Yes you should have bought a Nolting,that's what I have..lol
I would see if you can get your $ back since it sounds like you have a "Lemon".
\Power supplies do not burn out unless you have a huge power surge and you are plugged into a back up battery pack.
I live in S Fl and we have the surges all the time.
You can get the back up battery at and Office Supply store. This is the one that you plug your cmptr in.
After this if the power supply blows,the machine should be returned and $ given back. in my opinion.
