I ran Memtest86 for several hours and no errors were found.
I checked the event viewer and the only critical errors I saw where me having to reboot my system. I did see alot of incidents in the Summary Page events that were listed as "information" The Source was always the ACEEVENTLOGSOURCE and they were things like this :
0000000006: 2010-03-20 23:14:48:907 Exception <AutoResetEvent exception on ICCC.Start>: Object reference not set to an instance of an object. Exception Called by: System.Runtime.Remoting.Messaging.StackBuilderSink::_PrivateProcessMessage processID:01452 threadID
