Just bought a new graphics gard.

http://www.novatech.co.uk/products/components/amdradeongraphicscards/amdhd7750series/r7750-2gd3.html

Tried installing it in the following computer.

Pentium g840
Gigabyte B75M-D3V S1155 Intel B75 DDR3 mATX
http://www.dabs.com/products/gigabyte-b75m-d3v-s1155-intel-b75-ddr3-matx-8013.html
OCZ Technology ZS Series 550W 80+ Bronze Power Supply

When I turned the computer on everything comes on normally, the fan on the GPU starts to spin, but I get no display. Tried HDMI and DVI sockets. I've previously used an old Sapphire HD5770 with the computer with no problem and when I took out this new card out and replaced the HD5770 it worked again no problems.

I then tried installing the new 7750 on this computer on which I'm currently running a XFX 7770 with no problems. The new Asus 7750 worked this time with no problems

I5 750
Asrock P55M Pro
OCZ Technology ZS Series 550W 80+ Bronze Power Supply

Any ideas why it's not worked on the g840?

Are you sure you are plugging it into the correct port? Most cases have double ports and for me, the port on the bottom is the GPU. You should always make sure that you plug in your monitor to the GPU, otherwise your PC will try to run through the integrated graphics on your CPU, which will not happen, considering that your GPU is plugged in. Try plugging it into a different port is all I'm trying to say.

Hi,

Thanks for your reply. No I'm plugging it into the correct port.
