• HP Pavilion Elite e9220y PC, black screen with blinking underscore.

  Hello. I have a HP Pavilion Elite e9220y with Windows 7. I have a black screen with a flashing underscore.

  I stood and went to the bathroom and came back to this (on fiance mobile atm). If I go, I can do ctrl + alt + delete and get everything except the system recovery... so I made a recovery CD.

  In the recovery CD, I get the options to
  Startup Repair
  System restore
  System Image recovery

  Windows Memory Diagnostic
  Command prompt.

  I have everything but my mouse, screen and keyboard connected. No CD in except for the recovery CD.

  Startup Repair found nothing, so I tried to restore the system... He said it restored to an earlier date, but I get the same screen and the same options... So I tried the following steps:

  Boot from the new rescue CD, select repair your computer and choose the command line. When this charge, enter the following commands and press on enter after everyone – including spaces as shown.

  Bootrec.exe

  bcdedit/export C:\BCD_Backup

  c:

  Boot CD

  BCD attrib s h - r

  Ren c:\boot\bcd BCD.old

  Bootrec /RebuildBcd

  Bootrec /fixmbr

  Bootrec /fixboot

  Remove the rescue CD and try to restart now.

  Above always leads to have the black screen with the underscore flashing with the same options available... I'm so lost...

  If possible, I'd like to back up my files I have. I have plans on my computer that I spent working long hours and lots of family photos. BUT if this is not possible (I have not access to a second round to save the files), then I'm more than willing to start again... I want to just that my computer back... I have not even had it for three years yet.

  So any help to get back on the rails would be greatly appreciated... Thank you in advance.

  When you reinstalled, did you remove any third-party system before reinstalling.

  A Mac that runs in Mode without failure, but are generally not normally indicates some incompatible system changes.

• Black screen with flashing '_' in the upper left corner.

  Im running Vista 64-bit Home Premium and recently ran chckdisk because the computer found some "bad sectors" and prompted me to run. After reboot, the computer loads the image in which I can press "delete" to enter the bios (which I do), then press "tab" to go to the post OFFICE (which has no effect and always load the black screen with a '_' blinking at the top left.

  All of a sudden my laptop won't start more. It turns on, displays screen toshiba for a second and then goes to a black screen with a blinking white line in the upper left corner. I can't type something here! The last time I used it it was 100% very well, I have not downloaded anything so I'm very curious to what it might be.

  Hi mate,

  Maybe something messed up to the top of your Windows installation and if the computer may start t more or your HARD drive becomes faulty...

  You can access the BIOS? If so, check if your HARD drive is recognized. If so I think that it of necessary to reinstall Windows. Therefore, take the Toshiba recovery disc.

• Computer won't turn on completely (black screen with blinking cursor) after installing windows updates

  8/7, the following updates have been installed correctly:

  Microsoft .NET Framework 3.5 Service Pack 1 and the .NET Framework 3.5 Family Update (KB951847) x 86

  Update definition for Windows Defender - KB915597 (definition 1.63.1021.0)

  Following this installation, the display resolution has been reset to be very low.  When you try to reset the resolution, I was alerted to a driver problem, so tried installing this in vain (below error code)

  Intel Corporation - display - Intel (r) G33/G31 Express Chipset Family

  Error details: Code 800703E3

  After that, he went to sleep the computer, but was unable to select 'sleep' (it is grayed out) but the stop keys option indicates that the updates were ready to install so I stop thinking which may help.  It was last night.  This morning, the computer was on, seen the screen DELL, then a black screen with flashing white cursor in the upper left corner.  I tried ctrl-alt-del, got the dell screen appears again, then black screen.  I tried ctrl-alt-del, thinking I could try one of the options key F at this time, but he won't even go to this point, the dell blank screen just screen.

  Any ideas would be very appreciated!  It is the second major problem that I had recently after updates vista install (the last time I temporarily lost access to all my files, because they were placed under a temporary user account that had been created!)

  Thank you!

• Black screen with only the mouse pointer

  I just bought a Toshiba with Windows 7 laptop. Black screen with the mouse cursor after a few minutes of no use.  It seems to be the activity of the laptop but nothing happens even with a Control Alt Delete. I noticed after like 20 minutes, the windows screen comes back on.  Any ideas to solve this problem.

  Hello

  Since there seems to be a fairly new computer, you should check with the seller and the support from Toshiba
  for possible replacement and/or warranty repairs. Remember that do you more that they can
  It's something that you don't.

  Check with Toshiba support, their books online and the drivers and their known forums
  questions.

  Why my screen is black when I start Windows 7?

  References to Vista also apply to Windows 7.

  No registration necessary data and re - install Windows 7 might be the best option, but here are a
  few others.

  You can save your files by putting the drive in another computer or an external hard drive enclosure, then
  saving them. Do this using several methods to redundantly. Of course, a real computer
  Shop or the manufacturer of your system can help to recover the files.

