Windows lost contact with hard drive?

Whilst perform a windows update my pc restarted it self, it was just as the update had finished downloading and about to start the initialisation when the screen turned blue and said that windows had lost all connection with the hard drive.

I then tried to run windows live onecare to check the system out and the same happened once it was downloaded.

Windows advised me to run CHKDSK /F to check for hard drive corruption which didn't say it had found any problems.

I've also ran norton, avg, spybot, ad-aware and super antispyware all of which have came up fine.

This happened this morning, I've also had problems with my yahoo toolbar not showing up all the buttons, every time the pc is restarted all the buttons except the yahoo home page disappear.(dont know if this is related to the above problem but thought it better to mention it just in case).

last week my sound drivers stopped working and it turned out to be due to norton, could this be causing the problems.

thanks in advance

:You havent "lost contact with the hard drive" if you can run all those programs.

Try this: Uninstall Norton in Add and Remove Programs in Control Panel.

After that is finished - Uninstall any programs that have the word Norton or Symantic in them.

Then - START %26gt; RUN %26gt; in the text box type MSCONFIG and click OK.

When the System Configuration Utility comes up go to the STARTUP TAB and untick everything that is listed (there is a Disable All Button) click OK

and let the computer reboot.

This last procedure will keep all those programs you unticked from starting when the PC starts.

IF all is working ok after that, Down load and install either AVG Free OR Avast Free for your Virus Program. You already have ad-aware and the others for spyware.

Norton is a RAM hog and tends to slow things down and is no longer in the top 5 virus programs.
