My dell optiplex 740 will not start.  The screen is black, once it displays the Dell logo.  It does not say that the computer is in mode 'sleep'.

  1. Did you the latest changes on the computer?
  2. When was the last time it was working fine?
  3. You receive an error message?

Method 1

See the articles below and check if it helps.

Computer stops responding with a black screen when you start Windows XP

After the Windows Logo appears or after you log in to Windows, a Windows XP computer cannot display the wallpaper, a black screen or a blue screen

Method 2

I suggest that you start the computer in the last good known Configuration mode and safe mode, post back with the result.

Method 3

If the computer can boot in any mode, then I suggest that you perform the clean boot procedure and check if it helps.

It is possible that some third-party programs installed on the computer is causing the problem.

To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

See section to learn more about how to clean boot.

How to configure Windows XP to start in a "clean boot" State

(b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

(c) under the general tab, click the Normal startup option, and then click OK.

(d) when you are prompted to restart the computer, click on restart.

  • Lose my ethernet internet connection when the computer goes into mode 'sleep '.

    I have a desktop with Windows Vista.  I have my internet through a cable company.  I've never had problems of connectivity for 2 years and then out of no where he would pass the signal after mode 'sleep'.  I had the cable company come out and check on all equipment and it's good that now, I'm still clueless and confused.  The connection icon have an exclamation point in a yellow triangle and say "limited connectivity" and «identify...» "and then I click on Local area connection status and make a diagnostic test that will get me connected to"network 2 "until it goes into sleep mode and then the process repeats.  It's boring say the least.  When I login and go to the LAKE State he says;

    IPv4 connectivity: Internet

    IPv6 connectivity: limited

    Media state: enabled


    Speed: 100.0 Mbps

    He said that the issue is resolved after each diagnostic test, but then it happens again.  I need some help pleaseeee!

    > I need some help pleaseeee!

    But you're in the wrong group! It is a problem with your network driver
    or your Windows installation. You have this repost to a suitable for Windows Vista
    Forum. It is possible that a newer driver from the network has a problem with sleep
    mode, you should try another pilot (older or newer).
    From your description, there is a problem to renew the lease of your
    DHCP server (which must be running on your router), it does not use the
    IP address assigned earlier or he does not do / IP address (which
    should be the same) we get the router. It is also possible that the
    problem is with the router or a new firmware on this subject. You should study
    These two avenues, including a replacement of the router and firmware.
    Another very simple solution is to configure your PC for a static IP number and
    leave it like that. In the forum, I mentioned, people will be able to talk to you
    through this option if you don't know how to do this.


    IEFAQ: Newsgroup:

  • Cannot defragment the hard drive AND cannot start the computer in safe mode

    I have been unable to defragment my hard drive because it tells me that chkdsk /f planned.  I tried manually works in command mode nothing works.  I was advised to try to start up in safe mode, but when I do that all I get is a screen of command lines, and my computer freezes there.  What I'm doing wrong and what I can do differently?

    If you try to defragment a volume and see a message like this:

    Disk Defragmenter has detected that Chkdsk is scheduled to run on the volume: (c :))
    Please run Chkdsk /f.

    This means that the volume (disk) that you want to defragment was marked 'dirty' XP.

    The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

    The afflicted system has a working CD/DVD (internal or external) drive?

    You have a genuine XP installation CD bootable, which is the same Service as your installed Service Pack (this is not the same as any recovery CD provided with your system)?

    You can check the status of your bit of impurity from a command prompt window.

    To do this, click Start, run and enter in the box:


    Click OK to open a command prompt window.

    For example, to query the bit of impurity on drive C, type:

    fsutil dirty query C:

    The sample output:
    Volume c is dirty
    Volume C: is dirty

    Is the volume of your sale or it is not dirty?

    The only way to disable the on a volume's dirty bit is to run chkdsk with error correction.

    You can click on start, run and enter in the box:

    Chkdsk /r

    Click OK and answer Yes to schedule the chkdsk next time XP restarts, restart your system and keep your fingers crossed that the chkdsk /r clears the dirty bit (you may need to run once or twice).

    If who disobeys, then you will need to start in the XP Recovery Console and run the chkdsk /r from there.

  • I tried to start the computer in safe mode, nothing works. All of a sudden my icon text in paint is dark. Why?

    Found the answer... the text bar is still gray but I was able to unlick

    in the toolbar and I was able to add text.  Not sure, maybe "text".

    the button was grey all along?  I don't think, but I can choose only three of

    the four options that allow a check mark in the view menu: toolbar, color and the State.  The text

    has a check, but it is gray, cannot be enabled or disabled.  Maybe I just never noticed it before.  Could

    Add text by clicking on the toolbar tools, then reclicking thereon.  Odd.  It works and that's all that I needed.

    Original title: appearing automatically jump to the top of websites and to hear the mouse click as sounds radomly
    Microsoft community.
    I have essentially two problems in my computer.
    (1) since almost a month my computer automatically goes into safe mode when I pass it on or restart. So, I have to change the user account to come to normal mode.
    (2) in addition to this since 5 days I noticed pop-up program (exactly which is the site web ) in the right corner of my computer screen and it comes with random noise (similar to a mouse-click) that I mentioned earlier.

    I guess this program automatically installed when I tried to download another program almost a week back.
    I tried to remove the program using Control Panel, but it is not in the Panel.
    Then I ran a Kaspersky internet security scan (license and currently updated version) that was installed in my computer and then I ran Microsoft security scanner and none of them could picked up a problem.
    So I ran computer more secure mood.
    When I tried to clean the boot. I noticed only with safe mode even if the clean boot dialog box appeared options such as ok or cancel orders are not visible or they are absent (or damaged). Here, because I couldn't do the clean boot function properly.
    And I always get that previously mentioned his pop-up at random.
    So I am worrying because this could be the virus and it can harm my computer or your identity. I really appreciate if you can help me in this regard.
    Thank you
    Kind regards.
