Hi, yesterday i went to school, so i turned off my computer, and when i came back home, i start my computer and i get this message on my PC screen:

"You have not connected the power extension cable to your RADEON9800 PRO" Please refer to manual bla bla bla.

well, The card has worked for me fine for about 2 years, and i rechecked that there is no loose cables about 100 times, and there is no way thats the problem.

Could this error be caused by my card being fried? It was really hot yesterday (34 degrees) and my fan was full of dust...

any ideas?
 
thanks... the problem is that the power cable, i think, is glued to my radeon 9800. I cant disconnect it. Im afraid that i will break the card if i use more force trying to pull it off. On the other side, i disconnected and reconnected many times and it didnt help

do the manufactureres often glue in the cables?

Is there any other explanation why the error msg would appear? Im pretty confident that its not the contacts... i think

By the way, this happened to me once before. I started PC and it gave me same error, but that time i opened it, and... really did nothing other than made sure the contacts were in place... and when i restarted it was fine... so I am really confused...
 
I've got a Radeon 9800 Pro in my old computer. The power cable is not glued on, but attached with a clip. With a tiny screwdriver, you should be able to press down the clip and release the cable. The clip socket is glued onto the card, but I don't think that's what you're talking about, or at least that isn't what I'm understanding.

If the cable has gotten so hot that the socket fried to the card, yes, your card is fried and should be given a decent burial. 34c is not too hot, in fact its very cool, so cool that I wonder if the card is properly powering up. Another possibility is that the cable has coroded and shorted out. That might explain your previous trouble, if when opening the case you provided just enough movement to reconnect a corrosion spot. A coroded clip could seem to be glued on, but wasn't that way originally.

Cleeve is correct. A voltmeter would tell if there's power over the cable and across the connection. Maybe, if its just a bad wire, a new wire could be spliced in. Don't know. You can only try and see if it works. The worst that could happen is that you have to replace the card, and if its fried, then you have to replace it anyway.
 
umm what is PSU molex connector?

there is only one single place in all computer where i can plug in the cable that is coming from my card. And that is where it has been plugged in for 2 years.

Too bad i cant get to ampermeter really... and even if i could, how would i test the volatege? the cables are not exposed anywhere so i cant have direct contact.

Also, the fan is spinning when i start my computer, so the fan is getting the power it needs to spin! But that could be coming from the AGP slot ... i dont know...
 
A molex connector is a plastic piece with 4 wires coming out of it. It carries the power from your power supply to the card, clipping into a socket on the card. That's what I was refering to. The socket on the card should have a spring clip that needs to be pressed so that the molex connector can be removed. If that socket has gotten so hot that the connector parts seem welded or glued together, then the card has definately overheated and is dead. The fact that the fan on the card spins confirms this idea. The power is coming into the card, but its just not getting to where its needed, the graphics processor itself.
 
Most 9800 PROs have a small cable that goes between the power supply and the card itself. If you don't have one of those, your power supply is connected directly into the 9800, and you're going to have to separate the ah heck to inspect it.
 
ok here is the thing... the plastic joining the cable to card is kinda darker on one side. this is the side that doesnt want to get disconnected. The other side i could pull out, but this side is kinda glued... like if the dark stuff there glued the plastic in place. I think you might be right that it is either corrosion or it was fried somehow or something. Ill definatelly need to get a new cable then.
 
Edited after second pic was posted:

The first picture looks normal. The plug pulls out to the right in that picture, the same way a similar power connector unplugs from a hard drive or CD ROM drive.

Hopefully your PSU has another one you can try in its place.

The second pic does look like it has some corrosion or scorching on it. If a different connector does not work, something on the card may have been fried.
 
Ok, lets try this step by step. If you still have the manual that came with your card, open it and follow along. There are two possible connectors listed, an NTSC for North America and a PAL for Europe. The PAL connector, as shown on page 10 (of my manual) is towards the front middle of the card, just ahead of the fan. Its a two wire connector. Underneath it should be a switch that must be pushed it using that connector. At the moment, I'm assuming you're in North America and so use the NTSC connector.

Pages 8 and 9 (of my manual) describe and show the molex connector and how to put it together. The molex connector is a four wire connector that plugs into the top back of the card and comes from the power supply. It may have a specific retention clip, though mine does not. On my 9800 Pro, the molex connector simply slides on and off. The female connector on the card should be white, or an off white. It is glued to the card itself.

You say that the plastic connector on your card is darker on one side than the other and is "kinda glued". That indicates a short and/or an overheat occured. My guess is that your card is dead, fried, however you want to describe it. Sorry about that, but it happens and there's not much to do except buy a new card. You might need to cut the molex connector wires and splice in a new connector as well.
 
Thanks guys... take a look at the last pic... i cant decide if its fried, or its some form of corrosion. But maybe not the whole card is lost, maybe i can just get a new plastic thingie there and replace it on that place. or connect the wires artificially and glue them somehow into the proper places

oooh man, i disconnected it after using a hammer. And this is definatelly not good,

You're right, the hammer wasn't good. The blackened pin shows something fried, so it probably doesn't matter. At least you have the connector out.

so do you think i can do it without buying new card? i mean... the card is alright maybe, its just that connector there is missed up. If i can bypass that and glue my cable to the right places ont he card i think i can do it. ah well, ill try my best, if not ill buy new card and power supply. ty

I meant that you have the connctor out, so it might be usable with something else, a new card for instance. With the connector out, either you won't have to splice in a new connector, or at least it will be a bit easier. You could try to put it back in and see if a connection is made, but I doubt that will happen. Do not glue anything!!! These things are meant to assemble and disasemble easily. Glue defeats the purpose. It might also melt cause a lot troubles on its own.
 
just to let you guys know, i just fixed it, thanks all for help you have provided. I had an extra cable, so i put it in... it didnt fit perfectly and it didnt completely slide in because the black rod gave too much resistance, so i used lots of duct tape to fix it there, touching the 4 contact points and it works 😀

So thanks for help, its a happy ending, for now, lol,
