I have a Toshibia notebook which came with Vista. YUCK!
I installed win 7 ultimate and it's been a couple years since trouble started.
Three out of four times it wants to repair itself at startup.
Sometimes I have option to repair or start normally. Sometimes normally works!!!
I have replaced hard drive and reinstalled Windows. Same problem.
I suspect a windows update is culprit.
I have no experience using log files.
Guidance much appreciated.
