SOLDIERX.COM Nobody Can Stop Information Insemination

Ok, so I ran DBAN on my brothers laptop with no problems. Went to restart the computer and now I get nothing showing up on the monitor. I'm talking no boot screen, no way to get into BIOS, nothing. All the LEDs come on, I can hear the fans running, if I put a disc into the drive I hear the drive spinning the disc. It's an old ass HP ze5470us. I have tried reseating the RAM in the computer but that has still yet to produce anything. Any ideas, besides your fucked? I'm hoping that the integrated graphics card didn't all of a sudden just take a shit.
