Hi all, I'm justifying asking the forum because I'm currently in an introductory computational physics course that requires Mathematica, and I hope to soon start other computational work. My https://www.amazon.com/Lenovo-Y580-15-6-Inch-Laptop-Dawn/dp/B009AEPQDI's motherboard and hard drive are supposedly failing, but all I've noticed is minor excess heating and a clicking sound in the hard drive (which I know indicates failure, but it's been doing it for a while). I've cleaned it thoroughly and had it analyzed by several tech support departments and they've all recommended I simply purchase a new one. However I'd really rather avoid it financially, and the only performance issue I've noticed with it is an inability to play games from this decade at normal speed. It plays streaming video fine, and programs like Audacity and Codeblocks also have acceptable load time. Would replacing just the motherboard work? And if not, would a cheap $250 laptop replacement be acceptable at my level?
