my old computer's cpu died and it was still under warranty so i went ahead and got a new one from AMD. the old computer got replaced with a new motherboard & cpu .. and i'm trying to build a new system with the old motherboard that had the old AMD cpu on it which died. the problem now is that during the bootup process where it shows what cpu you have and the memory test and you have the option to press DEL to enter the BIOS setup, my keyboard does not work & it freezes on that screen after the memory test. i kno the keyboard functions as it lights up prior to the bootup process, but once frozen on that screen it ceases to function (can't press caplock or num lock or scroll lock). oddly enough, the screen shows that the cpu is an AMD ATHLON XP 1800+, but what is really in there is an AMD ATHLON XP 2400+. what could be the problem? did the motherboard just die as well with the old cpu?
