I was factory resetting my ASUS X550J, and during the process, I accidentally switched off the power. Now it just keep restarting the startup ASUS screen, what should I do?
The OS is probably corrupted then. You will need to reinstall the OS from scratch. In this case, you'll need to create a bootable USB/DVD (I suggest USB) using this tool: http://windows.microsoft.com/en-gb/windows-8/create-reset-refresh-media and boot from it on the laptop. Follow the installer through and delete any existing partitions when the installer asks and allow it to create the partitions that it needs.
