I had a similar experience yesterday.
Last thing before shutdown Monday, avast! updated VDF.
Tuesday, tried a normal start twice, got same BSOD screen as you describe on both attempts, no MEMORY.DMP generated.
Third attempted start was successful and immediately, another VDF update was applied. No further problems. (I didn’t think to keep track of update version numbers.)
Wednesday (today) updated to 110921-0 at startup. All seems OK.
