Help with pc admin properties

[SIRCOOKS]

Im witnessing a serious problem with my comp. I dont have the ability to install programs. And its affecting me downloading thins becuase it wont allow me to write to my c:// drive. Programs are now telling me im not the admin, i need to log on with admin credentials. Ha san yone ever encountered this before?

But to work im perfect. It always telling me "files are not online available", and "network connection is encountering problems', i always get this at home and its frustrating.

I have mcafee 8.5i installed, driver updater pro, everything else are typical programs...i dont know what to do.....please advise

Are you a admin on this PC?
If you are, log in as the admin in (Safe Mode)
then remove then re-add youself as admin.

let me know what happens
