>A friend had his laptop's chipset reballed there Sounds like he got scammed. Reballing only is a temporary few months at the most fix. Its not the pcb-bga contact that fails, its the silicon-bga package that has the problem. Reballing heats up whole chip and by accident reseals broken solder joints directly under the silicon. Those joints will crack again because NVIDIA used bad glue that gets plastic under heat stress. The only way to fix bad Nvidia GPU is to replace it with a brand new one from the fixed batch with new glue formula. https://www.youtube.com/watch?v=VjmBv6nvUOM https://www.youtube.com/watch?v=VjmBv6nvUOM
