Thanks for the swift response, the only event relating to today when I first ran generate a report is Information level:
Event ID: 1904
I dont seem to have any critical errors relating to this issue.
Interestingly when I ran performance monitor I also had the error:
Unable to add these counters:
\Memory\% Committed Bytes In Use
\PhysicalDisk(*)\Avg. Disk Queue Length
\Network Interface(*)\Bytes Total/sec"
I fixed this issue with the following link: PerfMon problems - Unable to Add Counters
I notice that although the report is still not generated the html file size has gone from as little as 900kb to over 3MB since running this fix for peformance monitor. Guessing something is still corrupted somewhere, any thoughts on how to proceed, I have also ran a system file checker and came back clean
