I was half way through a system restore, when we had a power failure. Because of this, all system restore points won't work. The drivers for my CD/DVD drives won't work. I tried to do a system restore from the CD that came with the pc, but because my hardware configuration is incomplete, it won't re-install. I've tried looking for the cd rom drive (it's an ATAPI) without success. Can anyone help. The sound and graphics drivers have gone as well.
