My PC (Asus N-55SF) took a youthful as ever thanks to the SSD which for me is currently the best in the market being quite affordable taken in view of 500GB it offers. No startup recognition problem, it is as if this one was always was there! However, it will consider using the Crucial cloning software (Crucial Laptop Easy Installation Kit for Flash SSD 2.5 ") to make a clone of its HDD to SSD before changing one for another.
