OK, so I recently purchased a Dell XPS 630, and I knew it had problems, but I have also seen it in action and knew it worked. Anyway, I turn on the computer and nothing comes on screen. It says that the monitor is going into power saving mode, and I'm not sure what to do. Everything turns on, all fans work, graphics card fan works, so I know the motherboard is ok. I have the Nvida 9800 model. One card didn't work, so I am down to one Geforce 9800 gt 512mb. Since there is no internal graphics, I can't get into the bios and re-install the 9800. Any suggestions? It would be greatly appreciated.
