X" button (no longer form mdi window but regular browser window) the window and application is abruptly closed.
I'm interested in using a onbeforeunload function to confirm if the user wants to close the window. This would be placed in the basejini.htm file. This could always ask if the user wants to exit or not. If they click OK then the window closes but if they click "Cancel" you are returned to the forms application exactly where you left. something like event.returnvalue="do you really want to exit?";
However if the user exited using the normal exit form method then the applet is already closed before the onbeforeunoad event fires and there is nothing to go back to and I want the window to close automatically. This is accomplished using close.html file in post forms trigger.
So what I want and what I think many may also want is the check if the embedded applet is still running and if so prompt the user to return to the application or continue to close. Of course If the applet is no longer running then just close because there is no reason confirm closing anymore.
Does anyone have a html/JavaScript solution that can be placed in the jinitiator.htm file? or similar?
Thank you
David

Subject: Re : How to tell embedded jinitator applet is still running when window closed
Thank you for your reply and yes you did not understand my question fully.
Sorry if this is a long reply
I am able to close the browser window using information in notes 115905.1 and 201481.1, this is not the issue. We implemented this several years ago. It is workable for both separate frame = true or false.
It is most important to not allow the user to end their forms application by closing the windows browser, they must close using normal form exit commands.
What I want is to have separate frame = false, the big drawback to this option is the user can exit the application and bypass all forms code by pressing the windows "X" close button. This is why we need the code as just provided by Andrew Lenton above in this thread.
BUT Andrew's code will always prompt the user before closing the window and I do not want that. I want the user to be prompted only under scenario 2 listed below.
Here's the 2 case scenario for exiting the application.
1. If the user closes properly and uses exit form which fires all normal form triggers including post_form with it's call to close.html file.
All uncommitted changes are saved or rollback and the users session is ended normally both on the database and in the application server.
All browser windows will close, great all is good. And without Andrew's code the window will close but with Andrew's code the user will be prompted to close or not, if they select Cancel the window will remain but the applet has already ended so why prompt? ...This is what I want to avoid.
2. In the forms app. if the user clicks the windows "X" close button with uncommitted changes. The browser just closes the changes are rollback without prompting the user to save. The users sessions are now lost and still running in the database and application server until they are timed out.
If I use Andrew's code then the user will be prompted to continue to close or go back, if they click Cancel to go back then focus returns to the forms application and the user can continue to work. If the user clicks OK then the window closes and unfortunately their sessions are still lost until timed out.
So what I desire is to add to Andrew's code to check if the embedded applet is still running and prompt the user to close or not accordingly.
Something like:
Basejini.htm like
</HEAD>
<SCRIPT LANGUAGE="JavaScript">
function maximizeWindow()
window.moveTo(0,0);
window.resizeTo(screen.availWidth,screen.availHeight);
function confirm(){
If(document.embeddedapplet.closed())
Win.opener = self;
win.close();
Else if
event.returnValue = "Closing Forms Application. OK to continue?";
</SCRIPT>
<BODY %HTMLbodyAttrs%, onload="maximizeWindow()", onbeforeunload="confirm()">
%HTMLbeforeForm%
I hope this explains my requirements.

I'm sorry this is not helpful at all.
Note 199928.1 is only an alert which does not stop the closing of the window and still displays as an alert if the user does close properly using exit form ... so why would you want to display the alert then?

