Hi first time user. I received this message as I booted up "Alert - Previous fan failure. Press F1 to continue." I called Dell support and found out I was out of warrenty but he said go to a local store and have the power supply replaced. I took it in and they replaced the fan - not the power supply and said it would now be OK. The alert keeps coming on and I have to press F1 to get to my desk top. My questions are - Is replacing only the fan the right thing to do? and How do I get rid of the alert if it is the right thing to do?

Thanks in advance
