Z68A-G45 (B3) Won't boot properly! Help!

Today I used the computer but had to go out for a while. When I came back, the pc was still running but none of the peripherals were with power! I tried to reboot, same thing. No video was detected by the monitor and after checking for a while, I realized that only one led was on at the mother board (of a total of four). I tried unplugging everything and still only one led turned on. all the coolers works, but the DVD reader don't and the led at my GPU indicates power... I don't know what else to do. Help, please! x-x'
***Update***
If I connect everything, it flickers a little. The Led of the card reader seems to be having a hard time tuning on, it flickers a lot like it isn't getting enough energy. Does it means I a have a Power Supply issue? Also, it won't make any bip.

Thanks for the replies but I figured it out myself. I had made a recovery cd and I just reset to my latest backup from that

Mac won't boot properly unless in safe mode

Recently I updated my MacBook Pro to OS X Yosemite. I then started the process of the data encryption.
I don't know what happened, but maybe the encryption failed, because now every time I turn my mac on, it won't boot properly unless it's in safe mode.
Either it will have a black screen with a visible cursor, or just the desktop with no dock or the bar along the top and no icons, or it does boot up properly, but works extremely slowly. Like if I was to press the apple symbol on the top-right of the screen, it would take 5 minutes to actually open it. Nothing works properly.
And so I opened up my system preferences, and discovered that the Encryption is stuck on half-finished. But I can't stop it. If I try to turn encryption off it says I have to wait till it's finished. But it never does, the progress bar never moves.
If I open System Preferences while in Safe Mode, the progress bar for Encryption is grey, and underneath it says "connect to power to continue encryption". But it IS connected to power.
Have I stuffed my Mac? Is there a way to get it working again?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

My Sleek won't boot properly! Stuck on Recovery/Rescue m

Each time I boot my Zen Sleek it either goes to the rescue mode or it just locks up on the Creative logo. I've had it for a few months and this is the first time it seriously locked up on me. I hard reset it on the bottom and it's still the same. I tried to run Disk Cleanup through the rescue mode and it doesn't even run it!! I don't know what's going on... Yesterday it was playing like a beauty.

Bootcamp Windows Installer won't boot properly on rBMP late 2013

I have been redirected to this community. I will repost the same question I asked in the mackbook pro community. I am new to Apple Support Communities, I hope this is okay for me to ask the question here again.
Here is my post in the other community: https://discussions.apple.com/thread/5922375?tstart=0
I just bought my MBP Retina 13" Late 2013 last week. It came with Mavericks 10.9, and I have since updated it to 10.9.1.
I have installed Windows 7 64bit using Bootcamp, and ran into a situation, which I hope the experts here could give me a hand.
I used the first two options in Boot Camp Assistant (BCA) and sucessfully created a Bootcamp Windows Installer for Windows 7 64bit on a USB Thumb Drive (USB 3.0). Then I launched Boot Camp Assistant again, and selected the last option to install Windows 7 64 bit on the bootcamp partition, the installation went through successfully. Both Windows 7 and the bootcamp drivers are installed, and I am able to dual boot OS X and Windows properly.
However, if I try to launch Bootcamp Windows 7 USB Installer created using BCA as described in the above by holding down <option> key while rebooting, and select the USB device lableled as 'Windows', Windows 7 Installer starts (in BIOS boot mode, I believe) and then it freezes after it gets to the language selection screen, the mackbook no longer responds to either the trackpad or the keyboard.
In other words, this Windows 7 USB Installer boots properly when launched by BCA's third option. However, this USB Installer does not boot properly when launched by selecting 'Windows' after holding down <option> key while rebooting. What am I doing wrong here?
Any help will be greatly appreciated!
Thanks,
Joe

I did create a Recovery Disk from inside Windows 7 this weekend following your suggestion. Unfortunately, this has the same problem as the installer.
However, USB Installer I created for Windows 8.1 could boot properly both in BIOS boot mode or EFI boot mode. This Windows 8.1 USB Installer is created using the standard procedure for the BCA; the only difference from the Windows 7 USB Installer is that I used Windows 8.1 ISO instead of Windows 7 ISO.
With this Windows 8.1 USB Installer, I am able to access the BOOTCAMP partition and perform necessary operations to fix startup issues, and perform backup and restore using the native Windows tools for the BOOTCAMP partition. And no need to spend $30 on WinClone
Thanks for your help!

