Why aren't any system integrities being showing in the event viewer in audit?

[Windows Central Question]

No system integrity checks are being shown in the event viewer in audit success.

I had noticed I was getting audit failures 5061 and was able to narrow it down to Nvidia streaming service. I stopped the service for that but now I don't even see success audits for system integrity. I am a little concerned and going bonkers over this. Using Windows 7 64bit. Ran malware bytes, Norton and Sfc scan and everything came back normal. I've checked my other Windows 7 computers and they all have system integrity checks from the moment the system boots. Am I going crazy or what?

Thanks!
