So you connected a projector to the VGA port on the back of the computer, right? Did it work?
Now you have the regular display connected to the VGA port but are not getting any picture, right?

Do you see anything on the display when you first turn on the computer? If yes then it sounds like it may be a resolution problem and your monitor can't display it. Try this.

Boot so the Advanced Boot Options menu (aka Safe Mode menu) by pressing F8 during boot when you see the Dell logo. Tap every second or so until the menu appears.

Select Enable Low Resolution Video (640 x 480). If it boots okay and you have output to the display, right click on the Desktop and select screen Resolution. Set it to the correct values for your display.

Yes a projector was connected but it did not work.
Monitor was reconnected but no output once the computer is booted up.
There is output while the computer is booting up ,can see windows 7 logo etc,then it disappears.
Have tried booting in safe mode and selecting 640x480 but it does`nt help, the display disappears once it boots up.

You could try doing a System Restore from a Win 7 install DVD or flash drive. See here: My link

Scroll down to:

Option TWO:
Through System Recovery Options at Boot

Note: This will allow you to restore Windows 7 to a earlier restore point with a Windows 7 installation disc from the System Recovery Options screen at bootup. This can be handy if you cannot startup Windows 7.

If you do not have a Windows 7 installation DVD, or it's not up to the Service Pack level currently installed, you can download a legal copy with SP1 integrated from here:

Windows 7 Direct Download Links

Make sure you get the same version you have, Home Premium, Pro or Ultimate and 32 or 64 bit. Note that Basic or Starter is not available.

I recommend using ImgBurn at 4X speed (or the slowest available) to create the DVD from the downloaded .iso file. Just be careful during the install not to accidentally install some of the bundled junk that comes with it. Always take The Custom Install option.

You can do this on any computer capable of burning a DVD.

YOU MUST HAVE A VALID KEY TO INSTALL THIS .ISO.

The one on the COA sticker on your computer will work.

You can also create a bootable USB Flash drive (4GB or larger) to install Windows 7 from.

• Download and run Universal USB Installer Easy as 1 2 3
• Select Windows 7 from the first drop down list, all the way to the bottom
• Select the downloaded Windows 7 iso file
• Select your USB flash drive
• Click Create
