Write down everything it says in the actual error code section
take a high rez photo and host it somewhere then link it here.
I need to know what that error screen says to the greatest extent possible.
The screen states : A problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time you’ve seen this stop error screen, restart the computer. If this screen appears again follow these steps: Check to make sure any new hardware or software is properly installed. If this is a new installation ask your hardware or software manufacturer for any windows updates you might need. If the problem continues, disable or remove any newly installed hardware or software. Disable bios memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select advance start up options and select safe mode.

I should add that this problem has only arisen since my son tried to install a trial version of windows8 on this computer
