    I have just purchased a new Motherboard, CPU, Case for my PC

    1 Gigabyte GA-7DX Processor
    1 Athlon 1.4Ghz Processor
    1 N880 FULL-TOWER ATX-300W CASE

    After building my PC I discovered that the PC wouldn't power up at all (the fan for the power supply wouldn't even spin).

    So what I decided to do is to go down to my local PC World and have them test the power supply (as well as make sure that i wasn't doing something stupid). After returning to PC World I then was told that they had swapped my power supply over with another power supply, but still nothing. Due to the problem not being the power supply the guy in the shop said I think it is probably the motherboard, so I then sent the motherboard back to the place I purchased it from.

    The motherboard was then tested and results were 'After Testing Your Motherboard We Have Found No Faults At All, It Works Perfectly'.


    Please Could Someone Assist With This Quite Major Problem

    Many Thanks

    Matt

    The most obvious place to start is.

    1. Make sure motherboard isn't grounding out to case when you install it.
    2. Make sure power on leads from case power button are connected properly to the motherboard.
    3. Make sure power connector to motherboard is secure.
    4. If power supply has on off switch on back, make sure it's on.

    sorry if i'm being a bit obvious. When you connect up and turn on power use an avo meter to check the power supply unit either side. ie 110volts in----> X (amount) volts out. This will at least give you another test on the power supply to discount that and get to look at the next thing in line?[

    I'm not sure if your new mobo is set up the same as mine was from the factory but if it is you'll need to check your CMOS jumpers.

    Mine was set to Clear CMOS Memory and it wouldn't do anything until I set it to Normal Operation. I can only assume this is done to prevent the battery from wearing out prematurely if the mobo sits on the shelf for a long time.

    I've got a host of other problems with this, my first home-built, computer but that was the first one.

    did you check the standoffs that hold the motherboard away from the case, no shorting.

    Double and triple check the leads from the power button to the motherboard.

    Make sure you have voltage on the acline outlet, sorry it's happened.

    Pull everything out except the processor, memory, and vid, will it start and post.

    Remove the motherboard from the case and lay it next to the unit, hook up the power, with the memory and vid card connect, will it post.
