Hi,
Thank you for posting your query. I understand that you're receiving Error Code 0xc000007b on your Windows 8 PC. We'll surely assist you regarding this.
Being a software engineer, I can tell you there are broadly two causes- there is a conflict in your operating system or application software (here, in this case, its FIFA 14), or there are hardware issues like new hardware is connected to your PC though we know this is not the case, by the way.
This guide shows how to verify problems with your computer's configurations, MBR, and so on.

1. Right click FIFA 14 Desktop icon, select Properties from context menu options.
2. This opens up Shortcut Properties dialog.
3. Click Compatibility tab.

5. In the drop-down box that enables, select an earlier version of Windows.
6. Click Apply, and then OK.
