Hello,

So me and my friend bought the same custom build PC's with specs:

MSI 970A-G43 PLUS
AMD FX-6300
Asus Pheonix Geforce gtx1050ti
Forton 450w PSU
8GB Dual channel Samsung RAM 1600mhz (yay:D)

Later on, I decided to overclock my CPU, I bought Cooler Master 212 Evo.
I overclocked to 4.2ghz, watched a tutorial for correct overclocking and played CS:GO.
The temps were 60-67 degrees... I tought that was normal and continued playing.
Later my friend asked me to apply the same cooler for him too.
His temps were 40 degrees... I was really confused! It did not make sense to me.
Anyone know why? But that's not it!:??:

Later I figured out my temps were too high and I reduced my OC to 4.1ghz and started testing.. but all of sudden my pc started crashing... Getting blue screens on startup, not booting until I put the OC to 4ghz..... When stress testing, I got a weird sound from CPU, when it crashed, it showed something that the CPU did not get response from cores in time. But the temps were 40 degrees! I reseted my CMOS and it was working perfectly! Tried to do the OC to 4.2ghz but started crashing again :(
Now i'm at 4ghz, playing CS:GO and getting crashes sometimes.

Please help! i think that i fried my CPU :/
