To save you a click: The company in question is Lenovo; they sold a prebuilt desktop with a motherboard that ended up not supporting nVidia driver updates for the GPU. Now anyone with this desktop is stuck on an old driver version and their computer crashes a lot, and can't play games as they become incompatible with the installed driver version.
Editorial by me: The only real solution would be to upgrade the motherboard which is at least a few hundred bucks; they may need to buy a new CPU or RAM as well, depending on what else Lenovo cheaped out on, and labour which the owner may not have the skill for, meaning even more money.
