HERE is the step-by-step from ASUS on how to do the system recovery.
follow it and you should be fine.
And, yes, it will take it back to "factory fresh"....you will lose all data,so, remember to backup teh files you want to keep as this will totally erase/overwrite everything on your C: drive.
Right, recovery done, factory settings restored.... and i'm STILL getting 'not genuine' notifications every 10 minutes!
Reinstalled Kaspersky, MWB & Spybot, none of which are finding anything. Spybot STILL isn't allowing me administrator privileges either so I can't Immunize.
What to do?
its a quite good discussions
