It's up to you - I will need it present to be able to properly fix the problem, since it is involved in a fair amount of the processing in the MGADiag report. All removing it does is hide the current problem, and potentially leave your system open to further unnoticed degredation.
As for the Event log, it appears to be only the log of errors from teh ATI Catalyst Conrol Center, not the Windows logs I need.
Open Event Viewer
In the left column, expand the Windows logs
Highlight the Application entry and right-click on it
Select 'Save All Events as...'
enter 'Application' in the File name box, and save the file to the Desktop
Repeat for the System log
Now close Event Viewer
On the desktop, highlight the two new files, and right-click - select 'Sent to..' > Compressed file
Accept the default - this will create the zip file on the desktop.
You can then attach the file you your reply.
