screen,the green light comes on,the dvd rom tries to boot,the floppy also
tries to boot,we know the monitor works because we tried it on another system,
how can we tell if the onboard video adapter is bad?and what else can i do to
get it to boot to the operating system,also there are no beeps to confirm
what is wrong.help....
