Motherboard issue

just installed a new power supply and the motherboard came on then turned off and came back on a few seconds later and stayed on,but the monitor never came on.the motherboard is a supermicro c2see I used a 4 pin plug adapter to 8 pin plug for the cpu could that be the problem? or is the motherboard bad?

    Have you tried without the adapter? That may be causing interference.

  4. Hi, melanie.

    That huge list of things that you posted doesn't help at all.

    Here's what we need:
    Brand and model of computer if prebuilt.
    Model of CPU that you have installed.
    How much of what kind of memory do you have installed.
    How many of what kinds of drives .
    Brand and model of any video card.

    Power supply details. In a home built system, all we need here is brand and model. In a prebuilt, if you cannot give brand and model, we need details like voltage and amperes.

    All power supplies should come with a label telling you this.So the information we need would look something like:
    5 volts - nn amps
    3.3 volts - nn amps
    12 volts - 2 outputs, nn and pp watts
    Total 5 volt and 3.3 volt power - nnn watts
    Total 12 volt power - nnn watts.

    You said you changed power supplies. Why? Did the original fail? Did you upgrade with more power hungry components?

    All of this seems like a lot of technical details, yes? Well, you are right. :) But we can't make house calls. :(

    Now, if I had been a little more lazier, I would have just asked you, "Did the old power supply still work when you removed it? If so, what happens when you reinstall it?"

    That 4 to 8 pin adapter that you tried to install is useless. If installed properly, it will not hurt anything; but it will not really do anything for you either. Besides, most replacement power supplies come with either 4 and 8 pin CPU power connectors or a single 8 pin connector that can be split in half for motherboards with 4 pin plugs.

    To help you get started troubleshooting your system:
    Build it yourself:
    I include this because it will give you a little more familarity of how your system goes together.

    And this is our primary troubleshooting thread:

    This gets a little more complicated. You may want to have a knowledgable friend (one who has built several systems, if possible) help here.
