Hello, I'm trying to upgrade ONE of my computers with possibly using component from another older computer. The ONE I'm trying to upgrade as an AMD processor. I read on several posts that I cannot use the AMD motherboard to intall an Intel processor. IF SO, can I take the Intel motherboard from my old computer, swap it with the ONE computer's AMD motherboard, AND install an upgraded Intel i5 processor? I've researched upgrading graphics card and will be adding more RAM since it's currently 3 GB. Thank you!
