Ok so I am building my parents a computer out of spare parts. Mostly mine, and I know everything works. When I first plugged it all in, I got three beeps, which lead me to think it was either A) The fact that I didn't have a keyboard plugged in B) Faulty memory or C) The video card So I fixed two of those at once. I plugged in a PS/2 keyboard, and took out all the RAM, and then put one back in. It then started up. I must note, I have no CD/DVD Drive or Floppy, all mine are sitting in the back corner of a storage room, so yeah screw that. Also, the HDD is brand new, so it doesn't have any formatting. It no longer beeps, but when I turn it on, it just tells me It's intializing, then says it can't do anything because there is no boot drive avaliable. So yeah, do you need anything to get into BIOS besides the main hardware? Im not sure what the MB is, It's an intel Pentium D board, DVPS95 or something like that. Corsair Value Select 512mb sticks, and a 7800GT(Which is grossly overpowered for my parents) Pentium D 920. Everything worked a month ago. Oh and a Sound Blaster Audigy. On a site note, the case I bought my parents, has an air freshner in it.
