Sorry for the delay, I've been traveling.
No events listed after November 1, 2009 that I saw - what happened that day?
No particular pattern of events that I could see either.
Have you scanned for viruses?
I'd suggest first running the Windows7 Upgrade Advisor: http://www.microsoft.com/downloads/d...displayLang=en
Then, if the problems continue, I'd suggest a clean install of Windows 7 (with no additional programs/drivers
installed - but all Windows Updates done).
