I upgraded my gpu; gddr3 Gigabyte ati radeon hd 4850 which uses PCI E *16 2.0 to a gddr5 galaxy gtx465 which uses also PCI E *16. As the new gpu requires a higher power, i replace my old psu to a new one which give more power than the new gpu needs.
But Here is the problem. I'm using 2 monitors, and the monitors works fine with my old gpu, but not the new gpu. The monitors don't receive any signal from the new gpu, so the monitors show no HDMI thing, but I do hear Windows starting sound.
So, i asked this situation to the galaxytech. They suggested disabling my old gpu driver and set the new one so that the new gpu is recognized. That didn't work. Also, they asked me to use Sweeper which is a software that uninstalls video drivers and their registry in the pc. I did it too. That didn't solve the problem.
What do you think the probelm is?
I guess the new gpu might be faulty, or i can't use gddr5 gpu on my pc. Help me guys.
