[Liondz]

 I have an HP laptop . When I am browsing or playing  the device lowers the processor speed to 0.79GHz and after a long time it returns to its speed. I tried all the solutions to address it and it didn't work.
Note: The temperature reaches 65°C and then decreases to 45/50°C
CPU: AMD E2-9000e RADEON R2, 4 CORES 2C + 2G computing
GPU: AMD Radeon (TM) R2 Graphics(80mb vram) 900Mhz speed
RAM: 4GB ddr4 1800Mhz 

my Mainboard hp 8330 version F.51 (2019) I update it from F.31 

any solutions to fix it ?
