Lenovo Y470 - burning smell followed by blue screen - small burn on motherboard. What do I do? So I was using my Lenovo y470 yesterday when I notice a burn smell, soon thereafter i get a blue screen of death, try a system restore but it won't start up. I opened it up and I can see a small burn spot on a motherboard component next to the fan. What can I do to fix this? Do I need a brand new motherboard? I'm at a loss.
