Hello! My CPU is going up to 48 to 57 degrees celcius when playing games such as Watch_Dogs and Mortal Kombat X, which is either shutting down my computer or restarting. When it restarts it acts like the screen is going to sleep, then it does it's routine start up, and when it shuts down (Most of the time when overheating) it turns off then it won't turn on unless I switch the power supply switch off then on. I think what is happening with my computer is extremely weird because, I replaced the current CPU which is an AMD FX 8350, I replaced it with an old CPU I forgot the name of it about a month ago and didn't give me problems until now. I recently took off the heatsink and replaced the old thermal paste with newer thermal paste, I didn't put much just a little bit in the middle, I mounted the heatsink and it is still giving me the same temperatures and doing the same thing as in restarting/shutting down my PC. There is no dust in the heatsink, nor case I even cleaned it out with compressed air and didn't help. Someone please help me I can't play most of my games because of this problem.
