I don’t know either but I will give some more background info:

I uninstalled some time before my first bluescreen Iolo System Mechanic.
After that I got several times a scandisk before Windows was starting up, but the scandisk never found a error.
I did a complete scandisk with surfacescan (no errors) and after that I did a defragmentation.
Since that moment the scandisk problem is solved and my blue screen problem too.

I didn’t mention that before because I dont’s saw a link (sorry :'().

Maybe it fixed something. ???

The truth is that both problems are solved now.
And I’m verry happy now :smiley:
