I have a old processor called : INTEL CORE i3 2350 CPU and I don't arrive to upgrade it. I try many things but It does'nt matter.
If someone can help me, I will be very happy.
Your options are limited. First, you must contact the manufacturer of your motherboard/system/laptop and ask what processors are compatible with their BIOS. Then, you can select from those processors.
An upgrade processor must be socket, bios, and chipset compatible.
