"logon process has failed to create the security options dialog"
I don't have time to type the issue i have but computer randomly freezes and I get this error when I try ctl alt dlt. If you do a google search it seems that I am not the only one having this problem.

Do you have Trend Micro Internet Security installed?
That kind of error may appear with the above program installed....
Can you post full error message?
Does it say anything about I/O error?
Go to your hard drive manufacturer web site, and download free diagnostic tool. You may have hard drive problem.
