Maybe a virus or infection has hijacked the keyboard. Try booting into Safe Mode and see if it works. Also while in safe mode download and install MalwareBytes and run a Quick Scan.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode With Networking option (this will give you internet connectivity) and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. Open your internet browser, then download and install MalwareBytes and run a Quick Scan.



Go to www.google.com and in the search box type: "Download cnet Malwarebytes" (without the quotes). Download and install malwarebytes from the sites download.cnet/malwarebytes. When the site opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version or Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine.

If after the above steps you still have the problem try downloading and reinstalling the touchpad driver.



Get online and got to www.google.com In the google search box type: "Toshiba Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operating system when requested. Download and install the Touchpad drivers.



If the issue still exists try Rolling your System back to a date and time before the keyboard started acting up by running System Restore.




Click Start/Programs/Accessories/System Tools/System Restore. Select a Restore Point (date and time) that is before you started having problems. System Restore does not delete you data, documents music, pictures, videos or programs (unless the program was installed after the restore point you selected).

System Recovery loses all your data, documents, music, pictures, videos and programs. It sets your system back to the time you first purchased it.

Windows internet explorer not working


Hello,

was explorer working perfectly on your computer previously? If yes, you can try system restore.

System restore can help to back date your computer to the time when explorer was working.

Start > All programs > Accessories > System tools > System restore.

Read and follow instructions. System will restart during the restore process.....

After that try again and observe if explorer will function/work properly/normally.

Please let me know if this doesn't solve your problem so that I can help you further.

Regards.

    I need assistance running the restore program I have a virus on my computer that is keeping my internet provider from cleaning computer


    You didn't list your operating system but if its XP here is how to access "system restore".

    Start / All Programs / Accessories / System Tools and then system restore.
    Follow the prompts, choose a point to restore, and then the machine will reboot. Please make sure that during the restart not to power off.
    Sometimes going back to a prior build will work and sometimes it won't.
    If, after the reboot the restore failed you could try turning "system restore" off and then reboot and after the restart turn "system restore" back on. To do this right click on "My Computer", click on properties. In the new window click on the "System restore" tab.

    Hope this helps.

    Toshiba A105-touchpad mouse intermintent problem


    If you know where the touchpad/mouse driver is located on a recovery disk, I would 'delete' the mouse via the control Panel, reboot and see if Win will reinstall the driver from the restore partition or, ask for a disk as a source and you have to know where that driver is on the optical disk. I would locate the drivers on your recovery disks before you delete the current device.
    Alternately, you might check Toshiba's support section for a touchpad driver for your OS and system and burn it onto a removable disk or thumb drive that you give to Win as a destination if asked.
