Toshiba Laptop Black Screen

When using my Toshiba laptop the screen went black for a few seconds, came back, the went black again permanently. I turned it off but when I turn it back on the Toshiba loud up screen comes on but the screen again goes black afterwards.

The solution of, 'turn it off, plug it out, take the battery out and hold the power button for a minutes', DOES NOT WORK!

I can start the laptop up in safe mode but I don't know how to troubleshoot the problem.

I have no problem in restoring the laptop but I can't afford to lose Microsoft Office.

The laptop operates on Windows 8.1 and I was using Chrome, Excel and Drivermax when it crashed. I thought Drivermax was the problem so I deleted the latest driver download from it and uninstalled Drivermax altogether but it didn't work.

Any help would be greatly appreciated.
