Games trouble

Hello , ok here's my problem:
I was playing some games on my pc two days ago and they worked perfectly , but now , when I try to play , after 3-10 min of game play , game freezes and I need to restart my pc , I tried to play few times , but everything was the same , after that I got temperature error , it shows that my pc temperature is high :

CPU temp reaches ~100C , when I opened my pc , every cooler was working fine and it was cool inside.
What may be the problem?

 

what cpu are you using? you should raise the speed of the cpu fan to 100%. also is it overclocked?

 

my CPU is Pentium IV , but how to understand overlocked? and how to raise fan speed?

 

just use speed fan to change all your fans to 100%. overclocking is a way to make your cpu faster. also open up your pc and see if your have alot of dust. that can cause you computer to overheat.

 

umm.. im a n00b but looking at your screenshot dont you think maybe fan 1 could be turned on tooo... i might be being a retard
