Question about Dell XPS 400 PC Desktop

1 Answer

Won't boot on startup

When I turn on the computer, it simply goes to a black screen and asks me for my system password. I do not know the password. I have removed the battery and waited several hours and replaced but still the same. I tried OPHcrack, but it is not booting from CD. I have also tried my XP installation disc and it did not work either. What is my next step?

The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.

System=intel Celeron D W3507 When I turn it on it goes straight to a black screen asking for a system password I've tried every password I know but I can't get in please help


If you don't see windows, then it's a BIOS password, and you would know if you set one. Unplug it and hit the power button, then touch metal, and pull the battery out for ten minutes. After you put the battery back in the motherboard, and plug it in you need to hit delete at start and enter the BIOS to set the time and date, then move over to exit and save changes.

I have a SYNET07526 Prroduct name Netbook. The problem I'm having is that it keeps asking for a password but I dont know it because I only got this thing yesterday, and I never gave it a password


In order to help you with your password problem, I need some details:
-Is the screen asking for password a black screen just at the start up of the computer?
-Is the screen asking for password just after the Windows started, asking for user and password?
-Has the computer available cd/dvd rom in order to use it as a boot device?
-What is the operating system you use on this computer, if the computer haas ever started? (Windows XP, Vista, Win 7)

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Ok try this, at boot up press F8, when the Menu comes up, choose Safe Mode, but this time instead of going to the desktop, choose System Restore, follow instructions, and when the Calender type window comes up, simply choose a time BEFORE, the time it went faulty. This should completely restore you to working again. As long as there are NO other problems.

CAN'T START UP COMPUTER DETECTS NO MOUSE OR KEYBOARD


The Blue Screen Your Are Talking About Its UNMOUNTABLE BOOT VOLUME and in case of blue screen mouse and keyboard are not detected as WINDOWS are not loading....

There Are 3 Ways To Resolve It But For All 3 Methods We Need The MICROSOFT WINDOWS XP OPERATING SYSTEM DISK...
1st Method Is WINDOWS RE-INSTALLATION. But In This Case All Your Data Would Be Gone..

2nd Method Is WINDOWS PARALLEL RE-INSTALLATION and in this method your data would be saved but you need to install the DRIVER'S SOFTWARE'S and other APPLICATIONS.

3rd Method Is The Easiest And I Prefer Which Is To Repair The Booting Sector.

To repair the volume, follow these steps: (10-15 Minutes)
  1. Start your computer by inserting the Windows startup disks or the MICROSOFT WINDOWS XP OPERATING SYSTEM DISK if your computer can start from the CD drive.
  2. When the Welcome to Setup screen appears, press R to select the repair option.
  3. If you have a dual-boot or multiple-boot computer, select the Windows installation that you want to access from the Recovery Console.
  4. Type the administrator password when you are prompted to do this.

    Note If no administrator password exists, press ENTER.
  5. At the command prompt, on the drive where Windows is installed, type chkdsk /p, and then press ENTER.
  6. It will ask u to overwrite the boot sector so press Y and overwrite the boot sector.
  7. type FIXBOOT and hit enter.
  8. When Everything Is done and new boot sector has been written successfully... type EXIT.
  9. Take Out Windows Disk and Restart Your System..
Some things that you should know before you try this solution loadTOCNode(4, 'resolution');
  • If the file system is damaged, you can use chkdsk /r command to repair the volume. However, if you use the chkdsk /r command, you may lose some data.
  • You will need the Windows startup disks or the Windows installation disk. If you do not have them, contact the computer manufacturer for help in obtaining the disks.
  • You will need the administrator password to complete the steps.
To repair the volume, follow these steps: 40-45 Minutes Complete File Repair
  1. Start your computer by inserting the Windows startup disks or the MICROSOFT WINDOWS XP OPERATING SYSTEM DISK if your computer can start from the CD drive.
  2. When the Welcome to Setup screen appears, press R to select the repair option.
  3. If you have a dual-boot or multiple-boot computer, select the Windows installation that you want to access from the Recovery Console.
  4. Type the administrator password when you are prompted to do this.

    Note If no administrator password exists, press ENTER.
  5. At the command prompt, on the drive where Windows is installed, type chkdsk /r, and then press ENTER.
  6. At the command prompt, type exit, and then press ENTER to restart your computer.
  7. After you repair the volume, check your hardware to isolate the cause of the file system damage.
If this procedure does not work, repeat it, but type fixboot instead of chkdsk /r in step 5.

Black enter password screen, but no password


I'm not sure if this will work but it may be that your system bios is asking for a password. If so, as you reboot the system, press F8 down until the system bios screen appears. Then page thru to see if the bios is asking for a system password. If so, you should be able to deactivate it thru the bios.

Hope this works.
