    Hi,

    I was working on building a PC this weekend and can't seem to isolate my issue.
    I have installed a Core 2 Quad Q9400 w/the stock fan in a EliteGroup P45T-A motherboard.
    I'm using an Enermax EG701AX 600W power supply and a MSI R4850 video card. I am using a Thermaltake case I had from a few years ago. I have 2 sticks of 2GB Kingston DDR2 800mhz, which is compatible w/the MB.

    -I connected all the power cords (6 pin to the video card, ATX & 24pin to the motherboard, SATA to hard drive and DVD drive) along with the case cords to the motherboard (power, reset, hard disk).
    - I put in the video card, memory, hard dive, card reader drive in and connected the cables
    - I couldn't install the power/sleep/message LED because the Enermax clip has 3 holes while the MB has 2 pins (the hole in the middle of the in the clip doesn't have a wire, so it is only 2 wires, but 1 is able to make a connection.)
    -I connected the case fans to various power sources, including to the "system fan" 3 pin on the MB.

    When I connect the power cord and monitor, all I've heard so far is a little crackle each time, but nothing powers on.

    Any idea what I'm doing wrong? I don't think I short circuited my MB because I've been grounded the hole time.

    Thanks for your time and help

    Charley

    So completely dead huh- are all these parts new apart from the case?

    Absolutely sure you have the power button connector in the right place?

    (on new builds they tend to be the last thing I remember to put on - preferring to short the pins with a screwdriver - could give that a go- be careful though)

    Do you have any spare parts you can start swapping in and out? I'd go with the PSU first, then motherboard.

    is the mobo sittin on the back of the case at all? have you tried taking the motherboard out of the case sittin it on a anti static bag or somethin and seein if it powers on? have you check to see if your cmos is not set to clear? have you got another power cord you can try?
