System error password - Toshiba Qosmio DX730-101

I can only help with the system admin password (presumed windows). You will have to manufacture a "Password Reset Disk" on another PC or laptop (preferably running same OS - you will need your product key COA number). Instructions on MS website. Also - check your BIOS settings are OK when setting to boot on the password reset disk. That will be F1 or DEL probably on power up.Good Luck.

replace the ram or replace the adaptor.

What password do you mean, Is it a BIOS password or Windows?

ur prob in short???

that it is avery good day to me

If you have any other user account with admin rights then only you can change the password..else you have to reinstall the operating system.
If you have a different account with admin accounts.
go to start then in run type in cmd\
you will see a black window.

Then follow the below steps:

To change a user's password at the command prompt, log on as an administrator and type:
net user user_name * /domain When you are prompted to type a password for the user, type the new password, not the existing password. After you type the new password, the system prompts you to retype the password to confirm. The password is now changed.

Alternatively, you can type the following command:
net user user_name new_password
When you do so, the password changes without prompting you again. This command also enables you to change passwords in a batch file.

Non-administrators receive a "System error 5 has occurred. Access is denied" error message when they attempt to change the password.

This error indicates you hard disk drive is defective.

It seems its user name password issue

you'll need to contact Dell support for this one. they will be able to help you request a password that you can use to reset/clear the hard drive password. After it is reset, you may then set a new hard drive password if preferred. Be sure that you have the ownership information of the system in order to get help from Dell about this issue.
