Help w/ New Build

[smittysan89]

Hello, I finally got all of my parts and screws to put together my system. Everything is put together and everything set up, but when I turn my power switch on the system starts fine then the motherboard fan stops, then the heatsink fan, and I turn off the system afraid the chips will burn out. My case fans seem to keep running. I cant figure out what is causing this but over and over its the same thing.

FOR NF4 LANPARTY USERS
I have a DFI lanparty NF4. So there are the lights on the mobo and all lights go fine until the fans stop then the "VGA detected" light stays red and then i have to turn the system off.

Does anyone have any suggestions at all? Any ideas? Thanks alot.

Verify that all 4 power sources are plugged into the mobo, make sure any power plugs on yer vid card are connected. These probs are just odd as hell, I just rma'd the same board. checkout dfi-street's forums too. They have actual dfi techs on hand.

Well thing is my XFX 6600GT w/ VF700 doesnt have a spot for a power cord. But I dont see how that would affect the NF4 fan to shut down and then in turn the heatsink fan.

this is normal behavior for the lanparty nf4 boards. if you really are worried you can change options in the bios to disable thermal throttling and force constant max speed on the chipset fan, etc...

What do you mean its normal behavior? How do i fix it? What is thermal throttling? Do you think its safe to run the computer for say 60 seconds to fix bios while the fans on the NF4 and on the heatsink are not moving?

He's saying that the board monitors the temperature of on board components, e.g. the CPU, northbridge etc. and controls fan speed accordingly. You can turn this off in the bios and force the board to run attached fans at a given RPM constantly. The idea behind this was to maintain the cooling capacity of the board while minimizing noise. I personally don't care if my pc sounds like a leaf blower, but some people take noise very seriosuly.

So you really think this could be the reason and would cause my chipset fan and cpu fan to turn off completely?

Try building it out of the case. The board grounding against the case can cause the problem you're describing.

Lay the board on the foam it came on when you bought it. Hook up your monitor, keyboard, and mouse. Don't worry about the drives at this point. Then, short out the power pins ... the ones where the power switch connects ... for a brief second with a screw driver. Hopefully, all fans and powersupply stay running.

If it runs out of the case, try using spacers between the case and your motherboard to prevent your board from grounding out.

smittysan89,

(A) If you can boot into BIOS,

go into PC Health Status (on the 1st screen you'll see in BIOS, it's the bottom entry on the left side of screen) and change "Shutdown Temp" to "Disabled."

If you can't boot into BIOS, try continuously holding down both the INSERT and DELETE keys while booting.

"Insert" forces it to load optimized default settings for just that bootup, and to ignore any custom BIOS settings, and "Delete" tells it to open BIOS.

(B) Even though you already know for certain that your cpu heatsink is properly mounted onto the cpu, just go ahead and take a minute to triple check that again. Tiny misalignment there could be causing cpu overheating, triggering safety shudown, although that wouldn't be causing the shutdown of your chipset fan that you report.

(C) Only other thought is, I've never owned a modular PSU like you have. I understand you can connect / remove various lead wires from a modular PSU. Could a wire possibly be connected into the wrong point on the PSU, causing wrong voltage on that one wire?

I have your same mobo, and am very happy with it. Best mobo I ever ran. You WILL overcome the problem and be successful with this.