Mac won't boot up, help required!

My mac came up with a message saying to power the mac down and re-boot it. I powered it down and now it won't boot back up again, just going to a blue screen with the curcular lines icon spinning round and nothing happens. It wont boot up in safe mode either and can't get it to recognise the OSX cd to re-install they system software. Have tried booting up with CD in and holding down C but nothing is happening.
Any help would be greatly appreciated
ps. I'm running OSX 10.4

Hi ressull, and a warm welcome to the forums!
You don't mention which Mac. We need to know.
Do you have Firmware Password Protection on? That disables any Boot Option keys.

Toshiba A350 sometimes won't boot properly

I notice there are number of problems similar to this but no one has a fix.
Problem:
1) *Sometimes* when I boot my laptop the power light comes on but the screen stays black. Doesn't go any further.
2) *Sometimes* when I boot my laptop it boots to the Windows start up screen but with thin rainbow coloured lines on the screen (occasionally you can make out the background Windows start up screen). Doesn't go any further.
3) Most of the time it boots and it works perfectly. No crashes or screen problems.
After holding the power button down for a few seconds during 1) and 2) to "shut down" after a few attempts booting it will boot properly.
So far I've flashed the BIOS to the latest version and changed Processor Power Management to 100% under power options (advice from a link on Google). Neither have helped.
Any ideas on this problem? It seems quite specific to start up as it works well otherwise. Very annoying having to try multiple times to boot.
Specifications:
Toshiba A350 (approx. 1 year old, out of warranty)
Windows 7 Pro x64 (upgrade from Vista)
Intel Core 2 Duo P7450 2.13Ghz
4GB DDR2
ATI Mobility Radeon HD 3650 (512MB discrete video memory)
Thanks.

I have exactly the same problem
(Problem:
*Sometimes* when I boot my laptop the power light comes on but the screen stays black. Doesn't go any further.)
My laptop only doesn't start on battery only. The power light comes on and the stays on with the laptop in a freeze (nothing displayed on screen). The only way to get this light off is to remove battery.
Starts EVERY time with the AC power connected (with or without battery).
Works perfectly normal once booted
SOMETIMES starts with the battery only if I boot soon after I have already been using the laptop
I have tried the static release processes but doesn't work.
After having this trouble I updated to latest BIOS but has not helped
Tried a different battery and has not helped
Is a Toshiba Satellite PRO L500 T4400 4GB 15" Win7 Laptop - only 3 weeks or so old
Very annoying!
Please someone with an answer??

Dropped iBook - won't boot up, help!

Because I'm an idiot, I dropped my beloved G4 iBook on the ground and now it won't boot up. I can get it to turn on, I get the startup chime, it gets to the blue screen with the grey Apple and spinning progress indicator...and that's it. The spinning disc just keeps on spinning indefinitely. No error messages, no kernel panic, nothing like that. Tried booting in Safe Mode...get the blue screen with grey apple, no spinning disc, and that's as far as I can get.
I bought it secondhand from a friend so no warranty or Applecare or anything like that. Is the hard drive okay? Could something have come loose and just needs to be snapped back into place? Did the motherboard get cracked? What could cause this type of problem, especially since I can't even get it to boot in Safe Mode, and what can I do to fix it? Is it even fixable? Have I lost all my files? Can I just take it to a repair shop and everything will be okay?!?!
helllllllp!!!! :'(

Hi from another idiot iMac user (I last posted when I spilled a glass of water on my desktop's keyboard...)
I dropped my iBook G4 on the stairs this morning Since it sort of slid down the carpeting I thought I'd be OK but it was just like the other used described - Apple logo, spinning startup icon, a few clicks and whirrs then nothing.
I followed your instructions below, and the Installer loaded. I have clicked on Introduction, agreed with the licensing, selected a destination (clicked on HD), but then I got a message "You cannot install Mac OS X on this volume without changing your install settings. Click Options to change settings. A newer version of Mac OS is installed."
I never got a Repair Disk button. I never installed newer software, unless it was an update that downloaded from Apple. What should I do?
Thanks!!!!

