Question about Foxconn NF4UK8AA-8EKRS Motherboard

Won't boot or start, fans and leds work

I just bought a new NF4UK8AA-8EKRS. Here is the system I have:

939 AMD X2 4200+
768 MB RAM DDR333 (I know, I need more and better)

I have connected everything, checked it twice or three times and when I turn the system on nothing happens. The fans spin and the LEDs light up but the system does not boot, the cd drives do not spin, nor does the HDD. I have tried everything I can think of, removing RAM, reconnecting/changing cables, etc.

I am using a 400W Raidmax power supply and am thinking that this may be a bit underpowered. However, with people I have talked to they have said it should be sufficient. I am hoping the mobo is not DOA.

Anybody have any thoughts?

Re: Won't boot or start, fans and leds work

I removed the video card, ram and plugged in the remaining 4-pin connector. i gradually added components. It powered up and posted when i installed the video card. however, when i plugged in the hdd it failed to post.

are there setting i can play with on the mobo that will allow the hdd to work, or does this sounds like a power supply problem. ie, lack of juice? is there a way to test the hdd, i do not have an extra lying around. i have a ata133 IDE, not sata hdd.

NF4UK8AA-8EKRS motherboard no longer sees either of the SATA hard drives. Any thoughts?

Hello here is the homepage:

Try to enter the bios, and look for the harddrive settings.

The driver is needed for the pci card, do you have them ??

Your friend could have damaged the mainboard.

Good luck

Foxconn NF4UK8AA-8EKRS doesn't recognize CPU

Smithbrother is right...

the file you need is here:

You'll have to get yourself a BIOS flash utility. There are some simple, good boot disks for that here:

then you'll need to boot to that disk (not into Windows), and run the flash utility provided at the previous link. Once your BIOS has updated itself, you should be good to go.

This is a known issue with early BIOS revisions of your board.

No boot on start up all fans start but no video

I had same problem!
I figured there was something wrong with my memory because that is what the manual says the constant beeps mean.
I bought a new PNY memory stick 1 gb DDR and got the same beeps when i put it in.
So being totally disappointed I tried putting the Stick in the #3 DIMM. I booted up and IT WORKED!
I have not called tech support or tried both 1 & 3 DIMM together but I will try after I set up the rest of my computer.

Could be one of three things, either your motherboard is faulty (check the capacitors for bulging) and is not getting the power to the processor, the processor itself has faulted, or it's simply a flat cmos battery, as this can cause none starters.

New build computer wont turn on (ASUS A8N32-SLI Deluxe Socket 939)

The ATX power supply needs to have pin16(PS_On#) to be connected to COM for it to work. When you press the power switch on the front panel of the computer, you are essentially making this connection. Check that the cable from the power supply to the motherboard is making good connection. You can verify operation of the power supply by shorting Pin16 to pin17 on the powersupply output, with a paper clip. Pin16 is usually a green wire and 17 is black. Hope this helps. -Vish

It sounds as if you have a flat CMOS battery, remove and replace. To delete the password and bios settings locate 'JBAT1' terminal on motherboard and put jumper from pins 1-2 across 2-3 for a few seconds and then back to pins 1-2. You will have to reset time and detect drives in standard CMOS settings.
