Hi,
Please do try these troubleshooting steps that may help.
- First is to do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting up again.
- If the same problem will persist do try loading the laptop in Safe Mode.
- While the laptop is booting up, repeatedly press on F8 until it loads Advanced Boot Options then select Safe Mode.
- If Safe Mode will load do run System Restore to bring it back to an earlier date or time when everything was working fine.
- Here's how to run System Restore:

- If System Restore will also not load, your last option would be to reinstall Windows 8.
