First of all, Im No computer guy, I saw this problem and thought i could fix
it, OOH Boy !!, was i wrong. when the recurring window kept popping up, I
went Ctr Alt Del and brought up Task Manager, went to applications, it was
the only one running, right clicked,and told it to < Go to Process>

It told me it was the CSRSS.exe file, SO I, did a search, found there was
three of them and physically Deleted them all, OOOH MY GODD!!!, Now the
computer will not start up at all and continually tells me that =