MSI GT70 ONC-008US - Won't boot properly

For whatever reason, my laptop refuses to boot properly now. For awhile it just had a problem booting from sleep (no image on screen, seemingly working otherwise), so I avoided doing that. It also did this when trying to power on the laptop, but this problem was fixed ignored by simply holding the button and trying again.
It now it wont boot, despite the number of times I might try to make it. Nothing appears on the screen at all, sometimes my keyboard back-lights come on but now not even that happens. I don't know what to do. The hard drive (I think it's the hard drive?) makes a sort of clanking sounds a couple times and then goes quiet, occasionally making small beaps. USB devices power up per usual.
If you know what might be happening I'd be eternally grateful. My only guess is that the hard drive is failing, but wouldn't the screen still show something if it was simply the hard drive failing?
##UPDATE:## After trying a million times it finally booted. I still want to figure out what is going on. Please help

Quote from: tdesantiago on 07-April-13, 07:15:15
I've contacted at least three computer repair shops in my local area and all seem to think it's the motherboard. FML
It sucks. But it should still be under warranty from MSI. I would contact them to be perfectly honest.

G5 won't boot properly/running incredibly slow :(

Hey, friends.
So my mom and dad were kind enough to gift me their old G5 (I think they got it in 2006). Trouble is, I can't get it to boot properly. It takes about an hour for it to go from turning on to the point where the contents of the desktop appear and I would (theoretically) be able to do something. After just sitting there for the longest time with the color wheel spinning, the screen went blank although the computer and monitor were still on. Eventually it came back, but the computer runs incredibly slow. Like, clicking on the Apple menu caused the color wheel to spin for about ten minutes.
I tried /sbin/fsck -fy, which is about the extent of my computer doctoring skills and this is the message I got:
diskOs9: I/O error.
Invalid node structure
(4, 1771)
** Volume check failed.
Any thoughts?
Message was edited by: Alex_C.

Pull the drive and put in a new one.
I've never had much faith if any in Apple fsck or First Aid.
The G5 stopped being sold in 2006 so that would make it one of the dual-core / pci express graphics.
See if you have 10.4.6 or later DVD so you can attempt to repair and install while you wait to get Alsoft Disk Warrior, and a new system drive to work with and build a new boot drive etc to which you can copy over any files & programs you need.
An emergency boot volume is pretty much a necessity with Mac. Your system drive directory structure is not going to make it. In theory a Safe Boot can deal with minor corruption and rebuild boot cache.
There are some FAQs to guide you in your doctoring and sharpen your skills!

Macbook won't boot properly.

Macbook won't boot. When turned on, it starts clicking; after a while, I get a gray screen with a blinking folder in the middle that has a question mark on it. After a minute or two, it shuts off.

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
Or if you are running 10.7 Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 partition.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

Computer won't boot properly

So with my pc, I have been having a problem where whenever I boot it up I will get the black screen of death.
Basically after I start it up, instead of the login screen I get a blank black screen with just a curser. I still hear the Windows chime.
However I can still boot into safe mode. I have determined that it is a graphic card problem because whenever I uninstall the drivers, it works just fine. No matter what drivers I use, it still won't work. I have a gtx 970. it works fine with Intel hd graphics 4600. Also if I wait 1 minute between each attempt it sometimes boots up after around 5 attempts.
I tried re-installing my os but that didn't work.
I found some fixes where you do control alt delete and open the task manager and restart explorer.exe but that did not work either.
Any more suggestions?
Thank in advance.

I have followed the format. I hope this helps a little...
Hi all, so I am having a problem with my newly built gaming desktop. Whenever I boot it up, instead of showing the login screen it shows a black screen with a cursor. Whenever I login, (I can still type in my password) I see a blank desktop with just my background. Also if I keep it idol for long periods my explorer.exe will stop working and my desktop will disappear and just show my background.
Sometimes after about 5 attempts to boot it will succeed and boot normally. (If I wait about a minute between each attempt)
These are the things I have tried:
1. changing video card drivers
2. attempting to restart explorer.exe (unable to access task manager)
3. re-installing Windows
4. using integrated graphics (worked just fine)
How I isolated the problem: I am still able to access safemode. I disabled my video card driver and my computer now works just fine. Whenever I enable it my problem continues. Also when it will boot up everything runs perfectly. My games run just as they should.

Mac Mini Core 2 Duo died and now won't boot - any help or advice appreciated...

