Won't boot NB205 - black screen and white flashing underscore

• Boots Vista black screen with white cursor and nothing else (Black Screen of Death)

  After a download from Microsoft update last week, my system has rebooted. He first had a screen blue error, rebooted, reported a disk error and automatically run CHKDSK. Since then, the system has started a black with white slider screen and nothing else. This happens at startup options (Normal, safe, safe with the last command good known configuration). Not even sticky keys would come to the top. CTRL-Alt-Delete, Ctrl-Alt-Esc and all other keys has nothing did. Even with a right click.

  I searched all over the web for solutions. I found (and tried) several over the past week, but nothing has worked.

  Here's what I tried...

  F8 held key on boot to the top and entered the startup recovery. Ran of recovery. Initially so found of disk errors. Those fixed. Then he said he could not repair the system and reported two pilot errors.

  Tried system restore. He said that I had no restore points (even if I know that I had before).

  With the help of recovery options, I went to the command prompt. Asked to RegEdit and load the Software hive. Checked the connection entry Windows NT; made sure, it has been set to explorer.exe

  The system, checked RpcSs Key hive. Already the NT AUTHORITY\NetworkService value

  Renamed event connects winevt and not create the Logs folder

  Removed the hard drive. Attached to another system (as slaves), and the registered file permissions. They have screwed everything up. The fixed file permissions and drive put back in original system.

  Œuvres self-retaining keys now. Do not, however, as my sticky keys doesn't have a link to configuration.

  Went back into recovery startup via the F8 key at startup. Now, when I run start recovery, it says that everything is going well and there is no problem.

  I have download the hotfix from article 977675 Microsoft, but I don't know how I can apply it without being able to get into windows. I would like to contact MS e-mail or chat support, but I can't get the product ID without being able to connect (frustrating talk).

  I would like to reinstall OS, but HP does not provide an installation disc with their systems (only a full restore partition). My system is backed up (with the exception of the Windows folder), but I really don't want to have to make a full recovery, as I have a lot of specialized programs and settings that would probably take me a week to re - install and re - set.

  Anyone have any new ideas?

  Hello

  Here's my usual BlackScreen convenience store, because it may be that you haven't tried
  or if you have access you might be able to come back and start some of them.

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

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

  Another method to try to get to the desktop (try in normal Windows Mode without failure)
  CTRL + ALT + DELETE and on the tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - then
  on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is reached
  by tapping F8 as you start several times.

  Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
  That there is no information on a black screen as it is on a blue screen just 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

• 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.

• dv5 1002nr difficulty for the black screen and 2 flashing lights

  Hello!

  So I have this laptop (dv5 1002nr) and of course just after the warranty goes out did the laptop. This original computer was one of my friends who took to Best Buy Geek Squad and they told him to fix this laptop it would cost $400 if not more.

  So to make a long story short, she got a new computer and I helped get parameter and everything and then I asked for this laptop (I have set now free) did not work if I could have. He was a useless piece of junk so she agreed.

  After about an hour of resistance tests, transistors, etc., I can verify that all energy through the computer is as it should. I spent maybe 30 minutes on Google without success, and finally I decided to try everything. I started with the new ram without success. I tried all the silly little "trouble shooting tips" HP has for this laptop.  I'm running a little more than 2 hours working on this seemingly useless task when I finally managed to make it work.

  I did about 3 - 5 times now and it works every time.

  First I remove all the ram and then turn it on. (of course it doesn't)

  Turn the power off.

  Then remove the processor and turn it on. (attention)

  Disable.

  Put the processer back in and turn it on. (still not working)

  Disable.

  Put the ram back in and turn on.

  That's what I did and it works every time for me.

  Since I was only 17 and a little short on money I can't go just around portable computers purchase like these with this problem and test this further.

  If anyone has this problem please try this and let me know.

  Oh and HP. thank you very much your 'support' really helped me... at the expense of my portfolio.

  Oh and one thing...

  I did the 'live chat' and they said that my laptop having is not a display might be due to my hard drive or the motherboard.

  1. the hard drive would not effect my monitor does not. Or on a hard disk of the computer AFTER.

  2. except when he said to the motherboard he also lies the processor he was wrong, once again.

  3. it is a faulty laptop and I know other people have had this problem I hope, they read this insead of wasting their time with "HP support".

• Invalid product key, left my computer with a black screen and a cursor of the mouse on the boot.

