i am having issues installing the mentioned gpu. i am replacing the 4650 with the 6870. i but it in the computer, and when i turn t on, i hear the fans of the gpu running very load (i have the dual-fan edition). however, i get no response from the monitors. when i connect one of the monitors into the integrated graphics, the monitor works fine. i searched this problem, and it said i needed to disable onboard graphics. so i ran windows 7 through onboard graphics and disables it via the device manager. when i restarted still the fans for the gpu were running very loud, but i got no response. i plug the monitor into the onboard graphics and it works fine but it automatically goes into a much lower resolution. when i put the disc for the gpu driver in, it doesnt recognize the gpu. this makes me think i installed it incorrectly, however it seems like it is installed correctly because the fans are working on the gpu.
i have the GIGABYTE GA-880GM-USB3 AM3+ AMD 880G USB 3.0 HDMI Micro ATX AMD Motherboard
p.s i cant find how to disable onboard graphics from the BIOS, under "integrated peripherals", there is nothing about the graphics
p.s.s i have a 750 w psu so the power is not an issue
thank you so much for your help
