PC Shuts Off When Playing Game
Question: I just installed a realflight game and after it running for about a minute the computer completely shuts off can you tell how to correct this or what can cause this?
Answer:  Shutdowns 
can be caused by many things but since yours happens when you are 
playing a game leads me to think it may be an overheating issue or a 
video card issue. You should check your CPU temperature and fan speed to
 make sure it is not getting too hot. The fan may not be spinning fast 
enough to keep it cool. Take the cover off and make sure the processor 
fan is spinning and is free off dirt. You can also try to remove the 
heatsink from the processor and make sure there is a decent covering of 
thermal paste on the processor and make sure its not dried up. If you go
 into your BIOS you may have a section that will tell you your CPU speed
 and fan speed. Make sure they are within the limits of your processors 
specifications.
Another thing it may be is your video 
card. Is the game supported by your video card? If not that could be it 
right there. If it is you may want to update the driver from the 
manufacturer’s website.
                You should also check your Event Viewer logs to see if there  is any reference to the shutdown and what caused it.
