my pc is:
CPU: FX-8120 @ 3.1 /w stock cooler
VIDEO: HD7770 ghz edition sapphire
MOBO: Asus m5A78L-M/USB3
RAM: 1x4 gskill 1333mhz + 1x4 corsair vengeance LP 1600mhz
PSU: generic spektra 550W
well my problem is when i have the default configuration for the cpu i mean turbo core enable, c6 state enable, cool n quiet enable and q-fan enabled the cpu frquencies fluctuates too much when i play (example, playing league of legends at 60fps on a team fight it falls to 10fps from nothing) , so people told me that i need to desactivate all that things and the cpu still on 3.1ghz but the temperatures are too high (50°C idle - 65-70 on charge), but when i play or i really charge the cpu the frequency lows to 1.4ghz and then up to 3.1ghz and continue doing that.
i really tried everything i found on internet, they told me that the psu is the problem but i need a warrantied answer before please, maybe its a cpu problem.
i uploaded images from my bios and a stress test that i did.
