This morning, my computer was turned off. I usually leave it on at night, so this must have been a crash. Starting the computer confirmed this: Windows did not shut down normally.
Later today, I went downstairs for dinner. When I got back about 30 minutes later, the computer was turned off again. And once again: Windows did not shut down normally.
The problem is that windows isn't generating any dumps. I went and checked advanced settings and it's set to do a kernel dump, but the file isn't there.
I then checked for all files ending in .DMP, which turned up nothing.
The Event Viewer isn't helping either. It just says that at a certain time, Windows was shut down in a bad way... no details.
So, I need to find a way to turn on the creation of a mini-dump, if I'm ever going to be able to analyze this. Given that the advanced settings are set to make the dump, but they're not doing it, what else can I do?
Edit: my machine is a HP Pavilion dv7 laptop. Running Windows 7 Home Premium 64-bit SP1.
