I have had this problem for a long time now and it's drivig me crazy. I have reinstalled windows but without luck. It's mostly a error with Event 1003 and category 102 and with message PAGE FAULT IN NONPAGE AREA and error code 0000000000000050... but sometimes it is driver irql not less or equal and sometimes it mentions something with ntfs.sys or win32k.sys. Lately I think the random reboots have occurd pretty often when I install stuff but i'm not sure it can happen at any moment. I hope someone can help me to figure out what the problem is. I have uploaded my minidumps