  A few days ago, I tried to upgrade Windows 7 Home Premium (64 bit) to Windows 10 using the free update. Installation hung at 84% for 2 hours, then restarted, was unable to recover the installation and then could not get back to Win 7. This left us with a black screen and a cursor of the mouse on the boot. The computer would remain in this State for about 10 minutes and then reboot and repeat.

  Fortunately, or so I thought, I had a few CD Windows installation backup from the back to the era of digital river. So I thought I'd install fresh on my empty partition, copy my files and data, and then format the partition with the installation broken on.

  I did, but now he tells me that my product key is not valid and cannot be activated. The product key came on a real label on the PC when we bought it.

  The key is for X 16-96072. I installed X 17-58997 (Windows 7 Home Premium x 64 with SP1 (u)). I don't know what is the problem with the key? Should I have installed without the (u)?

  One key 25 digits grouped in 5 sequences of 5 characters not X 17-58997.

  To analyze and solve problems for Activation and Validation, we need to see a full copy of the diagnostic report produced by the MGADiag tool (download and save to the desktop -http://go.microsoft.com/fwlink/?linkid=52012 )
  Once downloaded, run the tool.
  Click on the button continue, after a short time, continue button will change to a copy button.
  Click the copy button in the tool (ignore the error at this stage) and then paste (with r-click and paste or Ctrl + V) in your message.

  Step 2: If SFC help not try to run the disk check in the command prompt.

  Type the following command and press ENTER:

  CHKDSK /scan

  Important: All performing hard disk the disk check if bad sectors are found on the hard drive, while the bad sectors can be refunded, but there may be loss of data.

• Satellite Pro L450D black screen and will not respond to any keys

  Hello

  My niece has used his Toshiba L450D for almost a year now and he really liked it, who was until last month. She turned on her laptop and when she presses the button of the mouse, the button cracked and he fell into the laptop.

  Now my brother contacted Toshiba and I was told because it is under warranty it might return for repair because it was a common fault. Then he he packed in loads of air bubbles and a box to make sure it was safe.

  A few weeks later he came back repaired but we were all shocked that the laptop was put in a very loose box and you could hear this rattling noise. When we turned on the battery was flat and we had a new boot menu.

  As she installed it Windows 7 laptop would boot directly into Windows 7, but now after the repair of the laptop shows a menu black screen with as follows:

  + Windows 7 +.
  + Recover Windows to Factory Settings [active EMS] +.

  So we started in Windows and everything went well, but now after 5 or 10 or even 20 minutes, laptop displays a black screen and will not respond to keys or mouse movement. There is nothing on the screen its just black.

  I started in SafeMode (which was more difficult with the new menu) and it does the same thing. I even managed to do a virus scan quick who took 3-4 minutes and was clean.

  I would like some advice on what my niece is very angry, and it's difficult to explain what is happening to a child in the primary school.

  Any help would be grateful.

  Hello

  Have you tried the option of HARD drive recovery?

  If this is not the case, try to set the notebook back to factory settings using HARD drive recovery.
  Turn on the device, press F12, choose repair my computer, then select Toshiba HDD recovery.

  I hope it will work!

  Everyone everyone please help!

  Hello

  Looks like a hardware malfunction on your laptop, because normally these beep codes mean that it s something wrong with the hardware.

  Is that what you have installed extra RAM? If Yes, remove it and try to boot with original RAM only. Also try to reset the RAM in the slot.
  It work?

  In the worst cases, you must go to an authorized service provider. Technicians can check the laptop and determine the cause of this problem.

• When I was playing the game and my 3D PC show the black screen and the sound of noise.

  Hi Admin,
  When I was playing the game and my 3D PC show the black screen and the sound of noise. And then I can't move anything and I can restart only. What is this problem? I don't know why? Please help me what should I do.
  My PC specs are as follows

  Aspire M5800 (Q84MR375) Genuine Windows Vista® Home Premium, 64-bit, Intel Core 2 Quad processor Q8400 (2.66 GHz, 4 MB L2 Cache, bus front at 1333 MHz), 3 GB Ram, 750 GB S - ATA HDD, DVD SuperMulti Double Layer drive, Nvidia GeForce GT220 graphics (1 GB dedicated RAM) card, Wireless LAN, keyboard and wireless mouse with LCD 23 '' monitor.

  phoechan,
  More than likely if this started after you upgrade to Windows7 then you might have to update your hardware drivers.  Go to the websites of the manufacturers of hardware for your PC and get all the latest drivers for Windows 7 (video, sound, chipset, etc...).  If they don't have Windows 7 drivers you may have questions until they create them.  You can also try to boot your PC and also right click on the game .exe file and change the compatibility mode to Vista or XP.
