Thinkcentre E73 10DS not recognising gfx card Geforce GT 740

2016-11-04, 10:56 AM

Hi all,

 

Hoping one or two of you may have come across this before and be able to offer a simple solution as I have 20 plus of these to install once / if we can get the test PC working!

 

We have a mix of Lenovo desktops but to keep things simple let's concentrate on the E73 as above.

 

I want to install a GFX card capable of powering 3  monitors simultaneously (without VGA) and I am trialling the Nvidia Geforce GT740 (1024MB) as a possible gfx card to do the job.

 

However, after install the GT740 does not show in device manager even after a scan for changes'. All I am presented with is the standard on board gfx option. I have even tried disabling this but still the GT740 is not detected.

 

I have tried with the latest drivers from Nvidia and everpy time I am presented with the message:

 

"NVIDIA Installer Cannot Continue"

 

"The graphics driver could not find compatible graphics hardware"

 

The card is powered as the fan is on but I am feeding no further power to it from the PSU (which I assume should not be needed anyway).

 

This error seems to crop up a lot for various Nvidia GT xxx cards I have noticed through my searches but I've yet to find a definitive solution.

 

Any suggestions greatly appreciated.

 

Thanks in advance ... 

 

 

Solved! See the solution

I took a look at the Nvidia driver readmes on your system's Lenovo support page, and the Win 7/8 driver readme has a list of supported adapters, the Gt 740 is not on it, but a good number of other Nvidia cards are.

Thanks BiggAl, I see the gfx card is not officially supported for the E73 but wondered if there may be a compatible driver.

 

This looks promising for instance:

Will try some of those when I get the chance - unless I'm wasting my time?
