Thanks, let's see if manually initiating a crash via the keyboard will do us any good.
You need to first setup your computer to produce kernel memory dumps (instead of minidumps): http://www.mcci.com/mcci-v5/support/howtos2.html
Then you will need to run the Registry Editor (regedit.exe) with administrator privileges and make the following changes. (Of course you should create a system restore point prior to this.)
With USB keyboards, you must enable the keyboard-initiated crash in the registry. In the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\kbdhid\Parameters, create a value named CrashOnCtrlScroll, and set it equal to a REG_DWORD value of 0x01.
Reboot your computer and the next time your computer hangs, hold down the rightmost
CTRL key on your keyboard, and press SCROLL LOCK twice. This should force the hung system to crash generating a nice, juicy dump of what was going on in kernel mode. After the system reboots do the following to send me the dump file:
• Press and hold the Windows Key + R on your keyboard at the same time.
• In the Run box, type in %WinDir%
and hit Enter
on your keyboard.
• Find the file MEMORY.DMP
and copy/paste it on to your Desktop.
• Zip up MEMORY.DMP (use .ZIP please!!!)
and upload it to a trustworthy
file-sharing service (like DropBox, Google Drive, OneDrive, etc.)
Don't be surprised that the system doesn't blue screen though. (I don't have time to get into why this is the case; best simple explanation is that it depends on how "low-level" the hang is...)
