So , i have a Asus X55V with windows 7. The Unit keept bluescreening so i reinstalled window 7 ultimate from a USB stick.All went fine ,i got to the part where it prepared for the first boot,then the unit stopped and it won't turn on,no lights, no power . Can you help please.Thanks
No power may mean that the motheboard failed, assuming your charger and/or battery are still working. If you are comfortable with getting inside the laptop, you can reseat the memory and try again (or leave the memory out when testing). It sounds, though, like a piece of hardware is going to need replaced.
