Hp dv6t won't go past blue screen blinking cursor

Hello,
  Please help me figure this out!  I have looked at the boards for days and weeks but cannot solve my problem.  No matter what i have tried so far, I cannot get past the blue screen with blinking cursor.  A couple months ago I was out of town and blue screen came up i was able to hit F4 rapidly and eventually get it to work several different times that trip.  Now however, I cannot get anything but blue screen and blinking cursor.  Thanks in advance for any help!  Heidi

Hi @heididmn1800000,
Welcome to the HP Support Forums! 
I am sorry to hear that you cannot get passed a blue screen on your HP dv6t PC. I will try my best to help you with this. To better guide you, could you please tell me the full model or product number of your computer and the operating system that is running on it. Here are some guides for How Do I Find My Model Number or Product Number? and Which Windows operating system am I running?.
In the meantime, here is a document for Troubleshooting Error Messages on a Blue Screen that may Occur During Startup or Boot, that may have a solution for you.
I hope this helps, please let me know how it goes.
Thank you and have a great day!

  • Mid 2010 MacBook Pro won't boot past blue screen

    I've been having problems booting up my MacBook. I can't get past the blue screen. It went from booting slow at the grey apple logo screen to not booting up at all. Is it a problem with my hard drive? I also have boot camp running as well, but I can still see the boot camp drive for windows and my OS X drive, as well as my installation disk when I have it inserted when I hold the option key at start up.
    I'm still able to run windows on it without any problems when I pick the windows drive. I tried different methods from different forums but I'm just not getting through. I tried holding 'c' to boot up from cd and I let it run over night but it never got past the grey apple screen with the gradient wheel (still spinning). I had already used time machine to back everything up before this happened since I was able to boot up properly (but slowly). Can anyone help? It's driving me nuts, and I can't remember what os/firmware version I'm running.

    n your signature you said you are running 10.6.3.  So let’s assume you are running Snow Leopard.
    It sounds like your diagnosis of disk problems is correct.  The OS X partition may be corrupt.
    Try booting in Safe Mode.
    http://support.apple.com/kb/HT1564
    Try again to boot in normal mode.
    If it will boot in Safe Mode but not in normal mode then you could have some 3rd-party software preventing the boot or you could have a corrupt disk or OS.
    Boot as from the startup manager (Boot - option) and then select the installation disk.
    Hopefully that will work better than starting with the Boot-C option.
    Then try to repair the system disk.
    Start the Disk Utility.
    Perform the steps in http://support.apple.com/kb/PH5836.
    If it repairs OK but still won’t boot reinstall OS X.

  • PowerBook G4 won't boot past blue screen

    I've read a couple of posts with similar problems. The jist is, I did a security update/restart earlier and now my laptop won't boot past the blue screen after the white screen with the gray apple. I think I'm on Mac OS 10.4.11 but I had it on auto-update so that could be incorrect.
    I've booted from the install disk and run a diagnostic from the First Aid bit in the Disk Utility. It says that there are no errors found and the S.M.A.R.T. status says "verified" as well. It won't let me boot into Safe Mode (although, I could be doing that wrong as I'm not exactly clear on how to do it - pressing S doesn't seem to do anything, but if I press Command + S it takes me to a text listy thing and I've run the "fsck -f" system check (which seems like the same as the disk utility check?) from there and also gotten the "volume is ok" message. There was also a suggestion to run some kind of diagnostic after booting with the D key from the install disk, but I was never able to get the disk to boot from the D key, only the C key.
    I'm sure that this is kind of the "same song, different verse," kind of post, but I've not read about volumes registering as okay. I'm a little wary of a archive-and-reinstall as I've not ever done that before (so, if that's the suggestion you have, I would really appreciate loads of specifics on how that works so I don't mess up!)
    I've read in several instances suspicion of a hard drive problem but I've not had any slow downs or any crashing. I did travel to the UK for about 10 days, but I didn't even change the time zone on my laptop while there, so I don't think that's it (but I suppose it could be.)
    Lastly, I did recently replace my keyboard. A few keys had become non-responsive so I replaced it and have had the new keyboard for a bit over a month.
    Suggestions? Ideas? Sorry if it's a repeat post -- just felt like the circumstance was a teensy bit different. And also, thanks very much for any info you can give.

    Linsey:
    If you can boot your computer into Firewire Target Disk Mode and you have access to a second Mac that supports firewire, you may be able to back up items that have not been backed up previously.
    If you are able to back everything up successfully, and you have tested your backup to be sure it is sound, then we can proceed with re-installation of the OS. The best option is to completely reformat and erase the HDD and then install the OS from disk. (I will post complete step by step directions). This will enable you to start with a clean slate/HDD. Your other option would be to use the Archive and Install option. Think it over and let me know how you want to proceed.

