The loop on your Toshiba Satellite laptop refers to the computer not booting properly.

During the loop, the computer will try to boot the Windows operating system and keep restarting over and over again.

This is not a hardware issue with your Toshiba Satellite A106.

The issue resides in the startup files on your computer's hard drive.

You can fix this by running a repair tool that comes with your Windows operating system.

This repair tool will fix your startup disk and allow you to get your computer back up and running.

Insert your Windows 7 installation disc into your computer's optical drive.

Start your computer and wait for it to boot from the install disc.

Choose your language from the menu and then click the "Next" button.

Click "Repair your computer" from the menu.

Choose the operating system you are using and then click the "Next" button.

Click on the "Disable Automatic Restart On System Failure" button to disable the startup loop.

Click the "Startup Repair" tool from the menu and wait for the computer to fix your startup disk.

Wait for the computer to finish repairing your startup disk and then allow it to restart automatically.

Wait for the computer to boot correctly to your login screen.

Hope this helps

Startup issues are normally caused by recently installed software that has somehow corrupted critical files, or fault of the hard disk. In the case of the former, you may use startup repair to roll back to a restore point from before the problem occurred. In the case of the latter, you may run "chkdsk c: /f" from the command prompt (available after entering recovery). This will attempt to find and repair corrupt sectors of the disk.
