My dell inspiron 1720 does not turn off automatic with windows XP

If you are running Windows 7, if you type in the wrong password once, it normally says reset password... below the box for the password. Insert a removable disk (such as USB, floppy disk, etc.)
and follow the prompts.

you might need a usb to speaker adapterhttp://www.ebay.com.au/itm/USB-2-0-MIC-Speaker-5-1-Audio-Sound-Card-Adapter-/120645945426?pt=AU_Laptop_Accessories&hash=item1c170f0852

hope this help

Make use of some antivirus! Or it may because that your internal memory is full...

What do you mean by "Back Light"? There should be drivers for everything at your manufacturer's website.

Make sure you DO NOT plug in your lap top to the power out let. This could cause a shock.
You see the Dell media direct, means your CMOS is OK.
But if Windows is not loading means the spill could have damaged your hard drive. I would strongly suggest you take it to a shop where they repair laptops.
This way you may have to replace your hard drive, but save your note book.

If you can see the vertical lines during POST, try to check the vertical lines in BIOS. If the vertical lines are there in BIOS, the only thing you can do is to replace your LCD screen.

Is it black all the time? From when you start your computer to when you turn it off?

Sounds like the backlight is bad.

you can have the webcam workin for only ne application at a point in time also check to see that you have activated the webcam access on the other applications and this time try with the windows firewall and other firewalls deactivated

COPY UR IMP DATA O OTHER DRIVES AND FORMAT UR WINDOWS.
BEST SOLUTION.
AND DONT INSTALL UPDATES
