|"i figured it was overheating and i checked the cpu and it had little thermal paste on it so i put more on"|
It's only supposed to have a "little". My guess is it was OK, now there's too much. Did you completely wipe off the old stuff & then apply fresh paste? If not, that' s a mistake too. AMD CPUs use the "middle dot" method. Watch this video:
If you suspected overheating, all you needed to do was check the temperature reading in the BIOS or try using Temp Monitoring software.
