BSOD in random apps, without any event log enrty

Hi

My computer has started to randomly BSOD, without writing anything into the eventlog at the BSOD time.

It starts by some app hanging, could be browser (IE, Firefox, Chrome, happens with them all), or a small Windows pops up that f.eks. a taskbar app, like RoboForm, Listary, has crashed.
Then everything hangs, and NeXT BSOD :-(

Nothing obvious i Windows System eventlog, and nothing at the time of BSOD indication what goes on.

I have limited dmp analysis skills, so any help much appriciated.

minidump attached as per instruction.

Regards, Thomas