  • MAC DUO won't go past BLUE SCREEN on start-up.

    Please help!
    My mac duo has crashed after a mac software update. Now it won't logon past the blue screen!
    I've tried everything online like DISK UTILITY on Mac os x disc and SAFE MODE but no joy whatsoever.
    SAFE MODE won't work now after doing it three times. Is this typical?
    Should I re-install the MAC OS X using the option to copy existing files and applications?
    Any help would be greatly appreciated.

    There are two major problems out there right now. That is also part of the problem. We are not used to two problems in our domain.
    I own 20 Mac's in my office, and I only did the latest updates on my MacBook Pro 17-inch portable and my G5 Dual 2.3 GHz desktop that has two 30-inch Cinema Displays. Both machines had the Adobe CS 2 Professional Suite with Acrobat Professional.
    I had both of the prevailing update problems on my MacBook Pro—1) unable to restart and 2) Acrobat crashing the system.
    On the G5, I only had the 1) unable to restart problem.
    I won't update the other machines until these problems are resolved by the OEMs.
    1) Unable to Restart. Of the two major hiccups out there, the link below indicates Quicktime's update is the source of the 1) unable to restart problem, fixed by deleting startup items, I believe. Again, I had this 1) unable to restart problem on both operating systems (PPC and Intel versions). Recovery of the 1) unable to restart problem is done in in Safe Mode by holding down the Shift key when restarting. This may take a long time to reboot, so keep holding down the shift key until the grey screen and startup wheel is seen. Then delete all startup items and Adobe Version Cue if you have it. (Use Version Cue Uninstaller.)
    http://www.macworld.com/news/2006/05/24/cs2quicktime/index.php
    2) Acrobat Crashing the System. Acrobat's freezing the entire OS 10.4.6 system is a result of the Security Update 2006-003, fixed by rolling back to a pre-Security Update state using Archive & Install for re-installation of the OS. Archive & Install does not erase your files or network settings. Printers may need to be re-added.
    Apple has released two products (QT 7.1 and SU 2006-003) that fouled these systems. Bad Quality Assurance, I think. I am not sure if the Security Update problem is an Apple or an Adobe software problem, i.e., Adobe may have not followed some software guidance from Apple in Acrobat 7.07 or earlier versions. I am certain both companies are aware of the problem, but I am uncertain of the fix for Acrobat. We probably do need to update for security, but I can't live without Acrobat. So I will wait it out sans Security Update 2006-003.

  • Old iMac was sluggish and now won't go past blue screen.

    We have a pretty old iMac, it will be 7 years old next month. I totally expect for it to slow down and have issues being that old, but was hoping I could maybe get a few more years out of it for my in-laws. We gave it to them 2 years ago and now it's going downhill. It has been sluggish for quite awhile and now will not turn on past the blue screen. No spinning wheel, just a blue screen and an arrow.
    Is there anything we can do? Could we perhaps completely wipe the computer as there is nothing important saved on there? Would that even help? We are probably at the end of it's life here, but just thought I'd come for suggestions first.

    I suspec the machine has had a hardware failure. If you can run Apple's Hardware Test, you will need the original install discs that shipped with the computer to do this. Run the test in Extended Mode at least 2-3 times back to back. The reason to run it multiple times is AHT is not 100% reliable however if it detects an error the error is correct. If you get an error that means a trip to the local Apple Store or AASP for repair, based on the vintage of the machine I woudl recommend an AASP. If you are aware of AHT then please click Apple's instructions located at:
    Using Apple Hardware Test
    Good luck!

  • 14" iBook won't boot past Blue Screen?

    Hi,
    I have in my possession my Sisters 14" iBook G4. It boots with the grey Apple logo but then freezes at the blue screen. I'm guessing it's either the hard drive or logic board, does anyone have a procedure to follow to diagnose the fault? I don't have the original discs but do have a 10.5 retail box.
    Thanks in advance.

