    i finally built my new computer.. but when i tried to boot it up...it did nothing.. the power
    starts but nothing else happens. monitor stays black, but the power and hdd lights on the
    tower light but, but STAY light..no real work is processing it looks like. im pretty sure
    everything is put together correctly. the only questionable wire i had were two wires from
    the case (single jumper type plugs - like the hdd led ones), but they were only labeled with
    a + and a - each. i wasnt sure where to put those, so i put them on the pled jumper.. since
    thats the area where the rest went..and just so i know for certain, on those jumper wires,
    the side with the little triangle is for pin 1 right?
    ok, heres my setup..

    AMD Athlon 64 X2 4200+
    NEC Black IDE DVD Burner Model ND-3540A
    CORSAIR ValueSelect 512MB 184-Pin DDR SDRAM DDR 400
    Maxtor DiamondMax 10 6L200P0 200GB IDE Ultra ATA133 Hard Drive
    ASRock 939Dual-SATA2 Socket 939 ULi M1695 ATX AMD Motherboard
    Antec TruePower 2.0 TP2-550 EPS12V ATX12V 550W
    POWERCOLOR R43CA-GD3D Radeon X800GT 256MB GDDR3 PCI Express x16
    SONY Black IDE DVD-ROM
    COOLER MASTER Centurion 5 CAC-T05 Case

    the only other aspect i was 100% sure on was the power supply it self.. it was ALOT
    different than im used to.. it had extra cords for SATA and PCIE, which are all still
    unplugged since i figure im not using them.. do they NEED to be plugged in? anyway..
    please any help would be great.. id had to think i just spent $1000 on a giant paper
    weight.. thanks ahead of time again.. :confused:


    ps.. i did just notice that i dont have anything plugged into the 12v port on the mobo.. but
    i dont think there was anything that would fit on there from the PS.. my main power cord
    was a 24 pin, with a 4 pin breakaway.. my board uses a 20pin so that 4 pin was taken off..
    do i use that?? i think i tried that, but it didnt fit right.. should i try it again? thanks again

    I don't believe that it will boot up without the power plug being plugged into the 12v port on the motherboard. That Atec power supply does have a 12v power plug.

    The 4pin 12V connector must be plugged in to the motherboard for most AMD processors, and I'm fairly sure including yours. The symptoms you descibe are typical of the CPU not being powered. On my motherboard, and I think most, the 12V CPU 4 pin connector sits right above the GPU.

    You have a 4 pin 12v power plug on the motherboard just to the left of the CPU and to the right of the 20 pin at the top edge. It must be plugged in. If your PS doesn't have this plug then you must get one or an adapter.

    ok.. i just figured out which wire goes in there.. i was thinkin it was the 4 pin breakaway from the main power supply cord (24 pin > 20pin), but then i found another wire that fit better with a clip on the side.. none of these wires on the power supply are labelled so i didnt know which wire went where.. i knew i need to get that 12v in there, but didnt know which one went in there.. but looks like i found one.. guess its time to boot up again.. wish me luck...

    dont worry about thermal paste ,unless you have a cooling problem.the heatsink should have came with grey stuff on it.thats thermal paste.artic silver keeps your processor cooler ,but the stuff that came with your heatsink is fine

    I wouldn't suggest looking though, or you'll need to add more. (In other words, don't bother, and leave it alone, you're fine without it)
