  1. I went out and bought the mobo before the case because I am buying the case online and I bought the mobo in a store. The mobo did not come with screws so I was wondering if they usually come with the case. Also, I read online that if the back of the mobo touches the case it will short out. How do you keep to mobo from touching the case so it does not short out? I heard about riser pins. I don't know what they are or where to get them. Would rubber washers around the screws work?

    all cases that i have bought online so far have come with rise pins. They have also come with a quite a few screws. So you shouldn't have to worry so much. Also when manufacturers make motherboards they create a non electrical zone around the screw holes so the metal won't harm the board. But in any case, the computer cases should come with little red plastic washers that you can use .

    some cases come with standoffs, some don't. also some motherboards come with them too. If neither your case or motherbord come with them, they only cost less than $5 at a computer store or radio shack, etc.

    the screws are supposed to touch the case, that is why the mounting holes on the motherboard have a metal ring around them, the mounting screws not only attach the mobo to the case, but they also keep it grounded so that static electricity doesn't build up and damage any components. The back of the mobo cannot touch the case, but the screws should, so don't use washers or anything to insulate it.

    -in some boards, a mounting hole may be too close and will actually short the board out, in these cases, either don't use that hole, or use a plastic standoff (no screws, the plastic tab locks the board on)

    Hi

    If the screw hole on the mobo has a metal ring, it should go to a metal standoff in the case, unless the mobo manual says not to install it this way. Mobo screw holes that don't have metal surounding the screw hole should use plastic standoffs to attache the mobo to the case.

    Thanks for your help. It does have metal rings.

    Now can anyone tell me what the difference is between Athlon and Athlon FX?

    Athlon 64 is a single core 64 bit processor that is available from 1.8 Ghz - 2.4 Ghz and they are called Athlon 64 3000+ through Athlon 64 4000+ respectively. Those are socket 939's. The FX versions are also 939 but are available 2.4 - 2.8 Ghz and these are the real gaming CPU's. Both FX and 64 run with 2000 Mhz buses. The FX's are what Alienware and Falcon Northwest use in their extreme gaming machines. Athlon 64 also has a line called X2 which is a dual core line up.

    The FXs are a lot more. I'm going to get a regular Athlon. Thanks for your help.

    The FX cpus are state of the art, top of the line cpus. At this point the average user just doesn't need that much (all a matter of opinion of course).

    I have the Athlon64 3700 and it is AMAZINGLY fast for my needs (which mostly comprise of senseless online violence).

    I got my case and put in my motherboard and now I got some more questions.

    I plugged the leds, power button, and reset button into my motherboard. My motherboard manual showed what pins they went to but neither my case nor my motherboard specified how they should be put in. Which way does the text on the wires usually face? I got the vertical ones going to the left and the horizontal ones going down. Can you tell from this picture if I have it in right?

    It varies from maker to maker. Does your case manual tell you which side the negative should go on? That is the way I usually tell, then the white wire is typically the negative. But it varies...

    Good news is, if you make a mistake it simply won't work. Switch 'em and try again.

    here here

    i agree depends on the mobo manafacturer however try with the writting facing you first im sure that will work and another way to tell is
    look at the system speaker plug does it have + and - if so
    put on look at mobo does it have + and - if so

    match + to + and - to -

    wich ever way thAT WRITTING IS FACING FOLLOW THAT THERE AFTER

    EXCEPT BACKWARDS ON THE RESEST SWITCH OK

    The only thing it specifies is the power led and the hd led. I did have the hard drive led backwards if white is negative. Correct me if I'm wrong but does the power switch and reset switch matter for + and - if all they are doing is completing a circuit?

    Yes It Matters

    yes it matters because it sends a small votage to activate the power swith inside the power supply also double check you have plugged in the yellow and black cable to your p4 socket or you might blow ya mobo
    blue is neg and white is pos :knock:

    Here is my manual. Can you tell me what is positive and what is negative?

    Also, how can I blow my mobo if that other guy said that the worst thing that could happen is that I would need to try putting in the wires a different way?
