Hi,
For the event error, please refer to this article:
http://technet.microsoft.com/en-us/library/cc727052(WS.10).aspx
From this article, it is caused because there is too much event logs so it may not directly related to your current issue.
Thus currently we still have a performance issue. Please first try to disable third party programs with Clean Boot mode to see if same issue persists.
Perform a clean startup to determine whether background programs are interfering with your game or program
