New graphics card no display

[mattzx]

Just bought a new graphics gard.

amdhd7750series

Tried installing it in the following computer.

Pentium g840
Gigabyte B75M-D3V S1155 Intel B75 DDR3 mATX

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 MSI 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?

Maybe the bios needs updating or try the 7770 in the 840 system to see if it runs.
7750 ddr3 must be pretty pants compared to a 5770 though

Yeah, sorry I realized that after I posted. Do you have a solution or did you just come onto the thread to tell me that?

The bios is upto date both the 5770 & 7770 work in the 840 system. The 5770 is going to be used elsewhere.
