Question about DFI Motherboards

DFI Infinity NF4 SLI won't start

I bought a DFI Infinity NF4 SLI on eBay (seller has 96.3% positive feedback). I moved it into a case that had been running a DFI Infinity NF4 Ultra until it got stuck, perhaps heat related. The SLI turns on for less than a second before turning power right back off.

DFI tech support suggested I clear the CMOS setup RAM which I did (over night). It still behaves the same way. All the fans spin up for a moment then stop. Most drive lights come on for a moment then go dark. I even went so far as to unplug everything: video, RAM, storage, front panel lights, ... Only the CPU, PSU, and power switch were still connected. It lights up for a moment then goes dark and silent.

The standby power light near PCI slot 3 is on. The RAM power light comes on momentarily with the fans and other lights.

What do I do to make this come up?

Thanks,
Steve Florkey

    Thanks, Mike. Another PSU did the same thing. So far I have a lot of errors. I'll hope for a few more things to try.

    The two motherboards behave a little differently:

    The Infinity NF4 Ultra turns on and stays on until I turn it off or unplug it, but it gets stuck early in the POST. I just got a PCI POST reader so I'll use that to look see the sticking point which should help identify the solution.

    The "new" Infinity NF4 SLI turns on for only half a second before turning itself off. As mentioned at the top of this reply, I get the same behavior from a new Thermaltake 600W or the Silenx 450W initially used with the NF4 Ultra. This board came with the CPU installed with the AMD heatsink and fan (and too much thermal grease, but that was corrected when I swapped the CPU with the Athlon64 I bought with the NF4 Ultra).

    1G (2x512) of RAM is installed. Both motherboard power cables are connected. The motherboard is on 6 stand-offs with nothing else able to touch the solder side. An nVidia video card is in the top PCIe slot. The southbridge cooler and a case fan are plugged into the other (than the CPU cooler) two fan connectors. The front USB connectors' cables are plugged into the motherboard, but nothing is plugged into the front panel. Keyboard and mouse (KVM switch) are plugged into the back panel. Nothing else is plugged into this motherboard.

    If we cannot fix this at home, where is a good motherboard repair facility? I'd love to get both boards up (with new southbridge coolers).

    Thanks,
    Steve

Hi steve, PC repair is trial & error. I suggest you replace the power supply or test the power supply in another PC that also uses 4 SATA drives & two PCI-E slots for starters. Two boards with the same problem is odd. You must have the CPU & fan connected, memory installed, ATA 24_pin main power plugg connected (Page 17 in manual). 4-pin_12v power connected which is located (Just to the left of DDR1 memory slot). Looking at you're board the power supply should be no less than 500w.
CPU must have thermal grease between CPU & heat sink.
Even though you have fans running & LED's on & flashing, the power supply seems to be the first item to check. Make sure the bottom of the motherboard is not touching the PC case.
Try the above & post you're finding here.

Good Luck!
Mike

I am searching a site where download the manual for dfi lp ut nf


Not a problem! I have it right here for you.

http://us.dfi.com.tw/portal/CM/cmproduct/XX_cmproddetail/XX_WbProdsWindow?action=e&downloadType=manualTab&windowstate=normal&mode=view&downloadFlag=true&itemId=479

Scroll down this page a little. There are tabs going across that you will see.
BIOS, Driver, Manual, Technical Doc., ABS Profile, and a tab that has an arrow pointing to the left.

The Manual tab should be highlighted. If not. click on the Manual tab.
Scroll down to the Fourth file listed.
-> Motherboard Manual English/Multilingual Manual <-
Under this heading is -> 87910551.pdf <-
The 87910551.pdf is in Blue. Click on this for the Motherboard Manual.

You have Adobe Reader on your computer. Adobe Reader uses PDF files. I use Adobe Reader 9.1 If your version is not at least Adobe Reader 9, I invite you to go to Adobe.com, and update it. Makes downloading PDF files real S-M-O-O-T-H.

If you do not have your downloads set to go to your My Documents folder, this PDF file will go to your desktop screen.
To look at it, just double-click on the file name.

This same link I gave you has the drivers you requested. Just click on the Drivers tab. Also BIOS updates. As you can see on this Manuals page, the manual for how to use Nvidia RAID is there too.

DFI NF4 INFINITY MOTHERBOARD NON BOOT


sounds like a hardware problem. try unplugging all external devices including keyboard and mouse but not monitor. test if it works. if not, open the side of the case and remove the little battery found on the flat motherboard for 30 seconds. then slide it back into place. now try to see if it works. if still nothing, check to see if there are motherboard jumpers (they will be 2 tiny pins on the board with a clamp over the top of them, you probably wont find them), if you see the jumpers, move the clamp to the spot that says "clear cmos" then put it back. or if your motherboard has a clear cmos button on the board, press it and try the computer. if it still will not boot, it could either be the flat IDE cable (for a hard drive or cd drive) or the power supply which means you will need to purchase either a new power supply or ide cable. if all still fails, i would say the motherboard is shot.
