My computer ran with L6 being idle this afternoon, I was away in "real life". When I came back, I saw it had crashed. No Crash Log, nothing in the error log, too - last entry from yesterday (indexer had run yesterday for the last time, too - successful completed ).
Logos.log stopped at 1:59 pm, according to Windows event log, the crash occured at 2:48 p.m.- first crashed .NET, then Logos.
