My computer was working well. The last last thing i remembered is that the computer downloaded WINDOWS AUTOMATIC UPDATES. I dont know if it was installed properly by my little sister when she turned it off. Next day after, when we turn the PC on, the monitor will only show streaks and dots of different colors. What is possibly damaged here?

Re: ONLY STREAKS OF COLORS when TURNING ON!
If it is doing it to the start up screen(hp) it is probably the display chip on the motherboard (you may be able to clear this up by removing the battery from the motherboard and clearing bios( connecting the two pins on the motherboard.
But before you do this check your video output with another tv monitor
The problem is the update you downloaded someone mixed with your graphic chip.. causeing it to only display dots and lines. the hp logo with the back round is the start up page. here are 2 ideas you might wanna try.
1. if your graphics car is in a AGP or PCI, pull it out and try useing the default card build in the computer.. if it is the default go out and bye a cheap graphics card and see if that works.. if not return it and get your money back.
2. try useing a diffrent moniter.. your moniter might of blown out. if that still dont fix it you might need to contact HP or the moniters manufactuer.

Forgot Windows XP password? The first thing which you check is whether you forgot windows xp login password or not. When we install Windows, it automatically creates an account "Administrator" and sets its password to blank. So if you have forgot your user account password then try this: Start system and when you See Windows Welcome screen / Login screen, press ctrl+alt+del keys Twice and it'll show Classic Login box. Now type "Administrator" (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows. Now you can reset your account password from "Control Panel -> User Accounts". Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen. Windows XP and further versions also provide another method to recover forgotten Password by using "Reset Disk". If you created a Password Reset Disk in past, you can use that disk to reset the password. Or try free program called Ophcrack or Windows Password Recovery Tool 3.0.
looks like it's stuck in a startup loop, can you boot from a windows cd into repair console (press R to repair with xp, choose repair my computer with vista or 7) ?
if so, type the command fixboot and after that fixmbr, if it still doen't work, try the chkdsk /F /R command. if that doesn't work, try booting in hirens boot cd (download v13 and burn it to a cd rom) if still no success, you need to reinstall windows, if that doesn't work, replace the harddisk and reinstall.
Go to Start, Control Panel, then to Programs and Settings. Right click on top of the columns (The ones that have the program names, etc) is light blue on to says Name, Publisher, etc. Choose the selection MORE... then put a check on "Last Used On" and this will show you the last time you used the program and you can then determine which ones you dont use.
I've tried doing a search online using the details you gave and I came up with the following page that you might want to check out: http://www.user-guides.co.uk/download/dell/delllatitude/dell-latitude-d600-original-recovery-disk.html What operating system are you using on your dell laptop? If your operating system is corrupted it sounds to me like you may need to reinstall windows. May I ask when you experienced this problem? When your system was working fine what was the last thing you did prior to your system not being able to boot? Could you have installed some kind of incompatible hardware or software? When you turn your computer on you could try pressing f8 or f12 and this will take you to the Advanced Options Menu. From here you can try safe mode, last known good configuration, reboot etc. I don't know if you have tried these things! If you go into safe mode and this works this will load windows with a very basic configuration. Once in windows you can unistall a piece of software if this is the last thing you did that caused your system to fail in the boot process. You also might try getting in touch with Dell. Sorry, not much help otherwise, good luck with your situation. Andrew
Choose safe mode and see if you can get into it. If you can then go into system restore and choose the last date that you remember the computer working properly.
At this point the computer will restore the computer back to the earliest date that it was working properly.
Once you do this the computer will reboot and it should go back into windows normally and work just fine. If for some reason it doesn't then windows is corrupted and you'll need to wipe out the hard drive and restore the computer back to factory defaults.
What have you tried so far, specifically? From the description provided I would try two things. First, I would check on Dell's support site to see if there's a newer driver available for your sound card, as they update them fairly regularly in most cases.
Assuming you have Windows XP, this link should get you to their audio driver section for your machine:
Do you remember making any system changes from the time the sound worked last until it stopped? Maybe something was installed that caused a conflict with your sound card. Does everything appear ok in the Device Manager? (Start -> Control Panel -> System -> Hardware -> Device Manager) Nothing shows up with a red X or a yellow exclamation point?
