945GCT-HM Motherboard does not recognise my Sapphire HD-7750 graphics card

YOU Can Visit The HP.com and go to support and downloads and put the model number which is 945GCT-HM and you will get the drivers just download the latest one available and done.

make sure the adapter is not damaged when it is plugged into the card.

The Motherboard is considered the 'Building Block' of the computer.

From it all hardware components are supported.

Processor, Ram Memory, Harddrive, Optical Drive/s, and add-on expansion slot cards.

A graphics card (Video Card) being one.

You need a graphics card that the ECS 945GCT-HM,
or also stated as HP's Livermore8-GL6; will support.

The motherboard chipset is an Intel 945GC,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_chipsets

According to Intel came out the first quarter of 2005,

http://ark.intel.com/products/34505/Intel-82945GC-Graphics-and-Memory-Controller

The year PCI Express 1.1 technology came out.
PCI Express 2.0 technology didn't come out until 2007,

http://en.wikipedia.org/wiki/PCI_Express#PCI_Express_1.1

Will the ECS 945GCT-HM support graphics cards based on the PCI Express 2.0 technology?

YES!

PCI Express 2.0 technology IS backward compatible, with PCI Express 1.1 technology.

You just won't get the full capability of the PCI Express graphics card; based on the PCI Express 2.0 technology.

Will you notice? Doubtful.

From what I have seen listed in reviews on the graphics card, I would not suggest a graphics card based on the PCI Express 2.1 technology.
Reviews suggest it doesn't 'play well' with a motherboard using the PCI Express 1.1 technology.

There is another thing to consider; Power Supply

Most decent graphics cards require a minimum Power Supply wattage, of 400 to 450 Watts.

This Power Supply requirement isn't just for the graphics card.
Graphics card manufacturers base it on a test computer system.
One they put together with a powerful Processor, high performance motherboard, 2GB's of Ram Memory (At least), optical drive/s, harddrive, and the graphics card. (Plus allowance for computer case fans, etc)

If you're running a 300 Watt power supply, this = No.

(Yes, even though AMD ATI Radeon graphics cards, are touted to use less power; 400 to 450 Watts is still the limit for a decent graphics card, from them. Unless you want to run a simpy PCI expansion slot graphics card, or budget/starter, PCI Express graphics card)

Yes provided the expansion slot on the motherboard can fit this graphics card. If your motherboard has a built-in graphics chip then you most likely need to disable the on-board graphics before installing this graphics card and driver..

You need to update the Bios to the latest version to recognize that cpu. You can get it here:
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=us&lc=en&dlc=en&softwareitem=pv-66825-1

once you insert the XFX readon hd5450 card into PCI E slot on the motherboard go into the bios by tapping DELETE key until you see bios options and then go to advanced Tab and check if primary video adapter is selected to on-board and if yes change the same to PCI-E save the settings by selecting exit tab and then select exit saving changes and save and restart. I am sure it should then detect the graphic card and you can then plug in the monitor to the VGA slot on the Graphic card.
do reply if you need any more help Good luck.

Hi,

Your motherboard has an an AGP 4x slot.

AGP is an older technology now and has been superseded by PCI-Express graphics.

The best AGP card you can get would be something like this:

http://www.play.com/PC/PCs/4-/5416296/Sapphire-ATI-Radeon-HD-3850-512MB-DDR3-AGP-8X-Graphics-Card/Product.html

It is more than powerful enough for HD video and also has good 3D graphics performance.

Please rate my answer if this helps.

Many thanks,

Chris

Hi, Before doing anything please refer the motherboard manual, and as per my knowledge you need not solder any pin on the board, if you do so may be something else might not work. I better suggest you to check the Manual before doing anything.
Regards

Yes, it should work ok.. Your motherboard supports 1 x AGP8X, and since this card is 8x AGP, and includes a power adapter cable, it should be fine. Just make sure you have an adequate power supply (400watt+)...

I have a Sapphire X550 512 MB HM Pci-Express Card. But i lost my driver CD. So i want its driver for windows XP-SP2. So how can i find this driver.
