I'm writing here because I read and tried many solutions to fix this problem on my windows 8 but none of them has worked up to now. I still launched a file system check with sfc /scannow
but it was useless.
Then I've tried to go Computer->properties-> adavanced properties->startup and recovery-> and I've disabled "Automatic reboot" and selected "memory dump Comleted" in wiriting information debug.
Nothing again.
How can I fix this annoying problem? I don't know windows very much, if you can tell me what and where I have to check (logs for example) it would be very useful for me. My pc (Sony Vaio sve1513q1esi) was native with windows 8 so there shouldn't be problems with hardware drivers.
Usually I work on Ubuntu but unfortunately sometimes I must use windows too.
