How to Use Ms Debugger to ResolveBlue Screen Errors Prepared By : Joeffrey Palatino of Team DOC All Stars
Overview • Windows Debugger is used to analyze crash and memory dump file whenever blue screen error happens. When blue screen errors occur it usually displays a STOP message identified by an 8-digit hexadecimal number such as STOP 0x00000050. When a stop message occurs it also creates a Memory.dmp file which will serve as a log to diagnose the cause of the blue screen and is more accurate than searching the STOP error code in Google.
What to do if there is no Memory.dmp file saved in the computer? • If the customer is getting always getting blue screen errors and you cant search for the dump file make sure the option to save it is enabled (which is usually enabled) by checking these steps: • 1.Right-click on My Computer • 2.Select Properties • 3.Select Advanced • 4.In the Start up and Recovery section, select Settings: this displays the Start up and Recovery dialog box • 5.In the Write debugging information selection make sure it is set to Kernel memory dump and the Dump file location is set to %SystemRoot%\MEMORY.DMP