Closing thread.
Thanks,

Hello,
I had the same issue last year - wanting to provide a warning on closing the browser, but only if the Forms session is still running. The approach I took is described below, see also the thread where I originally posted this at Closing brower window
Hi there,I've had a similar requirement - or rather, the two conflicting requirements: to warn when the browser is being closed, but for the app to be able to close the browser without a warning being fired.
To always provide a warning when someone (the user or the Forms app) tries to go to a different page (e.g. your close.htm), use Javascript like:
function confirmExit(){
if(appletRunning==true) {
msg="Closing this window or navigating to another page will end your SomeGreatApp session.";
window.event.returnValue=msg;
And make a call to confirmExit() in the onBeforeUnload event of your main page.
You'll notice I first check an 'appletRunning' variable before displaying the warning. This Javascript variable is set to true by my app when it starts up, using an embedded Javabean that calls out to Javascript. Once that variable is set to true, then the warning will be displayed if the user tries to shut the browser by clicking on the 'x' button, or to go to a different URL.
When my app is shutting down, it uses the same Javabean to set appletRunning back to false. It then navigates to a close.htm - which will be done without a warning being displayed.
See Re: How can a Javabean call Javascript function of the basejpi.html?? for example code on how to call Javascript from a bean embedded in your Forms app.
Hope these ideas help you out, it's worked for me (so far, anyway!!)

How to tell if Im on AT&T?

Hey guys. I guess I live right on the edge of an area covered/not covered by at&t. I have noticed that my reception bars have changed from black and white to colored and I have even seen a E next to it. So my question is how do I make sense of the different colors or letters so I know if Im on AT&T or some other network?

how to tell if Im actually using at&T's own cell towers or a competitors.
You will never be using a competitor's towers. A competitor would be T-Mobile, Sprint, Verizon, etc. and you'll never connect to their networks. You may in some cases be using an AT&T partner. In this thread, one poster advised:
"To get an indicator when you are roaming on an AT&T partner network, call 611 and ask them to activate the (free) "Off Network Alpha Tag" on your account. If they ask why, tell them you want to be a good guy and observe the (usually unenforced) data limits while roaming."
Hope that helps.

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
Bios Version: 2.10
Graphics card: Club3D GeForce GTX 550ti 2GB
PSU: Corsair TX 950W - 100-240V ~ 12A 50/60Hz
CPU: Intel Core i7 3770K / 3.5 GHz Processor (Stock boxed fan)
RAM: Corsair Vengeance - 32 GB (4 x 8 GB) - DIMM 240-pin - DDR3 - 1600 MHz ( PC3-12800 )
HDD: OCZ-Vertex2 128GB SSD (OS)
Hitachi HDS722020ALA330 2TB HDD (Media/Backup)
Samsung 840 Series 500GB SSD (Media/Backup)
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...

How to tell AE CS6 to use bundled Mocha rather than Pro?

I recently upgraded my bundled Mocha from AE CS6 to Mocha Pro 4, but for some unknown reason, it won't let me export shape data in Mocha. There seems to be no data at all, as even trying to paste in Notepad results in nothing. Tracking data, however, works fine (both in AE and Notepad).
Since I cannot figure out any solution in Mocha, the only thing I can do is use bundled Mocha rather than Pro... but I do not know how to tell AE to use bundled Mocha rather than Pro when I click 'Track In Mocha' (...a setting which was changed when Pro was installed).
Does anyone know where/how I can switch it to Mocha bundled when you click on Track In Mocha? (or, does anyone have any idea why Pro would not export shape data, whereas the same project in bundled Mocha did?)
If anyone has any answers or theories, please let me know ASAP, as I have a project I'm trying to complete, and (as luck always has it) the weekend is now upon us, and support is closed over the weekend.

I tried connecting MBP and TC via Ethernet - after verifying the settings that you suggested - and it does not work: if I turn Airport off, Time Machine says it can't find the TC
Any other sugestions?
Ok, then ethernet is not getting an ip address from the TC and is plugged in wrongly..
You still didn't give me any idea of what actual model the linksys is.. and why is it in the network.. Is it a modem router?? If you have cable internet just throw it away and use the TC.
If you have the linksys as modem, then bridge it.. turn off wireless and run pppoe client on the TC.
If the ISP does not allow pppoe client mode then simply use the TC in bridge. Turn off all wireless in the linksys and just use the TC.
Still need info on how everything is setup to analyse the problem.
