Hello. i have gotten a pc from a dads friend for free and it had really old parts in it like an intel Core i3-2100 and i wanted to play games with it so i bought myself a gtx 1050 ti. i have been playing some games with this potato pc for about 4 years now and i want to upgrade. i do not have a great budget since my dad doesnt wanna buy me a completely new pc. i wanted to ask if i could ONLY change my motherboard and my CPU and keep my old parts in and if that would even work. i dont even know where or how to start. ahhhh
