I have tried that. I have done a search for this problem as well and haven't found any solution. I know a decent amount about pc's, but of why this is driving me so crazy. Will probably turn out to be something really simple, but its not the above mentioned solution.
Yeah i had a similar problem like that but my backgraound kept revert back to fill, everytime i shutdown. what did to fix this was, :C, user, your profile, appilcation data, roaming, microsoft, windows, themes, save your theme to your liking then drag it out as a shortcut, check read-only, uncheck when ever you want to modify. Also is you have asus uninstall your power4gear program.
