Need drivers for m140 dell laptop base system device, video controller and video controller vga campatible

A base system device is any hardware device pre-installed on your laptop, such as a CD-rom drive, a USB port, an Ethernet port, video card, etc. These devices all require pre-installed drivers that were supplied by Dell with the factory setup. The most common problem is to have one of these driver files corrupted or deleted by accident. To solve a base system device driver problem, you have to go into Windows Device Manager (Look in Control Panel), and look for devices listed with yellow question marks or other indications that they have a missing driver. You either then go to the Dell support site for your laptop model, or the driver disk you may have gotten with your laptop, and reinstall the needed driver.

Download drivermagican from it's site.

Need driver and bios updates?

Always get your drivers and specific software from the manufacturer of your Laptop, Notebook or Desktop. They are usually free of charge.

If you were to log on to the manufacturer's web site, usually one is able to download if available, by model number, All available Driver downloads as required.

If the driver is not available, perhaps your manufacturer does not support the OS you are installing.

This is the best way of ensuring up to date drivers for your system and they are free of charge!

I hope this helps.

try other lan drivers..

go to device manager , click on networks
uninstall the wireless network card , go to support.dell.com
update the latest wireless drivers for your wan card , restart the system it will start working

Try to manually update the drivers.
Go to Settings/Control Panel/System
Hardware tab
Then Device Manager
Click on one and update.
Let the OS search the CD with the drivers.
(You may have to navigate to the correct directory)

If this fails you will have to go to the DELL website and download the drivers for your machine.

Hope this helps!
Good luck!

Make sure any programs that consist of sound for example " Soundman" is running this can cause a conflict with your audio. Check for updates if you can

hey man!..check the physical volume control down in your laptop..or Fn+ volume control key..if not available..or still same problem..try to re install the sound driver...

Go to "Device Manager" and look if any yellow or red alerts are being displayed next to any devices. To access the "Device Manager" go to the 'Control Panel", "Administrative Tools", "Computer Management" and select "Device Manager" located in the left side column.
If there is an alert, double click on that device to determine the problem, i.e.… device not configured, cannot start this device, etc…
It sounds like all your software drivers got blown away or can’t load. If that’s the case, try running diagnostics. Press and hold the <Fn> key while powering the system on. This will initiate a diagnostic routine to check your hardware.
