have the boot device from Windows 7 - laptop screen - black - not found -.

Compaq Presario screen - Notebook PC - black, start the device not found - install an operating system on your hard drive - hard drive - (3FO)

Did you try what is called a "Hard Reset"? It is 1. Withdrawal of all devices such as printers. 2. disconnect the power supply input cable. 3 remove the battery. 4 press and hold the power button for 30 to 60 seconds. 5. reconnect the power cable and install the battery. 6. power on and boot mode safe (assuming that the screen comes alive). I read a post from someone who said he had to go through this procedure 3 times before their recovered laptop but I found my laptop recovers with a reset, as described. I have, however, to do this twice

in recent weeks, but I can't find any explanation as to why this error occurs. If someone can tell me I would be grateful.

    Besides what abdelhak says:

    The message of PXE boot that you receive when you start your computer has nothing to do with your CD/DVD-Rom drive. Your computer uses a PXE boot method to attempt to load Windows from a location on your network. Since you do not have this configuration, it is safe to ignore it. If it slows down the startup time of your system, contact your manufacturer and ask them for instructions on how to "disable PXE Network Boot of the BIOS.

  • Where to get the authentec fingerprint drivers for various computers laptops hp that supports the functionality of the biometric device in windows 7?

    Hello

    We build a Windows 7 SOE for a large company that takes care of many models of computers laptops hp. Each of these laptops comes with a fingerprint reader, and we would like to use the built in support of fingerprint (biometric devices) reader that is running windows 7. The models that we support are as follows:

    • HP 6910P
    • HP 6930p
    • HP 8510w
    • HP 8530w

    We tried using the drivers of fingerprint Authentec (aes2501a) on the hp website, but after the installation, the biometric device option is not in windows 7. We contacted HP about this and they said that we must use the driver coming from windows update before this option appears. After installing the driver from windows update, the option of the biometric device seemed that hp said. Therefore, because of the way that our SOE is built, we demand that the executable that is identical to that on windows update. Anyone know where we can find packages both x 64 and x 86 for this device driver, which are the same as those found when you go to update windows on these machines running windows 7? Let me know if you need any clarification.

    Thank you

    Hi Mustapha ETS.

    Step 1: Locate the stand-alone file by inserting the device model number
    a. visit http://catalog.update.microsoft.com/v7/site/Home.aspx
    in the search box, enter the model number of the perimeter search of the driver.
    c. download the right driver for your windows and install it successfully on all computers.

    Note: If there is no available stand-alone file, I'm afraid you'll have to visit update of Windows on all computers and the installation of the update done or contact the device manufacturer to obtain the driver.

    Cannot find any other relevant catalogues on the site Windows Update Catalog (which is X 64).

    I downloaded a game and I'm going to open and it says Windows cannot access the specified device, path or file. You can not have the appropriate permissions to access the item.

    The thing is I had this game on this laptop before and worked fine.

    But every time that there is a update for the game, you have to uninstall it and then reinstall it.

    When I reinstalled it.

    I now get Windows cannot access the specified device, path or file. You can not have the appropriate permissions to access the item.

    What is the problem?

    Hello

    Thanks for the reply.

    You can try to temporarily disable the antivirus program and check the results. It can also occur if you have not enough permission to run the file.

    Caution:

    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.

    Hello!
    So I'm at the end of my rope with this one... it lasts for months, and I keep revisitng every two weeks to try and fix that and every time to be completely frustrated.  I found this forum tonight, so here goes...

    We downloaded a few games on the HP Games Web site.  We download them and everything works fine.  Then, we will open the games and this pop up error message:
    "Windows cannot access the specified device, path or file.  You can not have the appropriate permissions to access the item.

    These games used to run fine, and I have no idea why they now have problems.  We have a Vista operating system, 1 account who is the administrator, the Parental control is disabled (or if we believe).

    If anyone can please help it would be much appreciated!  We have a monthly membership to this site of game and continue to accumulate credits, but may not use it.  It makes us crazy!

    Thank you in advance!

    Hello Heathie,

    Thank you for posting.  It seems that the program is no longer on your computer.  This can happen if the game files are deleted, but the game itself has not been uninstalled correctly.  I recommend you to download the game again to a location on your computer where you can easily find and install it.  This should fix the problem.

    Please let me know if this helps you.

  • Windows could not get a list of devices from Windows Update. Try again later

    Original title: Windows 7 list printers cannot be updated
    I installed a windows 32 bit 7 OS several weeks ago on my workstation Futitsu-Siemens and followed the instructions on the HP Wizard to try to install the HP Deskjet 990c printer driver for my HP 6122 printer. According to the HP Wizard, the only way to do is to update the list of printers by clicking on the "Windows Update" button in the dialog "add a printer".  I clicked on this button several dozen times in recent weeks, and every time I get the message "Windows could not get a list of devices from Windows Update. Try again later.

    I installed a windows 32 bit 7 BONES of several months on my HP laptop and the printer list updated without a hitch to include many more HP printers that are on my computer Futitsu-Siemens including HP 990c.

    What should I do?

    Here's what I found my system which is an Z210 64 HP running windows7. I just updated my Bios to v1.35

    What I did to get the update to work once and what I have to do each time to add another printer by using the Update window.

    1. open (Ctrl-Alt-Del) Task Manager

    2. click on tab of abuse, then Services button (bottom-right)

    3. under the name to find "Windows Update".

    4. right click "Windows Update" and select stop. do not close

    5. open the Exploper window and browse to C:\Windows

    6 delete the folder "C:\Windows\SoftwareDistribution".

    7. go back to served, right click on "Windows Update", and then select start

    Now the "Windows Update" button should work. For me I have to do every time I have to install a printer that requires me to use windows update

    Looking for what casues the error

    at the bottom of a file named WindowUpdate.log located in C:\Windows after that I get the message "Windows was unabel to...» "I have this text below.
