Pc crushing while playing games

[galiber12]

Hello forums!

about 2 weeks ago while playing fifa 14 my computer crushed.
as a result I tried to find a solution.
first I tried to clean the computer from dust but it kept happening.
then I formatted my computer but again it kept happening.
so I checked my cpu temprature and it was 67, so I changed my thermal paste and now it doesn't go over 50 while playing games.
but it keeps crushing.
I ran a benchmark and it passed it here are the results:
now it doesn't crush while playing fifa but it crushes when im playing cod ghosts
