[SOLVED] CPU stuck at minimum clock speed

[Androoi]

Hello guys! As the title states, I have a problem with my CPU (i5 6402p) permanently running at it's lowest clock speed (2.81 GHz) even if the utilization might be at 100%. I have tried changing the power settings in the control panel but with no succes. Thing is, the minimum and maximum CPU state settings in there are missing. The temps are not getting too high (CPU-Z benchmark) so I asume it's not a thermal throttle issue. Let me know if you need any screenshots or info. Thanks!

Is this in a prebuilt system like HP or Dell?

Yes, it is. Do you think it could be a PSU issue? I mean, it's been working well the past few years and I recently noticed this issue.

Reinstalling the OS partially solved the issue. Now, the clock speeds do go higher but are bound to the clock ratio, they no longer fluctuate depending on CPU strain. Also, the CPU doesn't seem to go any higher than 3200MHz even though the ratio is set to maximum (34).
