When you first setup your computer you should have created your personal HP Recovery Media. If you didn't create this media, please do so at this time or contact official HP Customer Support in your region / country, via the HP Worldwide Support Portal, to see if HP Recovery Media is available for your computer. This media is essential in returning your computer to a factory like state when your hard drive fails, an update / upgrade goes wrong, etc.
It appears that most, if not all, WIndows 8.1 drivers for your computer were updated and available on the HP ENVY 17-j013cl Notebook PC Drivers page as of 9/30/2013. Downloading and installing these drivers should resolve your issues.
If you have any further questions, please don't hesitate to ask.
