Over the past ten days on my Win7-Pro PC, I have received the following error message:

"System event notification service" not found. What problem am I likely experiencing or likely to experience? The issue may have to do with Bitdefender as the software doesn't seem to be loading on system startup although everything else seems to have loaded properly. After 15 minutes or so, Bitdefender then seems to have loaded and is working properly.

On the other hand, could this be a sign of a failing or about to fail hard drive? I'm really confused about what may be going on. I do, however, make daily system backups as I don't know what else to do.

Also, where do I find the system event log files? I can't seem to locate them. Thanks, in advance, for any advice or suggestions.
