Laptop freezes every 30 mins or so and needs to manually reset the power button

[Andreval]

I have an acer laptop (windows 8.1) and I noticed that every 30 mins or so it freezes. The mouse is still functional but the keyboard and the programs are not responding that i have to manually reset and use the the power button. I have tried PC fixer softwares like AVG tune up and system mechanic but still nothing changed. I tried to restart my laptop in safe mode and the freezing problem did not occur, i tried it several times.
I have my event logs here but i don't know what to look for.
Other people suggested i should do a SFC but the problem is, my laptop would not last longer than 30 mins and then will freeze and scanning takes so much more than 30 mins
Any problems that i might be having? I need help asap

That was the scariest event log iv seen in some time. It's eater a serious heat problem or a serious virus problem. I would start by doing a complete reset of windows or atleast a refresh. If the problem persist i would start looking at fans then check the psu for power problems.
