Hi all
Hopefully someone here can help me resolve an issue with a new Sapphire HD 4550 graphics card that I installed today on my Acer desktop. With the card in the PCIe slot, nothing happens. The fan on the card doesn't spin and the computer starts but doesn't sound like it is booting to Windows. Nothing comes up on the monitor so I can't access the BIOS.
I have managed to get Windows (Vista 32-bit) to recopgnise the card and install the drivers, but only if I set the BIOS to load the onboard graphics by default. If I then reset it to load the PCIe graphics card by default, the computer freezes on start-up and doesn't even reach the BIOS.
I am wondering how I can Disable the onboard graphics (Radeon X1260 on an Acer F690GVM motherboard) because this might be the problem. I tried to do it in Windows Device Manager, but it keeps coming back online. Any ideas?
My system has an AMD Athlon 64X2 dual core processor. The PCIe slot worked fine with the NVIDIA card that I tried in it recently (which I returned and replaced with the 4550).
I tried disabling the integrated graphics card and uninstalled the drivers before I installed the 4550 the first time. I have tried taking the card out and putting it back in. Nothing changed.
My PC has a 300 W power supply, which is what is recommended for the 4550.
Any ideas how I can get this card to work?
Many thanks!
