Also if your blue screen is showing a memory dump do the following:
Go to start | search (type in)
.dmp
Note the location of your
.dmp files.
If no
.dmp files check for
minidump.
Remember this location and the path that leads to it.
Then:
1) Download and install the
Debugging Tools from Microsoft
All you need do is download and install this. Make no attempt to start or run it.
2) Download and install this
debugwiz
This is a DOS based batch file that will command the above Microsoft Tools.
3) Open the Wiz & Browse to, or paste in the path to, your
.dmp file.
4) After the Wiz creates a Text document attach it back to this thread.
