P7-1240/UEFI/GeForce GTX 750Ti

Hello,

 

I have a 2 year old P7-1240 ... it is running Windows 7.

 

I just tried to install a EVGA GEFORCE GTX 750Ti card in it.

 

Card fits fine and HP Screen comes up .... but then black screen when Windows tries to boot.

 

Pulling the card and going back to onboard video works fine.  I've done this numerous times.

 

From what I can see from talking with GeForce support, it appears to be either a BIOS issue or UEFI.

 

There does not seem to be a new version of the BIOS available under HP support.

 

Does the machine support UEFI?

 

When looking at Boot Order it would appear to, as it lists UEFI Boot sources.

 

Also in the BIOS there does not appear to be anyway to disable onboard video (as it is supposed to autodetect).

 

Card was new from the box so it is unlikely that it is defective (especially since it shows HP welcome/BIOS).

 

Help please, all ideas welcome!

JDWott, welcome to the forum.

 

The EVGA 700 series cards all require a UEFI BIOS on the motherboard.  Therefore, since your computer doesn't have one, the card will not work.

 

You said that you contacted GeForce support, was it EVGA Tech Support (1-888-881-3842)?  They are very good and will be able to tell you if there is a VBIOS update for the card that will allow it to run in your computer.  Tell them that you were advised by someone on HP Forums to contact them.

Actually it was nvidia/GeForce tech support.

 

They ultimately said it would be up to HP or EVGA to see if there was a solution.  But they were pretty sure that UEFI was required for the 700 Series.

 

My question would be why wouldn't a 2 year old machine have UEFI ... It appears that it at least partially supports it and if it was updated to Windows 8, wouldn't it need to support it?

Also, I believe this is a Jasmine motherboard which is supposed to be UEFI compatible?

"The Jasmine motherboard uses an AMI BIOS version 8 that is compatible with UEFI (Unified Extensible Firmware Interface)."

Thank you for the additional information.

 

Yes, it is a Jasmine motherboard.  However, I am not certain if this document is for your two year old computer.  I will ask someone at HP if it is or not and get back to you.  HP began introducing a full UEFI BIOS in mid-October, 2012.

So a Windows 8 upgrade isn't going to help?

This is correct.

 

However, here is a Software & driver download page from another model with the Jasmine motherboard that has UEFI diagnostics.  You should install it on your computer and run it.  This will help determine if there is UEFI.  Also, you can run CPU-Z to get further information.

Hi,

 

HP usually stops producing BIOS updates after one year from the model's initial release date which for your PC is May 2012.  You need a version 8 BIOS in other to get the EVGA 750 TI to work.  If you search the forum you will find many posts where many of the NVIDIA GTX 750 models have failed to owrk in PCs running a legacy BIOS ( not version 8).

 

The below NVIDIA GTX 750 models should work as these models will work in PCs that have a legacy BIOS or a UEFI BIOS.

 

MSI NVIDIA GTX N750 TI and the MSI GTX N750 TF

So I talked to the very useful person at EVGA.   He basically said no way ... the 700 series will not work with these machines.

 

However, he assured me that 600 series cards would work fine ... but a power supply upgrade would be required.

 

So like a good little consumer, off the the store I went ... returned the 750 and bought a new power supply (Corsair 500W) and Gigabyte Geforce GTX 660.  Which everyone at the store assured me would work fine.

 

New power supply installed no problem.

 

New card still won't work ... machine hangs at HP Startup screen.

 

Searched the Net and it still seems to be a HP BIOS issue.  Essentially all the fixes everyone seems to mention involve turning of onboard graphics or turning off secure boot ... Neither of which are accessible through HP BIOS.

 

Any other bright ideas?  Of course, Gigibbyte support is in Taiwan, which does me almost no good.

"any other bright ideas" sounds like you are mocking me.  This is not not forum etiquette.
