Hello! I have a problem when windows starts up. The windows logo shows(when booting), then the laptop displays a black screen that lasts for 36-37 seconds. I kept having this problem for 4-5 months, when i was running windows 7. I upgraded to windows 8 abut 3 weeks ago and the problem dissappeared, but it reappeared a week ago. I will attach a video file, ntbtlog and dxdiag info.

Thanks.
