Solved nVIDIA GeForce 7950 GT Possible Incompatability Issue

July 12, 2012 at 14:04:18
Specs: XP Pro SP3 , P4 3.2 Ghz 2 GB RAM
I'm still using XP with an old rig and thought I'd try to get a little bit more oompf out of it by adding a better grade of video card. I bought a new old-stock nVIDIA GeForce 7950 GT AGP card but when I plug it in absolutely nothing happens on-screen. No POST, no nuttin'. Yep power supply is on. Yep, I tried reseating it several times and rechecked all connection. The motherboard is probably incompatible. It's a lower tier Biostar u8788. Could someone in the know verify the incompatibility? I would have thought an AGP slot would take an AGP card: end of story. Obviously not.

I'm not completely opposed to replacing the mobo but then I'll have to get a new old copy of XP as a new mobo will void the OEM license of the OS. Sigh! If I move to Win 7 the AGP card I just bought then becomes useless. I'd kind of like to avoid all these additional expenses as I just very reluctantly laid out a lot of money for Mac equipment for authoring iBooks. Any insights into getting past this dilemma would be appreciated.

✔ Best Answer
Do you have an adequate power supply?

I'm with riider. if the machine is that old as to use AGP, it probably has an underpowered PSU too.

That's interesting. Actually the PSU is probably the best component in the box. I think it's an Enermax 650 or 700 watt. I may have the output turned down a bit so I'll check that angle. I also have another top notch PSU, brand new, in the box, so I'll try switching that out. So if I read you guys correctly, if everything else is working fine the AGP card should work on this [or any?] AGP motherboard? Could you verify that?

I noticed some discussions about a sister card that had issues related to something called SIL. I have no idea what that could mean but I gather those issues aren't related to this card.

It should work with that psu. The mobo shouldn't matter. It's not SIL, it's SLI and that doesn't concern you and this situation.

Thanx Riider & Grasshopper:

The PSU onboard was an Enermax but only 370 watts [I think I'm overdue for a memory upgrade myself] so I switched it out with a brand new Asus Earthwatts 650 Watts and still there's no action from the monitor when I fire it up. I tried the card in my wife's neolithic P4 [Intel D865 PERL; 650 watt PSU] with identical results; boot up doesn't even seem to proceed.

Is it fair to conclude that the card itself might be hooped?

I thought I might have to install drivers in advance of the hardware but that doesn't seem to be it.

It seems the card may be fizzed. You only install drivers after the installation is successful.

If you look closely you'll see the egg on my face. You guys were right, it was a power issue. The card wouldn't power up because SOME IDIOT NEGLECTED TO PLUG THE MOLEX CONNECTOR IN!!! That would be me. Doh! In my defense, I've never had a card that required a separate power source. Well, what a dummy! Thanks for your help, the card is working fine now that it has power. All the best
