My daughter's laptop goes to the screen that says Windows did not start last time & then offers the variuos options eg safe mode, last known good configuration. etc. Whichever I choose - it goes to a Blue screen which then vanishes so quickly I can't read it- the only phrase I've managed to catch is something nearthe end which says something about memeory dump.
Then it goes back to the page mentioned above- and the whole thing happens all over again.
