Hi all, I hope Im posting this in the right section. I would need help to understand why my laptop crashed. I read the dmp file online and the data is: Crash Dump Analysis provided by OSR Open Systems Resources, Inc. Online Crash Dump Analysis Service See osronline.com for more information Windows 8 Kernel Version 10240 MP (4 procs) Free x64 Product: WinNt, suite: TerminalServer SingleUserTS Built by: 10240.16545.amd64fre.th1.150930-1750 Machine Name: Kernel base = 0xfffff801`76807000 PsLoadedModuleList = 0xfffff801`76b2c070 Debug session time: Thu Oct 29 02:27:16.600 2015 (UTC - 4:00) System Uptime: 0 days 9:16:46.309 ******************************************************************************* * * * Bugcheck Analysis * * * ******************************************************************************* SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e) This is a very common bugcheck. Usually the exception address pinpoints the driver/function that caused the problem. Always note this address as well as the link date of the driver/image that contains this address. Some common problems are exception code 0x80000003. This means a hard coded breakpoint or assertion was hit, but this system was booted /NODEBUG. This is not supposed to happen as developers should never have hardcoded breakpoints in retail code, but ... If this happens, make sure a debugger gets connected, and the system is booted /DEBUG. This will let us see why this breakpoint is happening.
