Hi I have a computer here for a friend and they said they get a BSOD every now and then and when they restart everything is fine. I was thinking ram prob so I ran a mem test from microsoft and it went for hours and no problems detected. I looked at the minidumps and It said a different file almost every time. The files were ipnat.sys, win32k.sys (in two different minidumps), hardware_disk, MpFirewall.sys. were all the different files that it identified as problematic. The computer is a Dell 9300 Laptop and other then the blue screen works well.
