It seems that everyone is on about the Software,
You went on holiday, Vacation and or away from your place of stay,
Think about these options, something has come loose ie: memory,
something has not liked the fact you had a Vacation,
Your Hard Drive is failing (Is it making a Clicking noise or even come loose)
Try doing a system Restore from the day you left, if its not changed then its internal.
Always think outside the Box, well in your case Inside.
