Do you overclock or something? If so then revert it please. And it can help when you disable the quickstart in Windows. If you have a SSD then the quickstart is basically useless because it does only slightly speed up the boot times. You can disable it with following steps:

1. Start cmd.exe with Administrator priviliges
2. Type following into the command line: powercfg /h off
3. Press Enter
4. Reboot the computer

Cheers
