New motherboard won't boot
I am unable to boot a new K7VM3 motherboard that I am installing in an
e-machines H2482 computer case. I am using an Athlon XP 2400 CPU and 512-meg of DDR RAM, which both were working correctly in another computer. After installing the RAM, CPU and CPU fan, and connecting a 300 watt power supply, I: 1. Connected the power cable to the motherboard 2. Connected a monitor 3. Connected the front panel power switch 4. Turned on the power switch on the power supply 5. Turned on the front panel power switch The first time I followed these steps, the monitor did indicate the motherboard was booting (startup routines, prompting to insert boot floppy). I then did the following: 1. Turned off the power supply switch 2. Conncted the Hard Drive, Floppy Drive, CD Burner and CD ROM to the mother board with ribbon cables 3. Connected the power supply cables to the Hard Drive, Floppy Drive, CD Burner and CD ROM 4. Turned on the power switch on the power supply 5. Turned on the front panel power switch At this point the CPU fan began spinning, but the motherboard would not boot - nothing would appear on the monitor screen. Then I did the following: 1. Disconnected everything from the motherboard except the monitor and the power supply 2. Turned on the power supply switch 3. Shorted the power switch pins on the Front Panel Connector. Again, the CPU fan began spinning but the motherboard would not boot - nothing would appear on the monitor screen. I tried resetting the CMOS but this had no impact. Any ideas on what's going on here? |

If you have tested this in another box (W/Power Supply) , then the
only thing that's left is the power supply, power button , or Case wires. I have built emachines before and found that some power supplies are not a standard main conector harness wiring pattern. Some have a reverse of 2 wires in the harness (by color) . I did not burn anything out, but it really P***ed me off when I found out. Can't seem to find the web page for color codes anymore but if you search you should be able to find something. I also ran into this problem with some dell models when replacing burnt power supplies. Also a reverse polarity of the led wires for the case could make a non boot for some motherboards . This may be the place to start. Some bios instructions can be sooo picky. I hope this helps and let us know how you make out. |
