Basic Troubleshooting Solving General Problems (Continued) Problem Blank monitor screen. (continued) SCSI hard drives are not recognized after being installed when running under Windows NT. Cause Computer is in Stand By mode. System ROM is bad; system is running in Failsafe Boot Block mode (indicated by one long beep and three short beeps). The energy saver feature has been enabled. The RGB (Red, Green, Blue) input switch on the monitor is incorrectly set. You are using a fixed-sync monitor and it will not sync at the resolution chosen. The VGA/BNC selector switch is not properly set. SCSI drivers were not installed on the system prior to the Windows NT installation. Solution Press the power button to resume from Stand By mode. Reflash the ROM using a ROMPaq diskette. See the "Failsafe Boot Block ROM" section of the Desktop Management Guide for more information. Press any key or click the mouse button and, if set, type your password. Set the monitor's RGB input switch to 75 ohms and, if there is a sync switch, set it to external. Be sure that the monitor can accept the same sweep rate as the resolution chosen. Set the selector switch to agree with the cable connection. Install the SCSI drivers on your system first, then install Windows NT. To download SCSI drivers for your Compaq system, visit the Compaq Web site at http://www.compaq.com/support.
