I have a computer that only boots to the PCI device listing screen. I have switched out the power supply and RAM with no change. I have taken out the SCSI card in the computer and all other non essential devices, but I am still haveing this problem. Also, once or twice I have seen little green rectangles on the PCI device screen. Could this be a video card problem? (Dont have another card at the moment) Anyone had a problem like this before? Lastly, the user says that it worked until last Monday when I went on vacation.
