Its a very serious problem, I bought a Nvidia Geforce GT 710 graphics card yesterday, and I pretty much didnt tested much of the requirements, I just saw its ddr3 and requires a pcie express 16 slot. When I inserted it into the slot and turned my PC on, it wasnt displaying anything, all that came was a "Power Saving Mode" msg on the Monitor and it turned off. I tried removing the new gpu and then turned on and the computer was on. I found that my PC was running an Integrated Intel 82945G graphics card. So I cant run both of them at the same time. I saw an option to disable the Integrated GPU from the Device Manager, but then again if I would disable it then my screen would turn black and then how can I activate my new GPU by installing drivers in it. Please help is there any way to fix this. I cant abandon my new GPU as it is very costly. Or is there any other problem? And one more question should my PC boot up even if there are two GPU's one integrated and one dedicated on it, if yes then is there any problem with the compatibility of my new GPU?
