My wife has a HP Pavilion g6 laptaop machine. Working fine yesterday and shut down normally. This morning, won't start, blue screen, apart from the usual clunk or click from the removable optical drive, nothing, no sounds no reactions. I'm guessing it's disk has died, but am open to alyernative suggestions. Assuming the disk is the problem, can I fit a normal SSD in the thing? I've never worked on laptops before hence my question.
