Anyone understand minidumps?

[Mags]

I was working away quite happily, then Windows closed down and restarted itself and a 'Serious Error' popped up and told me where the minidump was. And this screen came up - http://wer.microsoft.com/responses/R...2-72369eb44585

I don't know how to open minidumps, does anyone? I'll attach it (now found out I can't attach files like that)

Trying to think what I did that may have caused it? I needed a program to amend some audio files, so downloaded two shareware trials - Internet Explorer box said don't .. so I did !! They didn't work, but maybe that was it? And I don't know what they were, cos I uninstalled and deleted the downloads.

Ran Adaware - everything ok, but from one tracking cookie.
Ran Norton Scan - clean.
Also restored PC to yesterday's Restore Point.

Gotta dash...
