I am unable to boot a new ASRock K7VM3 motherboard that I am installing in\nan\ne-machines H2482 computer case.\nI am using an Athlon XP 2400 CPU and 512-meg of DDR RAM, which both were\nworking correctly in another computer.\nAfter installing the RAM, CPU and CPU fan, and connecting a 300 watt power\nsupply, I:\n\n1. Connected the power cable to the motherboard\n2. Connected a monitor\n3. Connected the front panel power switch\n4. Turned on the power switch on the power supply\n5. Turned on the front panel power switch\n\nThe first time I followed these steps, the monitor did indicate the\nmotherboard was booting (startup routines, prompting to insert boot floppy).\n\nI then did the following:\n\n1. Turned off the power supply switch\n2. Conncted the Hard Drive, Floppy Drive, CD Burner and CD ROM to the\nmother board with ribbon cables\n3. Connected the power supply cables to the Hard Drive, Floppy Drive, CD\nBurner and CD ROM\n4. Turned on the power switch on the power supply\n5. Turned on the front panel power switch\n\nAt this point the CPU fan began spinning, but the motherboard would not\nboot - nothing would appear on the monitor screen.\n\nThen I did the following:\n\n1. Disconnected everything from the motherboard except the monitor and the\npower supply\n2. Turned on the power supply switch\n3. Shorted the power switch pins on the Front Panel Connector.\n\nAgain, the CPU fan began spinning but the motherboard would not boot -\nnothing would appear on the monitor screen.\n\nI tried resetting the CMOS but this had no impact.\n\nAny ideas on what's going on here?
