Computer Shuts Down When I Run Certain Applications

Question

Whenever I try to do things such as play games on Steam, my toshiba Satellite C855-S5350 shuts down after 10-15 minutes of playing. It doesn't just turn off the display: it shuts down and I have to start everything up again. My computer's fan starts going
crazy just before it shuts down, but the computer is not hot to the touch.  I have windows 8. I went on the event logs and found this at the exact time of shutdowns:

Please provide us with your Event Viewer administrative logs by following these steps:
Click Start Menu
Type eventvwr into Search programs and files (do not hit enter)
Right click eventvwr.exe and click Run as administrator
Expand Custom Views
Click Administrative Events
Right click Administrative Events
Save all Events in Custom View As...
Save them in a folder where you will remember which folder and save as Errors.evtx
Go to where you saved Errors.evtx
Right click Errors.evtx -> send to -> compressed (zipped) folder
Upload the .zip file to skydrive or a file sharing service and put a link to it in your next post
If you have updated to win 8.1 and you get the error message "the system cannot find the file specified" it is a known problem.  The
work around is to edit the registry.  If you are not comfortable doing this DONT.  If you are, backup the key before you do
Press Win+"R" and input regedit
Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Channels. Delete "Microsoft-Windows-DxpTaskRingtone/Analytic"
