First thing to do on a Win 8 laptop is to burn your recovery discs or use a usb flash drive for your recovery to factory state program. If you haven't done your recovery to factory state (starting a again) then you need to do it now. Refreshing isn't a good option in my humble opinion as you lose all HP's programs but hopefully the restore to factory settings in the 'hidden' partition will still be available.
Reboot the lappy and keep tapping F11 key (not pressing) and you should get to the recovery manager screen. Follow instructions for what you need to do from there. If you successfuly restore to factory settings then create a recovery set of discs or flash usb recovery as soon as possible.
We can then look at your problem if it will still exist.
