AIW 9700 PRO Power fail

Hello,

Ok heres the situation. I just purchased a Athlon 64 bit 3000 Socket 939 + a MSI NEO2 (nforce 3 ultra). I previsouly had an XP 1800+ (oc'd to 2100+) and a Gigbyte Ga-7vaxp. I still have my ATI AIW 9700Pro vido card. This card worked fine in my old system but my new system it is having issues. I input the vid card, hook the power up, computer powers up for half a second then powers down. Then i have to switch the PSU on and off to reset it. Now if i disconect the power to my Vid card the computer doesnt power itself off but however it wont boot up as the power is not in the video card. I tested my ATI Radeon 9600XT in this machien to make sure it was not the mobo and it works fine. I knwo a bunch of you will say you need a better Power supply, but I got the Antec True control 550, which I knwo my self is enough, and its rated near the top PSU if not the top. My AIW 9700 Pro is running in my old Mobo and cpu with a Seagate 8MB 250 GB, 512 DDR 400 C2.5 Antec 350 Watt. It is runnin fine no issues so it is not the actuall vid card.

Now I was reading some other forms and about this issue, and one said that it is the initial draw from the powersupply that is killing it. THE AIW version initially draws a large amount, and now with the new mobo it draws even more which causes the PSU to reset it self, maybe soem kinf of serge protection. I would really liek to be able to Use my vid card in my new machien as that is why i purchased the new mobo and cpu it to get more out of my Vid card!

This is my complete specs

Athlon 64 3000 (socket939) (1.8GHZ now oc @ 2.15GHZ)
MSI K8N Neo2 Platnnum nforce3 Ultra(MS-7025)
Corsair twinx 1G 3200C2
2x 80 gig WD raid 0 not the Jumbo
1 x 80 sata (WD800JD)
True control 550 PSU (Antec)
ATI Radeeon AIW 9700 Pro

ANd it has nothing to do with my OCing my cpu as I had the same problem before I overcloacked it.

Does anyone have any solutions? Has anyone had this problem and fixed it?
Any help would be much apreciated.

Thanks in advanced.

Try hooking it up with a single direct plug to the PSU instead of sharing it with another device...also ATI has been know to exchange the 9700's with 9800's if there's a problem
 
Yo, I forgot to mention that I already tried that, I unplugged everything except the Mobo and Vid card but same problem. I was goign to contact ATI when this problem occured but thier tech support was down till yesterday cause of holidays. I will see if they will replace my Vid card for the 9800. Thanks man, anyone else got some ideas?

If the card worked fine in the other system, then it's probably not the card. It could be a failing PS or a mobo problem. I would switch the power supplies and see what happens.
 
check the power pins on the top part of the 9700. The power connectors on the 9700 are very cheap they bend and can break easy. A solder joint on one of the pins could have broke loose.
 
I do not think its the connectors as it works fine in my other computer set up. I checked the net for problems with my mobo and the video card and no one has had the problem and my mobo works fine with any other vid card ive tried. Ill check the connectors tonight though and ill tray another PS tonight as well.

Any other ideas guys?

FNC JON
 
Yes and that is the only thing that is different between the two com set ups. So I was thinking that that is the cause of the greater power consumption at the start up. What is your thougth about the 4 pin connector?

FNC JON
 
No, the ATX 12V connector goes from the PS to the mobo and provides extra power to the mobo. You need to have that plugged in. The only way it would cause trouble is if your PS does not have the connector to provide the extra power to the mobo.
 
K yah the connector is there and it is plugged in. How much extra power do u think the connector draws from the PS?

FNC JON
 
I'm not sure what you mean. You seem to be saying that having more power on the 12V rails might be causing the trouble.

You can try running the board with the connector unplugged if you think it is somehow causing the trouble. A lot of people don't even know about the ATX 12V spec and are running their boards without an ATX 12V supply. I know because there have been a few threads here where people had no idea what ATX 12V was, even though it's been standard for more than a year now. They just used their old ATX supply with the 20pin connector and didn't even know about the extra 12V connector they were supposed to have and use. They get away with it until they add something that causes the board to need more power.

I can't imagine that having less power on the 12V rail is going to help the mobo, though. That's what will happen if you unplug the 12V connector.
 
Hehe sorry about that, Yah I am saying that maybe it is causeing the power issue. Im not saying that the 4 pin connector is defective or anythign but i am sayign combined with the aiw 9700 pro and the std 20 pin connector that maybe the initial draw from the PS is cause the PS to pull some kind of protection feature that shuts it off right away. I am assuming it is a protection feature as I have to turn the power supply off then on to get it working again. This same thing would happen if i crossed the positive and the negative on the 12v rail on one of the power cables ( ie i did it hooking up some extra fans).

I will try it at hoem tonight unplug the 4 pin, if the computer starts up I knwo its the inital draw, as my older mobo doesnt require the extra 4 pin connector so it doesnt use the etra power from the PS.

What do you think?

FNC JON
 
OK so far no luck, its not he pins on the vid card, I tried two power supplies but neither of them would even boot my machine with another video card, not enough power i assume they were only 300 and 350 watters. I have notived before that this card also had the same issue in my freinds machine which is a msi k7n2 which had a antec 350 watt. So now its possible that its related to msi or antec as I too have a MSI and ANtec. THis is gettning annoying. ANyone have some ideas for me??
Thanks

FNC Jon
 
Try another powerful powersupply and try the card in someone else's AGP system. That will narrow it down. One of them is bound to work, since it worked in yours. I highly doubt its an MSI mobo thing. Most likely the card or PSU.
