Sorry for the misspelling problem causes that had little or no place, but I also have a computer with a Pentium 4 HT 1 GB of RAM, an Nvidia FX 5200, 2 hard drives of 80GB each of the two, 2 optical drives for CD-DVD burner ROM, 2 Sound Card Sound Blaster Live with an M-Audio Delta 44 and a PCI modem. As tension I need to feed them.