  --------------------------------------------------------------

  You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel
  -Double click - Driver tab - click on UPDATE driver - device Manager - map - graph
  then right click on the device and UNINSTALL - REBOOT.

  Another method to try to get to the desktop (try in normal Windows Mode without failure)
  is CTRL + ALT + DEL and the processes tab find EXPLORER.exe and END PROCESS on it.
  then on the tab Applications - lower right - new task - the type in EXPLORER.exe. Safe mode is
  accessible by tapping F8 as you start several times.

  First check this thread in case it is simple and if not to come back to this thread.

  Black screen problems are extremely difficult to repair and all hotfix is usually a hit or miss
  base. That there is no information on a black screen as there is just a blue screen
  adds to the difficulty. Often using a restore point or Startup Repair will have no effect.
  You can try a google to see the proposed repairs, whom some have worked however these
  cover a wide field of efforts.

  Here's a video of one of them.

• Problem re-installing VISTA after the removal of Windows 8 Preview Release, all I get is a black screen with a message "Not found operating system"

  I recently tried Win 8 on my VAIO laptop spare parts on which I ran Vista, after having previously deleted all the files and documents (I don't use often the laptop). Having concluded that Win8 will really work correctly with a touch screen (and the display size was bad as well), I uninstalled WIN 8, understand that I have to re - install Vista from my rescue disks. This I tried successfully a few months previously to make a clean reinstall. However, after removing 8 WIN via the Control Panel, I can't re - install Vista now. All I get is a black screen with a message "The operating system not found" and the rescue disks do not register. What can I do? I like Vista (although I now run Win 7 on my PC) and really want to put it back. Grateful for the advice.

  Well I finally fixed it by tweaking the BOOT BIOS settings and find something along the lines of VAIO Setup. I'm afraid, I just don't remember exactly what I did, but suddenly I found and ran 'VAIO Hardware Diagnostics' gave me a heart when it announced "no error was detected on the Vaio. Then I saw there was an entry for 'VAIO Recovery Utility - Recovery Wizard' and everything started to load. Since the 2 recovery discs I had. Finally, I ran MS Office and Small Business CD-ROM and now everything is back the way that it used to be. Here I had taken more note of how I got to the well Recovery Wizard. I hope that I never have to do it again!

• First HP screen, then a black screen with a flashing underscore

  Hello!

  I bought a new graphics (Asus GeForce GT 740 PhysX CUDA 2 GB) card for my desktop PC (HP Pavilion p6-2067sc) and have a problem. When I put in the card and start the PC the HP screen sometimes maybe 20 seconds and after that it's a black screen with a line flashes in the upper left corner. Ive tried many things to fix it, but have not found ways again, I updated from the BIOS to the latest update from HP.

  OK, I just found out that if I connect the vga input mother board and boot the pc, and after 5 minutes I plug the vga in the gfx card, it shows that windows started normally, and im on the desktop, I now try to install the drivers etc and see if that will fix it.

• Black screen with blinking cursor after the passage in MSC mode

  I followed the recommendation to disable startup secure in the Bios then move the UEFI Bios to the CSM. But when I go to set up what I see is a black screen with a stable cursor in it. And it doesn t go in the Bios.

  The black screen remains.
  I turn off the laptop and once again now, but I still have a black screen with a cursor that is stable and that s it.

  It's like that and it doesn t go to windows even go into the Bios, I can t.
  What should I do?

  Help, please...

  Hello

  After the passage of the CSM and disabling secure boot UEFI mode, you will not be able to boot from the HARD disk as the installation of Windows 8 requires secure boot and the mode of the UEFI.

  Now you can boot from the disc or other media bootable (USB flash key) to install the Windows 7 system.

  I guess you've made these changes installed Windows 7. Right?

  By the way: what model of laptop you have exactly?

• Black screen with mouse pointer count on reboot after installing SP3

  I tried to install Service Pack 3 on a PC running XP Home Edition (new installation).

  Although Microsoft Update has finished installing SP3 and the computer reboots, I get the XP installation screen base with the message "Please wait...". ", which disappears after a few seconds, leaving me with a black screen with only the mouse pointer.

  The mouse pointer moves then the PC broke down, well that no matter how long I leave nothing happens.

  I tried to uninstall SP3 and do it again (when I Uninstall SP3, Windows starts very well) and also uninstall SP3 as well as my Antivirus and try the installation again. But whenever I'm just left whit black screen.

  Try to update with the custom option.  I had problems like this before.  Usually you are missing a driver or something of this kind that makes you hang.  To update while the custom option, with the exception of SP3.  Reboot several times the installation of updates with the "Custom" option  Once all updates have been installed except SP3, you can try SP3 and see what happens.  This usually takes care of it when I have the same problem.
