Windows 10: CPU's clock speed doesn't reach max when I'm playing a game but randomly reacher top speed...

Usually my cpu's clock speed never goes above 3.90GHz maybe 1 or 2 over but never gets to 4GHz even though i believ It's top speed is 4.20GHz I belive this is the second time it happened that i started my laptop and randomly the speed is above 4GHz and not going down, I had no games running nothing except when i went into processes i saw discord was running even though I closed it when it was strarting which was using 20% of the cpu, It doesn't make sense that when I'm playing games the cpu speed never reaches 4GHz and maybe discord caused it to go above 4GHz for some reason I need to some hel

CPU clock speed drops to 0.39ghz when playing any games

When I run any somewhat demanding games my CPU's clock speed drops to 0.39ghz or some insanely low clock speed and my fps fluctuates between like 1 and 140(mostly around 1-30 fps.) But this only happens when my laptop is plugged in, when the laptop is unplugged while running the same games, my fps is capped at 30 no matter what I do.

In this video you can see my fps fluctuate and how choppy the game is(top left): Video

Windows 11 CPU Clock Speed

Windows 11 CPU Clock Speed Very high 18227MHz all CPU Clock software showing high clock speed, on my asus OLED shows correct cpu clock.

 

CPU Clock speed locked at 0.79GHz

Hi, I have an i7-4500U CPU and for the last few months my system starts at full speed (2.39GHz) but as soon as the CPU goes below 30% utilisation after startup, the system locks the clock speed to 0.79GHz even when the fan is off. The CPU temperature is
around the 50degree C mark, therefore should be allowing the processor to go up to full clock speed.

I've changed the power settings to set the minimum clock speed to 50%, but that has made no difference.