Hi, all
I have a core 2 duo Mac Mini (possibly a 2008 model?) which has been retro-fitted with a superdrive at some point in its life and was running Lion.
It used to be left running 24/7, but one day I returned to find it powered down and it will not boot up at all now. Applying power and then pressing the power button results in the cpu fan starting, and the HD spinning up - the white power indicator lights steady, but other than that there is no sign of life - no noises, beeps, no display, nothing.
I'm not averse to getting the lid off (I've opened up a fair few mini's before ) so any suggestions as to what my next step should be?
As an aside, the Intel minis have a small push button on the logic board, about half-way down the right hand side - what is this for?
Many thanks in advance for any help and advice you may be able to offer.

Thanks for your reply, mooblie...
I have tried the SMC reset (which, unless I have misunderstood occurs as a result of removing all power for a while then reconnecting the psu and turning on as normal after a few seconds delay) with no luck.
The PRAM reset is a bit of a problem, though, as I do not appear to have any keyboard function - I'm using an aluminium Apple keyboard and mighty mouse (both are the wired variety, plugged into separate USB ports), but the 'boot' process doesn't appear to get far enough to enable operationof the keyboard (shift lock light doesn't light if appropriate key pressed), so I can't give it the 4-finger death grip at power up. The mouse illuminates, and I've tried all 4 USB ports, BTW...
I forgot to add to the previous post that there is 2GB RAM fitted, and both Bluetooth and Airport.

Macbook Pro won't boot! Help me!

Macbook Pro 15 inch mid 2010 - 4gb - 500gb - running OS X Yosemite
Okay. I've tried resetting the NVRAM multiple times. I've also reset the SMC several times as well.
I was using my Macbook Pro like usual when all of a sudden it shut down. After that, I've been unable to successfully boot the machine. Sometimes it will try but will never actually make it to the desktop. Even when I boot using the ALT/Option key, it will sit on that screen for several minutes sometimes and then shut off again, usually just the screen goes black. And no, I can't see any data when I shine a light on the screen.
The furthest I've got is to disk utility where I was able to "unlock" my hard drive and begin a repair. It shut down before the repair could complete.
What is this? An HDD problem or something worse? Thanks for any help!

If you have the original installation disks, use that to try to access and repair the HDD.
Start the MBP as if you were installing the Snow Leopard OSX.
When you see a menu bat appear at the top of the display, click on UTILITIES.
From the drop down menu, select Disk Utility.
Run Disk Utility>First Aid, Verify and Repair.
If the disk cannot be repaired, it will have to be replaced.
Ciao.

Won't boot up, help...

My two and a half year old reliable laptop recently became unstable and started freezing up. I then noticed issues of it becoming slower to boot up and very slow to process iPhoto or iTune commands. Lastly, the dreaded white screen with the folder and a question mark at startup. I followed the instructions for booting up by resetting the SMC and the NVRAM settings. This seemed to help since I was then able to boot up successfully. Today however I planned to boot up in safe mode and I am unable to boot up at all. I got the apple logo, the progress indicator and the blue bar that ran all the way thru the full bar at the bottom of the screen and then disappeared. The apple logo and progress indicator remained spinning for over an hour so I shut it down. I understood it takes longer in safe mode but I thought that was excessive. I attempted safe mode again and the screen gets as far as a third into the blue bar and then the screen goes black. I am not able to boot up at all. I don't know what to do, is my data on the hard drive retrievable?

hi AdreesInator,
Welcome to Lenovo Community Forums!
Try Performing a Power drain and see.
Remove the AC and Battery
Hold the Power Button down for at least 15sec
Reconnect just the AC and check
If not:
Try Booting into Safemode and check if the HDD is present.
Start Hitting F2 when you power on the system
Under Information Start look for this
IF the HDD is not there then I think you have problem with the Harddrive.
You can try reseating it or try calling Lenovo Technical Support Team.
Let me know our findings
Hope this helps
Cheers!

Mac won't boot properly after putting in Windows 7 boot disc

I wanted to get Windows 7 on my Mac, so I got the disc, ran boot camp assistant, and when it said install Windows 7, I put the disc in, and clicked continue. The Mac reset, and after it got past the white screen, it went black, and my keyboard and mouse stopped working. Now I can't take the disc out because it won't let me go to my desktop.

      left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in
      your Utilities folder. At the prompt enter or paste the following:
        /usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
