Before trying the following, as your notebook has problems running correctly, I'd strongly suggest making sure you have a back-up of all your personal files etc saved to an external device/media.
When done, try the following.
Shut down the notebook. Tap away at the esc key as you start the notebook to enter the Start-up Menu. Select the Bios option ( usually f10 ) and under the Advanced or Diagnostic tab you should find the facility to run tests on both the Hard Drive and Memory. Post back with the details of any error messages.
If both the above tests pass, try the following.
From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'. In to the prompt type the following command and hit enter.
sfc /scannow ( note that there is a space between sfc and the / )
Let the process complete, then type exit and hit enter.
Next, click the Start Menu, click Computer, left click Local Disc C once to highlight it, right click Local Disc C and select Properties. Click the Tools tab and then click the button to 'Check the Drive for Errors'. In the following window make sure both boxes are ticked and then click Start. Agree to schedule the check at the next system restart and then restart the notebook - this process can take several hours to complete before loading back into Windows.
