Question about DFI NF4 ULTRA INFINITY Motherboard
Hi! I have a computer based on nvidia NF4 ultra infinity chipset. Two days ago I have noticed that the screen was frozen and it seems like the computer in halting. tried using keyboard to get it to work again but no success, so i have rebooted the computer with the power button (pressed it until it closed and then reopened it) it worked But after a couple of seconds it froze again so I turnned the computer off. Yesterday the computer failed to turn on when i tried to do so the screen didnt get any signal and there is a green led light that is blinking above the power button (telling me something is wrong for sure), so I started with a serious of acts to see where the problem comes from - but with no success. here are the things i have tried: 1. chacking graphics card - trying to put a different one restarting the computer with a new and without. 2 checking DDR - both ddr and each one alone to check if one of them or both of them is having a mailfunction. (usually when the problem has to do anything with memory the computer gives small sound beeps - this time it hasnt) 3. tried to dissconnect the DVDrom and some hard-drives - thought it might be a power supply problem. windows xp, amd athlon 64 x2 4.2 processor. please help... thx
Are the fans running - sounds like a PSU problem to me do you have a mutlimeter you can measure the voltage from the PSU - the motherboard website should have a manual, with pinouts and voltages.

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.

Could be the Hard drive or memory. Sounds as though it is reaching post. But dies after that, I would check both. I have seen both be the problem on other systems.
