Vista Desktop Not Loading

Hi, Im hoping someone can help me.

My laptop has Vista Home Premium, when i turn it on, the Toshiba screen appears, then the Windows welcome screen, enter my password, i then just get a black screen (no destop or toolbar loads) but the drive light is flashing and it sounds like it is doing something. When i press the shift button 5 times, the sticky message appears and thats all it does. Cannot get task manager. I have tried doing a system restore, that doesnt solve the issue. I tried loading in safe mode and its the same problem.

I tried to crash and start the machine again and it asks for a administrator password which i dont know.

Im hoping its not serious, what could i do?
Thanks in advance for any help!

Welcome
Why dont you know the password? Aren't you the administrator. Did you make any changes etc. Download anything. Go to sites that you should not visit. It can be a virus.

This should help
If you create a recovery DVD, you may be able to boot to recovery options
Create Recovery DVD

The Vista recovery disk is used to boot Vista when it won't boot - to run Startup Repair, System Restore, access a Command Line, Recover using a Vista Backup Image, etc.
System Recovery Options

If Vista will not start now, boot the Recovery CD to run Startup Repair which automates System Restore as well as numerous other tests including System File Checker which can repair system files which are not corrupted beyond repair.

If Vista still will not start, try booting into Safe Mode to run sfc /scannow to repair System files.

Below is a bulletin distributed by MS to explain the start up procedure when Windows will not boot.

• Startup Repair. Startup Repair is a Windows recovery tool that can fix certain problems, such as missing or damaged system files, that might prevent Windows from starting. Startup Repair is located on the System Recovery Options menu, which is on the Windows Vista installation disc. If your computer has preinstalled recovery options, it might also be stored on your computer's hard disk. For more information, see Startup Repair: frequently asked questions and What are the system recovery options in Windows Vista? If your computer does not include Startup Repair, your computer manufacturer might have customized or replaced the tool. Check the information that came with your computer or go to the manufacturer's website.
• Change restart settings in safe mode. If your computer is stuck in a loop where Windows fails, attempts to restart, and then fails again repeatedly, restart your computer in safe mode and select the Disable automatic restart on system failure checkbox. For more information, see Advanced startup options (including safe mode).
• Reinstall. If no other options have solved the problem, and you are sure that your computer's hardware is functioning normally, you might need to reinstall Windows. A custom (clean) installation of Windows will permanently delete all of the files on your computer and reinstall Windows, so only use this option if all other recovery options have been unsuccessful. After the installation, you will need to reinstall your programs and restore your files from backup copies. For more information, see Installing and reinstalling Windows**.
