So I wanted to upgrade my prebuilt pc ( 500-009c) is the model number. I was gonna put in a 750ti and 500w evga psu. What are the steps I need to do to upgrade, ik how handle the parts and stuff I just aren't sure what to do first. Maybe disable on board graphics and my old amd drivers b4 I start? Hopefully no bios things need to be done to make the card work. I've seen people use the same card on the same pc that said it worked for them so hopefully for me. I'm pretty sure the card will work cuz I've asked around a lot but I just don't know what to do first
