If your model Toshiba laptop has a Restore partition on thehard drive then follow these steps to restore your Toshiba to the Out of theBox condition.
1. Press and hold the 0 (zero) key and at the same time, tap the power buttononce to switch on
your notebook.
2. When the machine Starts beeping; release the 0 key.
3. When prompted by the warning screen; select Yes to continue with the systemrecovery.
4. Select Recovery of Factory Default Software; click Next.

7. Click Next to Start recovery.
8. Restart the Toshiba laptop when there restoration process finishes running.Follow the prompts that appear on the screen to set up the laptop's date, timeand language settings.

You very likely have a failing hard drive. Since the recovery system is also located on the same drive, you will have to obtain a new drive from toshiba with the recovery system on it or obtain a complete recovery set of dvd's. Since the system is not under warranty, then you could probably save some money by obtaining a suitable replacement (larger) hard drive from a reputable online source (like newegg.com) and then reinstall everything from the recovery set of DVD's you get from Toshiba. Recovery set should only cost about $30 or less. A new drive will run about $50 and up. The drive is actually pretty simple to replace. Since you will be replacing the drive, you should try and copy the important files (pics, music, etc) to a portable drive (hard drive, usb flash drive, etc.)

Here is a link to see what is involved in accessing your hard drive:

If your computer is new enough to have this option try this ... http://aps2.toshiba-tro.de/kb0/HTD9102IR0000R01.htm
Otherwise your computer doesn't have a "recovery partition" (basically a portion of your storage dedicated to being able to restore your computer) and you would require the factory recovery discs. If you have them, when you first turn the computer on and see the "Toshiba" screen press F12, which will allow you to select "CD/DVD", and do so with the first recovery disc inserted in your dvd drive.
If you don't have recovery discs you will need to make or order them, to make them look in your start menu for Toshiba Recovery disk creator and that will guide you through the steps.

Lines on the screen can be pretty much a hardware (LCD) issue. The first thing to do is to check if this vertical line is present outside of the Operating System so you need to go the BIOS screen of your L450.

How to go to BIOS? : Turn on your computer and start hitting the "del" key repeatedly until you see the BIOS screen.

From there, observe your screen and see if the vertical line is present. If it is, then you need to take your laptop to an authorized service provider (Toshiba) near you and have the LCD of your notebook replaced.

In case the line is not present in BIOS, then a display driver reinstallation using your Toshiba driver disc can resolve this problem. Ultimately, you may need to reinstall the entire Operating system if this still fails to resolve the problem.

All the best, and Thanks for using FixYa.

OS is corrupt...reinstall OS using the original Windows CD

You can try pressing and holding the zero key when you first power up the machine it may allow you to access the recovery partition on the laptop.
