So I just put together a new pc P4 dual core 2.88 ghz 1gb ddr ram stick, 1 256mb ddr ram stick biostar p4800-m7 mainboard IDE 0: 250 gb HD (m), 120 gb HD(s) IDE 1: Lite-on CD/RW (m), 80 gb HD (s) ATI 9800xt M-Audio audiopile 192 so i install everything, i boot; everything is fine; all the drives show up; it reads my cpu correctly; so i instert my windows XP pro disk; and nothing. It hangs on a black screen. no "booting from cd"; or anything I can go into my bios, everything shows up fine.. normally when i build a PC and put the windows disk in, it gives me the option of booting from the cd is i press something. but now nothing. any help?
