After a couple of months of battling with blue screens, I finally decided to wipe clean my girlfriend's computer. It had worked perfectly before.
It's a Asus Vivobook Q200E.
I tried to restore it by using the restore partition on the hard drive, and after following the simple instructions it started its thing. But after 10 minutes it got stucked at 'Resetting your PC (18%)'. It's been over two hours and no apparent change.
There's no sound coming from the PC, and the circle just keeps spinning. Any ideas how to solve this? Or get past this problem?

Method 1: Perform System Restore, from Windows recovery mode.
a) Insert Windows 8 installation media and restart the computer.
b) Press F12 key (typically this is F12, but it can differ between computer manufacturers) and choose the drive that you inserted the installation media into.
c) Once the Windows Setup window appears, follow these steps:
d) Click on Next and select Repair your computer.
e) You will then see a blue screen and an option to choose.
f) Choose the option Troubleshoot and select Advanced options.
g) Select Restore and follow the onscreen prompt.

For your reference: System Restore.
