Hi
I've got a Packard Bell iMedia S2870.
It's a core i3 and does well but the graphics are quite poor. For Christmas I got a new Sapphire HD 7750 (low profile) but I can't disable the onboard graphics.
When I enter the BIOS the option is greyed out and as I move the the BIOS options it skips over the menu item. The motherboard is an ACER H61H2-AD and it has the latest BIOS firmware.
I'm basically stuck. Any ideas?
Thanks
Tom

did you install the graphics card and hook the monitor to it and boot up?

you don't need to disable the intergraded graphics. Just plug the gpu to the pci express slot, connect the dvi(or whatever else) to the gpu dvi slot, reboot, install the driver and you are ready to go. You must not install the gpu while the power cord is plugged on the wall

Is the new card installed when you try and disable the integrated? Usually installing a new card and hooking the monitor to it automatically disables the integrated.

I should have added..... but in my haste i forgot.
When i install the new card (I did try this) neither port displays anything. The onboard and the new PCI-E card are both blank, on both VGA and HDMI outputs.

Tried to do that but when I plug the new GPU in, nothing is displayed on the new or onboard outputs.
This is both VGA and HDMI. The only way the PC will boot up with any type of display is by removing the new card

Hi, First thing I tried was to install the new card. Then nothing would display on the new card or the onboard graphics.
So I took out the cards, went into the BIOS to try and disable but thats when I noticed it greyed out.
When the new card is in place, I can't get the monitor showing anything at all on VGA or on HDMI

Would it be possible to test the card in another system? There are many possibilities here. The card could be DOA, the OEM bios has disabled the use of a dedicated card, the board is limited to 25w on the pci-e port which isn't enough to run the card or the 220w psu doesn't have a big enough 12v rail to power the system with the 7750.

Thanks. Will try tomorrow on another PC. The 7750 is a low profile so thought it would be OK but you may be right.

OK, so I plugged the card into another PC (ASUS) with 350W psu. worked straight away.
so it's increasingly looking like the onboard 220w PSU is failing to deliver enough juice.
Next thing when I get time is to swap the PSU from the ASUS onto the Packard Bell and rule out the Motherboard simply refusing to play ball.
Thanks for the answers all, will revisit once i've had time to do some dismantling.