    Spudnuty - I think you might want to hear this...
    I just bought an ibook G4 1.2Ghz "Late 2004" model off of ebay, had the blue screen problem. I bought it because I thought it might have been the OS (freeze at login) and the previous owner didn't know, but it was an actual freeze... actually froze a few times while at the spinning wheel at startup, and would randomly display a dark blue screen sometimes at startup.
    I am an ACMT, I decided to disassemble the machine as per the service manual and get it down to basically the logic board, even pulled off the top display entirely. Ran an external monitor via mini-VGA, external HD via Firewire... still froze at blue screen. So I decided something similar to your suggestion - I pulled off the heat sink, only to discover that the conventional way of cooling a cpu/gpu (heating compound directly under heat sink) had been abandoned on this model for some crappy adhesive pads. The pads had a bit of thickness to them, so I decided to cut of a small section of the top shield, fold it into a nice square and flatten it. I then put some heat sink compound on both the cpu and gpu, put the metal "shim" on the gpu and tightened down the heat sink. Guess what? Started up in a jiffy. I put a fresh install of Tiger on it, have been playing multiple Quicktime vids looped for a while now... machine is going strong.
    All that to say, shimming works on these later ibook G4 models that get the blue screen, I've confirmed it. Just remove the adhesive pads, shim with something heat conductive (maybe even aluminum foil!), add heat compound and run it for a while.

  • My iMac won't boot past grey screen and it didn't come with a os x disk

    My iMac won't boot past grey screen with apple. I've tried booting in safemode but that didn't help and my iMac didn't come with a os x disk.

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 10
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 11
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 12
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • IMac won't get past startup screen, no matter what. Pls help?

    I just inherited a mid-2010 iMac from a friend. It hadn't been used for months, and now when it is started up, it won't get past startup screen. It shows the 'slot' looking image on the bottom of the white loadup screen, then it's just the apple symbol and the whirly thing going around forever. I've had it going for over half an hour at one point, and nothing changes. I have tried all the different reboot key combos, such as C with a startup disk in it, D for hardware test, command S for safe mode, etc. The only thing which makes any difference at all is using the T key at startup, when I do get the three-pronged white symbol floating around screen.
    It is a 21 inch with 500gig, and I believe it's running Snow Leopard. They never had a problem with it before, but now after the months of disuse, it is doing this. Please, can anyone help? Thanks!

    I'm not sure if a dead PRAM battery would give you these symptoms, but one possibility is that if the computer was off wall power for months, the PRAM battery, a small coin cell battery that controls certain functions, may be drained and  dead.
    But, in any case, try an SMC Reset. You must follow the timing for this exactly.
    http://support.apple.com/kb/ht3964
    And then a PRAM Reset.
    Hold down Option-Cmd-P-R together at the startup chime, listen for two more chimes, total three, then release all the keys to finish booting.
    You might also try a Safe Boot by holding down Shift at the startup chime. (Cmd-S isn't for Safe Boot, it's single user mode.) Give it much longer to boot than usual, but if it doesn't finish in perhaps 5 or 10 minutes, then you'll have to give up on that.

  • Won't get past "Platinum screen", keyboard not recognized

    Hi all,
    I just built a system, haven't even loaded up the OS yet. On the first boot, the computer won't get past the screen which says "Platinum" and says "tab to switch to post" or "del to run BIOS setup." The lights don't flash on the PS/2 keyboard i hooked up (a 6 year old Compaq one). I then tried a 2-year old Dell PS/2 keyboard with the same result. Is this problem fixable? I bought this off of Newegg and there is still time to return it, if I need to. Thanks for your help in advance. Also, if this topic has been beaten to death, I'm sorry. I'm in a state of panic right now since this computer isn't even for me.

    I had the same symptoms first time I tried to boot my then-new K8N Neo2 Plat.  I had the advantage of having the D-bracket, which was telling me it was hanging in the memory test.  I had stuck in some cheapo memory to set up the board, waiting for my good stuff to show up.  Turns out the memory was not up to the task.  When I stuck in the good stuff, she fired right up.  What memory are you using?  Are you sure you don't have the D-bracket?  it looks like a PCI back-plane USB bracket, except it has 4 LEDs on it (in addition to 2 USB ports and a 1394 port).

  • NAND script and won't load past apple screen

    My I phone 5 has crashed won't load past apple screen and has a list of NAND scripts can anyone help or had this happen

    Standard troubleshooting...
    1. Remove apps from the Recently Used (multi-tasking) list...
    - From any Home Screen, double tap the home button to bring up the Recents List
    - Swipe up on the app preview card to remove it from the list
    - Press the home button when done.
    2. Restart by pressing the sleep/lock button until you see the slider.  Slide to power off.  Restart by pressing the sleep/lock button until you see the Apple logo.
    3. Reset by pressing the home and sleep buttons until you see the Apple logo. Takes about 5-15 secs of button holding and you won't lose any data or settings.
    4. Restore with your backup.
    5. Restore as new, i.e. without your backup. See how it runs with nothing synced to it.    You may need to try DFU mode (Google for it).
    6. If still a problem, it's likely a hardware issue.
