This is the first time in 2 years I've gotten this problem. So basically, after about 10 minutes of the PC startup, my cpu speed goes from 2.5 GHz to 0.22 even though I have no apps open. For some reason, everytime I put my pc to sleep mode, it goes back to regular speed for a few minutes then goes back to 0.22 GHz. 
- I already set my maximum processor speed to 100%
- Put high performmance mode in power settings
- Put intelppm value to 1
Does anyone know a fix to this problem?

    Hi,
    Give this a try, turn off the laptop and disconnect AC adapter, remove the battery, press power button few times to drain any residual electricity, leave the laptop to rest for a while, reconnect AC adapter and boot the laptop, work as normal for few hours, then reinsert the battery and see whether it fixes the problem.
    Could you please post the full model name of the laptop and the OS.

    My apologies, go to BIOS screen and move to Main tab, press F9 button, then press F10 to save & exit.

    Your CPU is overheating. You may need to open the back panel and check the heatsink for dust etc and make sure the fan works. If you check both of those and still have the issue you will need to check the thermal paste on the CPU. It goes between the heatsink and CPU and I do not recommend this unless you are totally comfortable with taking things apart. On second thought, even getting the panel off these AiOs can be a pain… Be careful in both cases.

    If not an overheating issue, it's just likely7 that the load on the CPU is so low that it drops back to minimum speed to save on power. That is normal behavior and the CPU should speed up when more power is needed.
