Device not installed properly message

i think the realtek PCIe controler is your video display controler

Windows is likely crashing while loading recently upgraded device drivers. The most common culprits for this scenario are video drivers.

The next time you boot, as soon as you see the Dell splash screen, start tapping the F8-key about once every second until you see a white on black menu. If you see the Windows logo, you missed it (try again, this time start tapping the F8-key a little before the Dell splash screen).

This menu will allow you to boot Windows in "Safe Mode", which will bypass any non-essential drivers and applications that could be causing the crashing. Select "Safe Mode with networking".

Assuming the computer booted fine in Safe Mode, you will be able to remove the troublesome drivers. You will see an informational message about Safe Mode, which you may close at any time. Right-click "My Computer" and select "Manage". Wait a moment for the Computer Management window to appear. Then, click on "Device Manager". If Windows was able to identify the faulty driver, it will appear in the list with a bright-yellow triangle. If this is the case, right-click and "uninstall" it. If it did not show up, first click the tiny white triangle next to "Display Adapters" and "Monitors" to open those categories. Then, right-click and "uninstall" everything listed within the two categories. Your computer will probably boot normally after doing this. But, try and find the proper driver for you video adapter before rebooting if possible. I recommend also re-installing the chipset drivers which may be related to the problem.

To attain drivers for your specific Dimension B110, visit the following link and enter the service tag code on the back or side of your machine: Dell Drivers

your power supply board, probably has some bad caps in it

there must be the problem of your lcd backlight chek that properly by open it or tack it to the engg.near you.

If the monitor displays POST messages as it boots, then your monitor is still working. It would appear that either your video card or your monitor settings need fixing. Try booting Windows in SAFE MODE and go to Control Panel. Select Display Settings and uninstall the existing driver for your video card.
Reboot your machine. Windows should detect your video card and install its proper drivers. If you've gotten this far, your monitor is working.
Failing the above, reboot in SAFE MODE again and this time uninstall your monitor. Try rebooting again and Windows should again detect, configure and install your monitor appropriately.
Good luck!

Hi,
Have you ensured that your display card driver AND correct monitor driver is installed. This is to make sure that your display card only generates signals that your Acer monitor is capable of handling. If you do not have the driver CD for your monitor you can download the software from www.acer.com. The problem is most likely that your display card is generating a refresh rate which your monitor cant handle. Go to your display properties and lower the refresh rate of your display card and see if this solves the problem.
Best wishes,

Sounds to me like the input has gone out of the boundaries the monitor supports. IE the refresh rate is too high frequency (normally 60 to 72 Hertz for LCD's) or the screen resolution has been set too high.

Go into safe mode and set it back to 1024 X 768 at a frequency of 60 Hz, once back into windows proper you can try higher resolutions and change your refresh, if the screen goes black or displays a message "Out of Bounds" or similar it should revert after 15 seconds if left alone.

Have fun

Getting dual monitors to work correctly seems to be a hit or miss affair. In many cases, it's just a matter adding a second video card and monitor and rebooting the computer. In other cases, you need to do some cyber gymnastics to get things working correctly.
The process is the same no matter which version of Windows you are using. First, be sure that your system is working correctly. Boot into safe mode and verify that you have only one video adapter and monitor showing in the Device Manager. If there are more, but you only have one adapter and monitor, you'll need to remove the extras.
Once you're sure that your video setup is working fine, turn off the system and look inside. Remember that you'll need a video card for each monitor that you plan to run under Windows. That means that your system must have a free expansion slot for each one. You may find that you have problems with IRQ sharing or DMA channels, depending on your motherboard and video card, although many video cards seem relatively intolerant of IRQ and DMA conflicts. Install your video card in the appropriate slot, and then connect the monitor.
Restart your system. If all goes well, your computer will boot the same way that it always has…the second monitor will still be dark. If your system prompts you to login, do it. You may need to install drivers for your second video card, depending upon whether or not Windows has built in drivers or not. Just follow the on-screen instructions.
Once the drivers are installed, check the Device Manager to make sure that the display adapter is properly detected:
Once the drivers are installed, open the Display Properties window. In the settings screen, you should see something like this:

You'll see that a second display is shown. Click on the grayed out display marked as "2". The window will change slightly to look like this:

You can then change the desktop resolution and color depth. Once you've done that, click your mouse on the "Extend my Windows desktop onto this monitor" to enable it. Remember that the resolution, color depth and refresh rates of each monitor adapter combination don't have to be the same. The window should look something like this now:
Click on OK and your second monitor should activate itself as an extension of the first:


You'll find that you can change the relative geometries of the two monitors by moving their respective boxes around in the Settings window.

Please reply to me if that doesnt help!!!

Throw it out the window. Acer sucks.

as it is not always sometimes only. this might be due to over oscillation in horz. stage.means more eht. it might be due to 1 power supply seems to be more then normal. 2 horizontal frequrncy not tunned properly if any preset is there. 3 loose contact in hor. section 4 some times it is due to connecting cable from monitor to computer.
