Windows 7: force a memory dump

let me answer these in the order that I got them.
Anak: The Dump2Keys. It shows a table of values but does not tell you what key goes with what value.
Anak: My igdkmd64.sys driver is version 8.15.10.2279 so I am outside the range of bad ones.
panais: I have enabled driver verifier as per your instructions did a reboot, no BSOD yet.
Cluberti: I downloaded the notmyfault software and unzipped it. Not sure how this will help on a system that is totally hung and unresponsive but one more tool for the tool box.

Thank you all for your input and ideas.
I will let you know what happens if I have another hung system and I try to dump memory.

If the box is totally unresponsive, you have no choice but to use the keyboard (or NMI, but that's usually found mostly on servers). If you can find a PS/2 keyboard to attach temporarily, that would be very helpful.

Take a look at this thread ntdev member 7928's message 3 of 5 explains it in more detail.
If you need a deeper explanation cluberti would be the one to ask.

Good to hear your driver is okay.
