Please Help!

Hello everybody,
I'm new to this forum, but have been using mac for a long time and have never experienced anything like this. So, i have a brand new imac, 24" screen and have all the new software updated and all that, and last night, I noticed that my screen saver hot corner wasn't working, but all my other hot corners were working.

So, I decided to restart my computer, thinking that maybe this would do the trick. Well my computer wouldn't restart, so I took matters into my own hands and held down the power button for 6 secs to shut it down. Well when i turned my computer back on it opened set-up assistance(you get this when you first turn on a brand new computer and put in all your info).


So I thought this was pretty odd, but decided to enter in my info again and once i finished it took be back to the start again! Its in a loop and I can't get passed it! Should I call Mac support or has anyone gone through this? thanks

 

thanks, sorry to create a new thread!
