The Computer turns on but none of the applications work. The touch pad on the laptop does not work and the start menu is not visible. Whenever I click on something it says, " the application has failed to start because the application is incorrect." Is there anything I can do besides a system restore?

When your mouse pad is not functioning, it's hard to get most anything done on your computer. The fortunate side to all this is that getting a mouse pad to work again on a laptop is not an overly complex procedure. A few troubleshooting techniques will quickly lead you on your way to productivity again.
Examine your mouse pad. Dirt and grime can affect performance and slow down mouse sensitivity, if not shut it down altogether. Make sure the surface of the track pad is clean and that there is nothing that has managed to get beneath it or around any trackball buttons that could affect the pressing and depressing of the component. Check to see if your mouse pad has been turned off. If the Fn (Function) button at the bottom left of the keyboard is pressed in conjunction with some other key on the keyboard it can result in the disabling of the mouse pad. To enable your mouse pad on a Windows PC go to the Control Menu. Under the Printers and Other Hardware option, click on Mouse. Then, click on the tab on the top of the pop-up menu that says Device Settings. The touch pad for your computer should come up as a selectable option. Click on it and you will see the option to enable your device, then click OK. If this does not work, proceed to the next Step . Check the manufacturer of your laptop (for example, Toshiba) and then navigate to their official website. Find an area for Software and Drivers, and move on to that area. Enter your laptop number (check your documentation/manuals and/or the bottom of the computer) and look through the drivers that are presented as a result of this number input. It could be that your mouse pad simply needs updated drivers. Find the driver that corresponds to your computer and mouse pad (for example, most Acer laptops use a Synaptics touch pad). Then, click on download. Once the drivers have downloaded, double click them to ensure they install, restart your laptop, and your mouse pad should be working again. Hope this helps.
Examine your keyboard to ensure your "Number Lock" key is not activated. This activation is indicated by the key being lit up. If the key is activated, press it to deactivate the lock. The number lock key will deactivate an entire segment of your keyboard
Start, click Run, and type regedit to open the Windows registry editor. In the registry, open the below folders.
HKEY_CURRENT_USER\ Control Panel\ Keyboard\ Within the keyboard folder, you should have a string value named "InitialKeyboardIndicators" with a value of 0, 1, or 2. Below is the explanation of each of these values.
0 = Num Lock is turned OFF after the logon. 1 = Disable Num Lock. 2 = Numlock is turned ON after the logon. Hope this helps.
Your laptop comes with a touch pad that acts as a mouse. Instead of connecting a mouse each time you want to use your laptop, you can use the touch pad that is integrated underneath the keyboard. This comes in handy when you are in a tight spot such as in a classroom or on an airplane. At times, you may need to unlock the laptop touch pad because someone who borrowed your laptop disabled it. It may also be locked due to a slight malfunction that you can easily fix by enabling the touch pad in your computer settings. Click the Windows "Start" button in the bottom-left corner of your desktop. Scroll up and click "Control Panel." Choose the "Mouse" icon or type "Mouse" in the field in the upper-right corner. Click the "Enter" button and then click the "Mouse" link. Press the "Hardware" tab or the tab to the right of it that specifies the type of touch pad you have. If you are under the "Hardware" tab, highlight the touch pad in the list of devices and click the "Enable" button. If you are under the touch pad tab, click the enable button. Click the "Apply" button and then click the "OK" button. Hope this helps.
