  How to troubleshoot an installation fails on Windows XP Service Pack 3
  http://support.Microsoft.com/kb/950718
  Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.
   
  Note: A firewall is software or hardware that checks information coming from the Internet or a network. Then the firewalleither blocks information or allows information to pass to your computer. If the information is blocked or throughdepends spent on your firewall settings. A firewall can prevent malicious software (such as worms) to access your computer through a network or the Internet. A firewall can also help stop your computer from malware sent to other computers. Windows XP, Windows XP Service Pack 2 (SP2) and Windows XP Service Pack 3 (SP3) include firewall software.

  http://support.Microsoft.com/kb/950717
  Note: Disable your antivirus software is not usually recommended, some software antivirus prevents certain system changing files. This can cause the Windows XP SP3 installation failure. To make sure that you manage to install Windows XP SP3, temporarily disable your antivirus software, including any third-party antispyware and firewall program. To do this, right-click on the icon for your antivirus program, and then click on disable. The antivirus program icon typically appears in the bottom right corner of the computer screen.
   
  Important: Make sure that you enable the antivirus software after you install Windows XP SP3.

  Everything works OK.

  Thanks for your help

  Everything works OK.

  It seems that it is not... Why Dutch? You use or have the corresponding language version installed?

  Free translation of message:

  Please note that ntoskrnl.exe is a process in the cycle of the initial startup on your computer program.

  Try to load your "last known good configuration".

  The issue is also known to be caused by a short circuit in the ground cable into the keyboard cable. Make sure that it is not the cause of your error by replacing the keyboard with another keyboard or just disconnect the keyboard from the computer. You can also look at your function "Add or remove programs" If KB2686509 <> http://support.microsoft.com/kb/2686509 > is installed.  Install manually if it is not.

  ===========================================

  Think about it an absolute must - manually update your drivers.

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded
  on your system. For each driver in the list, additional useful information is
  Poster: load address of the driver, description, version, product name,.
  company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit Maker as replacements and system manufacturer of device which are
  the most recent. Control Panel - write - graphics card - device manager
  the brand and complete model of your video card - double click - tab of the driver-
  Note the version information. Now click on UPdate Driver (this can do nothing
  MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
  This will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard
  If there are 3rd party with their own software and drivers and the other main device drivers
  you have.

  Now, go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restore)
  and site (Realtek, Intel, Nvidia, ATI, for example) and get the manufacturer and device
  their latest versions. (Look for the system to update the BIOS, Chipset and software updates
  Site of the manufacturer here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN -.
  REBOOT after each installation.

  Always check in the Device Manager - drivers tab to be sure the version you are
  installation actually appears. This is because that some rollback of drivers before the
  later is installed (particularly that audio drivers) so install a driver - reboot.
  Make sure that it is installed and repeat if necessary.

  Repeat to the manufacturers - BTW to the device makers DO NOT RUN THEIR
  SCANNER - check manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
  http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

  Installation and update of drivers under Windows 7 (updated drivers manually using
  the above methods is preferable to ensure the latest drivers from the manufacturer of system
  and device manufacturers are located)
  http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

  If you update the drivers manually, then it's a good idea to disable driver facilities
  in the updates of Windows, which leaves on Windows updates, but it will not be installed
  pilots who are generally older and cause problems. If updates provides a new
  driver then hide it (right click on it) and then go get new ones manually if
  you want.

• Satellite L355 - dreaded blue screen - Bios does not end

  I have a new Satellite L355.
  Sometimes at startup I get the DBS.

  Otherwise said, the bios does not end and the screen is blank.
  Laptop repair center replaced the motherboard twice, but I still have the problem.
  I found that if I turn off the power and remove the battery, I can start very well after the replacement of the battery.

  Does anyone know why the battery clears the problem?
  Toshiba technical support often has a user that to clear a trouble report. They must know something.

  Thank you, jack

  > Occasionally when booting I get the DBS

  That would mean that this sometimes happens from time to time but not always
  Is this good?

  I think that it of difficult to say what's going wrong here because the question is not always happens... so it is difficult to replicate it
  Usually if the POST (power on self-test) cannot transmit properly then that would mean that a material error has been detected somewhere on the map

  Maybe you should check if the laptop using the latest version of the BIOS.
  If a new BIOS has been published, then you should try to update.

  Make sure that Windows is updated appropriately that there have been several USB updates.

  1 check that the driver letters for them, for a player, if the drive of the default drive letter is changed, what is happening.
  Mine was h: I added a device that took H: and the player stopped. So I put it back to H: and the other
  device to J: and everything worked again. If necessary start - type in the area of research-> disk management find top
  -Right-click on it - RUN AS ADMIN

  Don't forget to remember the MP3 must be set to the PSG to sync with WMP, and meteorological service of Canada to copy and delete files
  and update the firmware.

  If no joy follow these steps:

  You may need a powered hub. (all the USB ports on your computer are not powered, often only 2)

  Try these:

  Make a Restore Point

  Control Panel - Device Manager - click in the empty area - VIEW - show hidden devices

  Here, your devices are the MP3 player.

  Now look everywhere EXCEPT the USB controllers for your devices (cannot be found) and if you find
  It RIGHT CLICK and UNINSTALL all.

  now go to the USB and UNINSTALL ALL controllers in the category, but the category itself.

  APPLY/OK

  RESET

  This refresh battery USB and hopefully it will allow the unit to install. (You may need a powered hub)

  Here is the similar procedure under XP, Vista is the same, except that we need clear specific devices, as appropriate.
