The problem is that system restarts and after this it gives an error:
"A log off error has been occured"
I searched for this error and got one answer that i shld test my system's RAM. But I am not sure abt this solution. 2/3 days ago I installed a new printer. Is this new installation linked with this log off error?
can you check the event viewer to elaborate on the error.
start/control panel/ administrative tools/computer management/system tools/event viewer.
Look for anything with a yellow or red symbol and then double click. It should tell you the error and some infomation to help find the problem. It could be as simple as a printer service set up in your user account which needs moved to all users.
Like jbennet said, log of ,not log off ,and its doesn't say" has been occurred".
not picking on you English ,just trying to get the correct info so we can help ,now that we got it
