NF7-M /9700 PRO Troubles

AuthorityAction

All of the sudden I can't use my AIW 9700 PRO with the NF7-M (with Antec True480 Watt). If the power cable is plugged into the card, the computer will shutdown right after the power is turned on. Without the power cord, power stays on but of course the card displays the error.

The onboard video works fine. I've been forced to use it ever since. Right now I'm at a LAN party with Park so we've been working on it. Basically us together--we've tried everything we can.

1. 2 PSUs at once (one for system, one for Video card alone)
2. Different molex connecters to the video card
3. Checked PSU Voltages (They're fine)
4. Reset BIOS Settings

Plus other minor things.

Right now it is working with a different board (MSI K3 Ultra--trusty little board). When the games wined down some, we'll pull out Park's 9800 PRO and see what happens then. We think it's probably the motherboard that is the problem, we just can't think of what about it.

TIA,
Jeff

P.S. Reason for NF7-M was I couldn't afford the 9700 until a little later

Did you try with a completely different power supply? With two different PSU's I'd be a little worried about differential voltage problems (depends on how the power on the AIW is supplied). What happened when you booted in this case?

Other than that maybe its some sort of conflict with the onboard video or the board has issues. Very wierd..

Try Disableing the onboard video. in the bios. then put the card back in and see what happens

The 9700 PRO used to work fine in it. It just all of the sudden stopped. This why we're so lost on what's wrong.

Update time.

We had 2 motherboards: NF7-M & MSI KT3
We had 2 power supplies: Antec True 480w & ChannelWell 350W (very cheap)

What the 9700 PRO works with:
MSI KT3 with Antec
MSI KT3 with ChannelWell

What the 9700 PRO does not work with:
NF7-M with Antec
NF7-M with ChannelWell

So we decided it's not a power issue. It has to be the motherboard. Except it used to work with the same exact setup it refuses to work with now. We've reset CMOS, disable onboard video.. nothing works. I don't believe that's it, because of how it doesn't work. It will power on for maybe a second, and then die. The board is still getting power as the red light is on. You cannot attempt to power on again unless you flip the PSU off then back on.

As said above, as long as the floppy power cord is not connected, it will power and and display the error message of proper installation of power cord. The computer only refuses to power with the floppy power cord connected.

So what could cause something like that--I'm so stumped.

We didn't pull out my 9800 PRO to see if it works, because we were dead tired at 6:30 AM when we decided to head home. I told Jeff to rebuild the computer, to double check every connection. He probably won't get around to it until tomorrow after school.

Please keep suggestions coming

Here's the update:

I took the NF7-M out of the case and set it up. At first it did the exact same thing that it had done before. Well I was feeling lucky so I tried again a couple more times. Well it turns out that it started working after a couple trys Then after it started up once it would only work randomly. After spending a lot of time messing with it going on and off it started working every time. I then put it back on the motherboard tray only to find that it wouldn't work. After trying more it decided to do its random working thing. So now its in my case and I'm running knoppix since windows doesn't like a new motherboard. Any ideas?

Sounds like your mobo has some janky traces around the AGP slot... I'd consider an RMA.
