The graphics chip on my motherboard no work

[Acolyte]

The graphics on my HP PC no longer works.  Can I install a PCI Express graphics adapter on the motherboard?

Your 300 watt power supply should easily handle an RX-560 or GTX 1050 TI.  Unless I am mistaken, neither of those graphic cards require a power cable.   I suspect your 300 watt supply does not come with even a 6 pin PCIe connector.

The problem is that currently those (entry level) graphics boards are way overpriced due to miners buying up inventory and lack of production in china.  The windows 10 drivers are better than the 7 you are running.

I would try to get your graphics working and upgrade to windows 10. 

What is the problem with the graphics?

Hi Beemer, thanks for your reply to my question.  You haven't answered my question.  As I stated the graphics chip on the motherboard no workie.  There is no signal coming out of any of the outputs to my monitor.  All of the outputs, VGA and etc., worked up until recently.  I've tried to replace graphics adapters on other HP PC's and it didn't work.  It seems some HP computers will only work with certain graphics adapters, namely the ones they install in the computer.  If you know the answer to my question, then please advise.

OK, I think I have got an answer and you are probably not going to like it.  After reading this old post over at Tom's Hardware it appears your system behaves just like my HP Pro3400 or cupertino2 motherboard.  

It will work only with legacy BIOS. Graphic cards 2012 or later have UEFI bios and are not compatible with your (or my) old motherboard.

I was able to get an S9000 to work in the x16 slot.  The S9000 is based on ATI's HD7950 but has only a single 8 pin power connector instead of 6+6 or 8+6 like some HD7950.  At the time I got my S9000 it was in the $100 range.  They are no-where near that now.  Your 300 watt will not work.

There is a report of a GT 730 "sort of" working here

Was the BIOS ever updated?  Do you remember the version number?  Without video is is difficult to upgrade the bios. 

You mention VGA but your motherboard has only a pair of DVI.  Were you using an adapter DVI -> VGA?  I once had a damaged pin in a cable and in another instance a pin was pushed back so far it no longer made contact..  Check your adapter or your cable.

Good Luck!

I will try to keep it simple
On the one hand indeed, if you do not have a uefi type bios, it is practically impossible to use a GTX 1050 type card.
But above all
you think that the integrated video, does not work because you do not have a graphic signal on the screen ...
Even if you install a graphics card, the result may be the same, because in fact the computer does not start correctly ...
Can you describe how it happened ..
What exactly happens after pressing the power button?
Do you see, for example, among other things, the HDD indicator light if there is one working, a different behavior of the fans etc?

Thanks for your reply.  My motherboard is the MSI MS-7778 (Jasmine), vintage ~approx 2010.  HP's specs on the web claims that a PCI Express x 16 graphics adapter is supported, but gives no further details.  I think you're right about the legacy BIOS.  The newer graphics boards have the UEFI BIOS.  I ran into this problem previously with another vintage HP Pavilion.  The graphics went out and I replaced the original adapter with a newer PCI Express x 16 board.  The system didn't recognize the board.  I found a board exactly like mine on Ebay.  I plugged it in and it worked.  I'm sure the issue is in the legacy BIOS vs. UEFI BIOS.

I don't have an application for high end graphics.  I just want Windows to boot so I can run business programs.  The GT 730  may work for me.  It appears to be a legacy BIOS graphics board and nothing special.  The link you provided regarding the GT 730 said the GT 730 2gb ddr3 GPU works correctly with a HP Pavilion p7-1297c , which is what I have.  Best Buy carries this board in the PNY GForce brand, so I'll test it out and let you know if it works.

Let me answer your questions.

1.  I never updated the system BIOS, it has the original version.

2.  I don't know the BIOS version.

The Jasmine motherboard in my machine has a DVI and VGA video output.  Both outputs don't have any signals.  I've eliminated the possibility of bad cables for both outputs.  The graphics in my machine have been flaky from the start.  I've suspected a graphics chip problem for some time now.  I'll be happy to bypass the graphics on the motherboard and go with a PCI Express x 16 2.0 graphics adapter, like the GT 730, if it works.

I'm much obliged for your insight and help with this problem.  You've given me some hope that I can bypass the graphics chip on my motherboard.  I'll continue to work on it.

Have a good day............Ralph

Hi Promethee,

We're in agreement.  The GTX 1050 board is a PCIx 3.0 interface and my machine is too old to support it.  I'm thinking that an older 2.0 interface might work with my legacy BIOS.

My monitor will tell me if there is a signal on either the DVI or VGA port.  Without any signal, you don't get much.  Windows won't boot.  As I recall, I got a blank black screen.

I've had spurious graphics problems from the start with my HP 1297c going back to 2010.  A hard reset got me back to Windows.  My suspicion was that the GPU was getting hot, it doesn't have a fan.

After pressing the power switch, the system indicates HDD activity, as well as all fan activity.  Frankly, I don't suspect any power supply issues, although erratic power supply issues may have contributed to the graphics chip failure.  You are right to say a graphics card may give me the same result due to a flaky power supply.

My current thinking is that a legacy PCIx 2.0 graphics adapter, like the GTX 730, might work.  I'll let you know.

Thanks for chiming in on my problem.

No, I rather had the idea of a defective motherboard ...
The activity, probable of the hard disk, could, indicate that this is not the case
I guess you have already tested ..
If you try to open the bios, and it works you may just have a problem on windows
If the bios, can not be displayed either, it is more a hardware problem
Now if you can test with a compatible card and not too expensive, try you will be fixed

"The GTX 1050 board is a PCIx 3.0 interface and my machine is too old to support it. I'm thinking that an older 2.0 interface might work with my legacy BIOS."

not exactly, you can use pci 3.0 graphics card with pci 2.0, it can work
The problem with newer cards is that for the most part, they don't work if the bios is not UEFI.
There is no version, proposed, if I have seen correctly, from the product page, so if you cannot see it yourself, for the moment it is still only a guess

if we look here, same motherboard
bios, obviously uefi
So it remains a possibility

Hello Promethee,

I may have a bad motherboard (Jasmine).  I don't know how to sort that out.  My plan is to add a PNY GTX710 PCIx  2.0 graphics board into my PCIx-16 slot.  If Windows 7 boots, then I'm good to go.  If it no boot, then I throw my hands in the air, return the PNY GTX710 board to Best Buy, and throw my HP Pavilion 1297c into the Manatee River outside my house.

It wasn't that long ago that Windows was the original "plug and play" OS from Microsoft.  There is no more concept of an Open System with Windows.  Windows has surrendered to Apple, the original Closed Systems manufacturer.  I will now refer to my HP Pavilion as an iPavilion.

Thanks for your help.  I think I may have reached an unsolvable problem with my HP Pavilion.  Without a UEFI BIOS, there's not much I can do with my HP Pavilion 1297c to get my graphics back.  My machine has suffered a fatal shot to the head.
