Question FPS Drops 10-60fps small stuttering during gaming, CPU temp/usage high

[trickz029]

if anyone can help fix this i'd be grateful, i have bought 16gb RAM and new fan to drop CPU temperatures and ensure airflow but it's still not fixed, i have updated my drivers, Reset my pc incase of viruses, made sure i applied right amount of thermal paste.No apps taking up CPU usage

SPECS:

Windows 10

Intel Core i5-3470

Intel DQ77MK

16GB RAM

NVIDIA GEFORCE GTX 1050Ti

Performance: (CSGO)

Cpu temperature sticks around 70-79'C

Cpu usage:usually around 70-80% but has reached 94%

fps AROUND 90-150 but can reach 180 but jumps random numbers
