Does the system boot normally, but the setup screen is the first screen displayed when us press DEL or F2. In my case, the key is F2.
The Dell boot normally, and work well. I already replaced the memories, to teste, but, if I press F2 and it go to the setup screen the screen remained freeze and the setup screen has seven pages and the ALT+P to change pages don't work and all the menu option within the first page too.

I ask you: What are the other options?
