    I recently (just now) built my own pc

    specs:
    AMD Athlon 64 3800+ Socket 939
    Foxconn SKT939 Nforce4-SLI
    Western Digital WD2500KS Caviar SE 250GB
    Asus 7600GS SILENT 512MB DDR2 PCI-E
    CRUCIAL 1GB DDR PC3200 400MHz 184-PIN X2
    LiteOn DH-16D2P 16x52 DVD-Rom Black Bare Drive - OEM
    NEC Optiarc 7173A 18xDVD±RW/RAM DL LabelFlash Black Bare Drive - OEM
    Newlink 5 Port USB 2.0 PCI Card with 4 External Ports and 1 Internal Port
    Arctic Cooling (AC-FRZ-64P) Freezer64 Pro Socket 754 939 940 CPU Cooler with Heat pipe cooling Pro Ver
    Antec P180 Black SPCR Advanced Super Mid Tower - No PSU
    Antec EarthWatts 430W 80%+ Efficiency PSU - 80mm Fan 4x SATA PCI-E

    reading the motherboard manual and plugging in everything it says to plug in, and trying to turn the thing on to see if it works, it does not turn on. when i flick the power switch on the PSU to on the keyboard light turns on then off. but when I press the power button, the computer wont turn on. any suggestions?

    Do you get the green LED on the main board?

    Also recheck all your connections.

    fixed that problem now another one! (i think) solution to the first problem was that the power LED plug had 3 connectors when only 2 was supposed to be in use so the plug next to it (the power switch) only had one connector which meant it couldnt draw enough power to start up.

    anyways second problem: after turning it on the computer stays on the start up page IE: "press del to enter BIOS" - THAT page keyboard has power and flashes lights when the computer turns on but it has no response when i try to go into the bios and stuff.


    I dont have windows installed yet.

    disconnect all your drives from the mainboard, to see if the machine responds

    After disconnecting both DVD drives, it gets to the next screen but it says "CMOS checksum error" and the keyboard wont respond again. CPU fan stops as well


    EDIT:: Tried turning it on with the drives connected and it gets to the same screen and freezes, the CPU cooling fan stops as well.

    It only stops on the first page if i press a button on the keyboard

    Does the part where it pauses say something about BIOS defaults?

    Use the CMOS clear jumper on your mobo, then when powering on, see if there is a message about loading defaults or entering setup. load defaults, then enter the BIOS to set it up how you want.

    Right, I'd say clear the CMOS with the jumper and then go into the BIOS, load optimized defaults or some similar option, then save and restart.

    i've cleared the CMOS with the jumper a few times now, however it still wont let me enter the BIOS, still keeps freezing when i press DEL on the keyboard. Only CPU fan stops but the case fans still keep going.

    out of interest, is it a usb or ps/2 keyboard?

    Also which Foxconn board is it (there are 3 listed on foxconns site with the NF4 SLi chipset; NF4SK8AA-8EKRS, NF4SK8AA-8KRS and NF4SK8AA-8EKRSH)?

    The BIOS is the same for all three after some digging, and there has been more than one BIOS release, although the notes for the releases are just one like long possibly not showing all items altered (i.e. for version 538W1P31 "1. Patch AMD 3500+ CPU unstable issue." and version 538W1P32 "Update agesa code.").

    chrisb2e9: i've cleared the CMOS by setting the jumpers AND by remobving the cell battery;
    Golygus: its the NF4SK8AA-8EKRS, PS/2 keyboard

    after disconnecting from the PSU, use the jumpers and take the cell battery out and put back in again, and then plugged in the PSU, waited for a bit and then tried yes.

    Keyboard is new but yes i have tried another keyboard but to no avail :(

    Starting to sound like your mobo might have a bad BIOS chip. I think an RMA might be in order, but I'd wait for confirmation from someone else, as I've never heard of this happening, but there might be a simple fix I'm missing.

    It might be that the CPU is newer than the BIOS recognizes. If you can fit an older CPU and then use a boot floppy to upgrade the BIOS to one that supports the new CPU, that might work.
