My computer switches on, but fails to load the operating system. Before this happened, it would crash frequently quoting an atisdva file or something like that for the error. What I would like to know is: has my hard disk failed completely and whether I should buy and install a new one?

Just like other computers, your Toshiba laptop may start failing to boot the operating system completely, or may fail to boot up at all. Boot problems are caused by virus infections and issues related to hardware and software. With the proper troubleshooting techniques, boot problems can be remedied to get the laptop into good working condition.
1. Perform initial hardware checks. Ensure that the laptop has enough battery life to boot up. Charge the laptop using its AC adapter and then try to boot the laptop again. If nothing happens, plug the AC adapter into another power outlet. If this does not help, check to see if external drives (flash drive, external hard drive, etc.) are connected into one of your USB ports. Unplug it from the laptop and press the laptop's power button. If the laptop powers on but fails to load the operating system, proceed to the next step.
2. Ensure that the hard disk is not disabled in the boot sequence in your BIOS. Otherwise, the laptop will fail to fully boot the operating system. Reboot the computer and press a key that will lead you to the BIOS page. Set your hard disk as your "first boot priority," or first in the "boot sequence." Note that the steps on loading the BIOS as well as navigating throughout the BIOS pages will depend on what brand of BIOS is installed in your laptop.
3. Choose boot to the "Last known good configuration" if you get an error page before the operating system boots up. If after choosing this option the computer reboots again, choose "Start Windows Normally," if this is in the list of options.
4. Consider repairing or reinstalling the operating system if the computer still fails to boot after the steps above. Repairing the operating system will retain your current data and settings. Reinstalling the operating system means reformatting or deleting all data in your computer and installing a fresh copy of the operating system.
I hope you find it very helpful. Best regards from fixya
When you install your operating system it will load your mouse and keyboard when you restart your computer.It will set up your hardware and install your drivers as it installs your operating system. Hope this helps--Ken
Usually when you see this come up on the black screen, it means that the hard drive is no longer being read by the computer. Either the hard drive has failed, or there is a bios setting in the interface that is not allowing the computer to talk to the drive. Check the bios settings first as far as devices the computer recognizes. If the hard drive does not show up in the BIOS, then either the interface has been disabled or the drive is dead. To enter the bios, hit F2 while the Toshiba splash screen is shown.
Chances are that it is a driver problem, try booting in safe mode by pressing f8 during the initial bot up process and selecting safe mode, with or without networking, if your systems goes in to windows then you have a drive issue, as safe mode loads with only the basic drivers needed to run windows, hope that helps
