I hope you can get this all back under control before anyone concludes something as drastic as a Windows reinstall. Deleting things in the registry without a clear plan or understanding of the result can lead to trouble.
I could hope you didn't install any other software at this point, and you could roll back the system to a checkpoint before you made those changes.
The other advice I saw required simply re-installing the Suite 3 and hoping it would put things back in order.
What I know about Suite 3 is this: you're best to uninstall it from Programs and Features, or from the ASUS "uninstall" in the start menu. But after you do that, you will want to run a "cleaner" program made available at the ROG forums for that purpose -- if you can get it. You don't need the fan-control software, but you CAN work within an ASUS BIOS to get the same result. The software isn't needed; you can use a different monitoring program like HWInfo64. you don't need the "turbo" and other parts if you accept the inconvenience of getting into BIOS to tweak and overclock -- which admits less uncertainty or confusion.
I wouldn't hesitate to tell an enthusiast-ASUS user to install the bundled Suite for use while building the system -- PROVIDED that there's no evidence among other users (in forums, etc.) that UNINSTALLING the software needs that sort of special attention -- a "cleaner" for instance.
