Warning CPU has been changed. I needed to put a new power supply in my computer. Now it does come back up but with this warning... Warning! CPU has been changed. Please re-enter CPU settings in the CMOS setup and remember to save before quit! If I click on F1 it brings me to my desktop but says I need to restore desktop, but it will not allow me to. I have tried everything to get into the setup, but have no idea how. Any ideas? I am not a pro at this stuff, and simply do not understand it. I will try anything you say, but to please try to be as clear as possible for me. I would greatly appreciate that. Thank you.
