Well my dad has a pretty old machine( 466mhz celeron, 196 ram, voodoo 3 3000), and he saw fit to upgrade it. He put in a new card, radeon 64md ddr (thats what its called!), and now the display wont shot up. WHen u turn on the machine, it gives a slightly long beep followed by 2 more beeps. Anyone have an idea whats going on with that?
