  If the HP recovery process does not work, it seems to be a hardware problem.

  And now that you mention have a blue screen.

  If it was a software problem, the process of HP recovery to reinstall the operating system should fix (take it back in new condition).

  And this new condition would exclude any incorrect hardware drivers may have installed the original problem.

  Have you tried HP support?

  http://WWW8.HP.com/us/en/contact-HP/contact.html

  Or assistance HP Forums:

  http://h30434.www3.HP.com/

  See you soon.

  Edit:

  HP recovery process, you get the possibility of a destructive or non-destructive restore. If you use non-destructive recovery option, often have the same problems continue.

  The problem continues when you use destructive recovery too.

  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.

• Windows XP home version suddenly does not, even in safe mode.

  My computer at home is no longer operational. Windows XP Home version has suddenly refused to load. It seems to start normally, but never ends. I tried to boot in safe mode. Although safe mode starts to load, it does not end. If I try to start normally or in safe mode, there is no error message. A few years ago, I bought the computer with XP preinstalled. It's never happened before. I have all the updates, including service pack 3. However; I realize now that I did a backup disk. Any advice as to what are my options?

  Given that your machine does not start, you need to start a system on a CD.  Easier to create CD's free Linux Livecd such asKnoppix.   If you have a friend with an XP installation disc, you can try to build a diskBelia PE or Ultimate Boot CD for Windows . On the chances that your problems of a corrupted registry, you can boot from that disk and use it to perform the steps in

  "How do I recover from a corrupted registry that prevents Windows XP startup"
    <>http://support.Microsoft.com/kb/307545 >

  With a Live Linux disk, you can pick up the procedure in part 2, step 6 using Linux to copy, paste and rename the appropriate files.  If all else fails, you can use the same Linux Live CD to backup your data on a USB drive or a network drive before reinstalling Windows.  Most OEM computers have a recovery partition which is activated by pressing a particular key at the right time to start.  This procedure will completely erase the drive and put it in the State that it was when it was first purchased.  Quickly look up when you boot.  It is not stay there long.  If this does not work, you will need to get a replacement from the manufacturer of your computer installation disc.

• XP labors heavily and Will does not start (sometimes even in safe mode.) "And if it starts in the DM, it will freeze when I try to enter to change anything).

  I have a XP computer. During use, the power supply cord unplugged and computer is dead. When I tried to restart it, it will go to the blue screen with an error, go to the screen that asks if I want to start in safe mode. It does not start in normal mode, but it does get my wallpaper and stay there. Sometimes Windows XP screen and stay there. It really starts to make a lot of noise when one of these things happens. Don't know what to do. I have a XP OS disk Dell provided with the computer. Any ideas?

  Repair the Windows XP installation - you should have all your files intact.

  A repair install will replace the system files with the files on the XP CD used to the repair facility. It will leave your applications and settings intact, but Windows updates will have to be reapplied.

• Blue screen. Windows does not start. Even on Safe Mode!

  When I turned on my laptop the windows logo and everything is in place. But then comes the black screen and ask the options to start windows normally, start in safe mode, ect. I chose to start normally, then a blue screen appears which says that the computer has shut down to prevent damage. He said that I had to disable all anitivirus and other things that I don't have to read. I tried every other selection as start in safe mode, start in safe mode with command prompt, in the other options, I get the same blue screen. I really need to get this problem fixed. I have no CD of installition XP, I have no CD of restoration, I have nothing to work with, so I just need to know a way around it.

  There is no magical way around that without any installation disc. Most laptops come with a picture of factory restore on a special partition on the hard drive. The factory restore process is normally called by pressing a key of function (such as F11) to start the computer. There will be a message as to what function key press the screen when you start your computer. You can also consult the manual of your computer or the computer mftr.'s site, or contact technical support to learn how to restore your computer if you plant from each computer mftr. He does it differently - sometimes even between models.

  These machines also generally have a utility to create physical recovery disks in case the hard drive needs to be replaced or the factory restore image is somewhat damaged. If you have not created the recovery image recovery physical and damaged disks, contact technical support of computer mftr. to order a set of recovery disks. It is normally very expensive, around $20-25.

  Before you try to restore the computer, you must determine if the material is good. You can test yourself:

  http://www.elephantboycomputers.com/page2.html#Hardware_Tshoot

  A good troubleshooting step is to start with a Linux Live CD. I like Knoppix, but there are others. This has two advantages: 1) if the system works, you can back up all the data that missed your last backup; and (2) with the machine running Linux allows to determine whether the problems are caused by software or hardware. If the machine is unbearably slow and/or Linux cannot run correctly, you know that the hardware is at fault. If the machine behaves perfectly under Linux, you know that the software (Windows) is at fault.

  If the equipment is faulty, if you replace it or not depends of which component is bad and the age of the machine.

  If the material is good (maybe Windows has been severely infected with a virus/malware and that's why he no longer starts for example), then perform a restore if you plant using any method has been provided by the computer laptop mftr.

  If you can't do the work yourself (and there is no shame in admitting this isn't your cup of tea), take the machine to a professional computer repair shop (not your local equivalent of BigComputerStore/GeekSquad).

• Firefox crashes until he could start up, can not even in safe mode.

• Since the update of FF 8/9, many Web sites does not, even in safe mode. Any idea what the problem might be?

  All sites worked fine before v8.0 and 9.0. But now many sites (for example, newegg.com & baltimoresun.com) won't load. I hit the button reload several times before that something appears on the screen at all. I tried safe mode - no help. I disabled javascript, which helped some, but does not cure the problem, since even with him off a few sites still never finish loading. I've also disabled IPv6 and DNS Prefetching and emptied the cache, all to nothing does not. He seems to graphics that are not loading. Someone has an idea what is the question? I swear that I'm ready to switch to Chrome or Solaris, if I can't solve this problem. It's incredibly frustrating.

  Well, the problem was caused by the upgrade to v8.0 corrupt something in my profile. Create a new profile loading problem disappear, this is the fix for this particular problem. Significant pain for sure, since the creation of a profile "duplicate" isn't a very elegant process in FF.

  WARNING: If you try this fix, be sure to first make a backup of your current profile. (When I deleted my original profile in the Profile Manager, it also - incredibly - deleted the files that I had copied to my new profile.) Any thoughts on that, dev team?)
