My 7 years old kid playing free flash games and clicking at random, my wife clicking some buttons when the computer failed to start the first time, and then powering it off "while it was doing something" ....
So ... I was hopping to repair it without a fresh windows installation, but it seems it is more complicated than it seems.
Thanks, and I am still waiting for a solution `till I get at the office tomorrow where I keep my windows cd.
