Why when i try to shut down or restart sometimes appears ...memory could not be read?. And it stops the process.
Thank You.

This is not much to go on Do you have Java installed?

No, I don´t have installed java

Mouse over the Windows flag, click on "Search" type MSconfig in the search box and click to search. Click on MSconfig and in the new window on the Services tab, click to put a tick in the box "Hide all Microsoft services" and then on "disable all" then click on apply, then OK. Finaly in the new window on restart and see if this fixes your problem

As your problem is intermittent you may have to restart a few times to see if the above helps.

If it helps you can then enable the services one at a time to find the culprit.

To get back to a normal boot. "after the step Hide all Microsoft services" just simply select enable all or put a tick back in each box and restart the PC

Thank you very much, I´ll try, and then tell you the results

I did it, but my problem is when I clic to restart or shut down, not when is startting

Yes I know did it make a difference?

Ok, thank you
