I have a older dell p4 with windows xp. Use to work well now for about a year this is what happens. On startup it runs through bios setup, reads floppy, reads cd reads hd. Then pops "hit del to continue" if i do the machien works ok. I have unhooked floppy, unhooked cd, tried different cd, replaced cmos battery, it this a hard drive problem or a mother board problem.
