Hello

When you start your pc, press the F8 key to bring up the menu in advanced mode (you will need to keep tapping F8 after your early pc and passes the BIOS and before windows xp screen screen), select the VGA Mode (if available) and press ENTER. This will start your computer in VGA Diagnostic mode, you should be able to see your screen and connect. After login, click Start-> settings-> Control Panel-> display-> settings-> Advanced-> monitor and select 60 in the drop-down list box.

Click ok on the screen. Perform the normal restart and see if it works.

If you don't get the option for the VGA Mode, select Safe mode and accomplish the foregoing to see if it works.

  • I recently updated my computer (the thing has changed since the problem) and now my LAN is enabled at startup, even if I turn it off before you stop. Why? And how can I stop this?

    Since my last update, that is the only thing changed on my computer since it began, my lan port is always on at the start of Vista (Ultimate).   I'm on a laptop that has a LAN on board.  I have not had this problem NEVER before and have owned the laptop for about two years now.    The only thing that has changed on the computer's windows updates.

    I spent the length of a deactivation of the adapter before you turn off the laptop and tried to load a page that is not in the temporary memory, and get the usual page cannot be displayed.  I scanned for virus using AVG and Bell Internet Security scanner online McAfee.   I also ran Windows MSRT and found nothing unusual.   I also checked to see if the BIOS has been changed somehow, and nothing has changed.   Boot to LAN is disabled.   So I can only conclude that I have a virus has not been detected (but have no slowdowns or anything different in the security under gpedit.msc logs), or the more recent Windows Update changed some settings.

    But weak and this is every time I start up the computer from the local network is enabled.   If I let the cable disconnected at startup, it does not reconnect to the modem cable after rehabilitation and I have to disable and then re-enable the LAN to access the internet.

    Please let me know if anyone else has this problem or have heard of this and know a solution.

    Thank you.

    Hi Lequarius,

    ·          You receive an error message when you restart?

    Method 1

    I suggest that you download and install the updated drivers for the network adapter on the computer by visiting the card manufacturer or computer manufacturer website manually.

    If the previous step fails then I would suggest that temporary you disable the security software installed on the computer and check if the problem persists.

  • Div changed on the site and now everthings gone crazy!

    Hello, I am relatively new to Dreamweaver and make my first website.

    The problem I have is that I ran my model through a site file to check the errors/warnings in the HTML code. Once I did it I found a div (which can be found below) which was not fenced (< / div >). After I shut down my site went a little crazy. I recorded the model without realizing the effect he had but now all navigation and logo has moved to the right and when I remove the modify navigation and logo to go back to normal and then shortens the footer and the décor of the foot of page moves.

    Not sure if the problem is with the div or maybe something completely different which needs fixing, so I'll post both code specific div and also any HTML page to help get a clearer picture.

    On some pages, you have a foot wide, and on the other, you have a narrow foot.

    Removal of the div tags is almost never a good solution for a validation code error.  Obviously that div has served a purpose and should come back into play.  More than likely, something above this div was causing the error.

    Compare the code in a page to work with a non-working page to find your mistakes.  It's the best way to learn what hurts you.

    Hello, I recently created a website for a client. I also created a brochure with a QR code that automatically redirects visitors to a single page in the site. Well, I had to make changes to the site and I had to change the name of the page in which the QR code pointing to. Is it possible to keep the current name of the page but create a page of automatic redirect named like the QR code? Basically, the brochures have all been printed already, so I need the QR code when analyzed in order to continue working. Now, it is not the case.

    Nevermind, I figured it. I've reproduced the page, renamed the QR that indicates the code of the page, and then he hid in the menu of page properties.

  • When I change the setting by LabVIEW on my device, I see change on the monitor of the device?

    When I change the setting by LabVIEW on my device, I see change on the monitor of the device?

    This question should be addressed to the manufacturer of the device. From your previous posts, I guess you use GPIB or serial. If the unit has received the order, the manufacturer should be able to tell if no indicators on the device to update when the order is received. Based on my experience, however, the device indicators will most likely update on receipt of an order successfully.

    Got paper stuck in the printer and now will only print proofs. How to reset the printer

    It looks like you may have some saved jobs in your queue that need to be removed.

    Here's how:

    To clear the print queue, stop the print spooler service and delete all the jobs/print pending.
       
    You cannot delete all print jobs in the queue so that the Print Spooler Service is running.
          
    To stop the Print Spooler Service, click Start, run and enter in the box:
           
    services.msc
           
    Click OK to open the Services Applet.
           
    Locate the Print Spooler Service, right click and choose 'Properties' and then click on the "Stop" button to stop the Print Spooler Service is running.
       
    The option "Startup Type" of Service properties print spooler is usually set to "Automatic" (which is now a good time to check it out).
       
    If the "Startup type" is not set to "Automatic", set the "Startup type" to "Automatic" If that is your desire (which now is the time to check it out).

    Do not try to start or restart the Print Spooler Service immediately.  You must remove all print jobs backed up first...
       
    Then, delete all updates pending upward and forward to printing from XP.  If they do not print before, you will need to send the to the printer again.
       
    Using Windows Explorer, navigate to the following folder (assuming that Windows is installed on your C drive):
       
    C:\WINDOWS\system32\spool\PRINTERS
           
    Delete all the print jobs in queue (select and delete all the files) in the folder if the folder is without waiting for print jobs.  The folder must be empty when you are finished.
           
    Reboot your system and check the Print Spooler Service again to make sure the Print Spooler Service restarts automatically restart (given that the startup type is set to automatic).
       
    After the reboot, check again the Spooler Service for printing and the 'Status' column for the print spooler must be read "started."

    Submit new failure of print jobs.
