I have a Dell Inspiron 7567 (gaming) and I've been recently having issues with the CPU appearing to throttle while i try playing games. Though it says nothing in task manager, in XTU I can see that the package tdp will drop from ~20W to around 5W, the processor cache frequency dropps to around 0.9GHz from the usual 3.0+ and the utilization spikes to close to 100% (despite showing low in task manager). There's no obvious reason for this, I've had the computer for almost 2 years, and this is a new issue. The temps aren't high (65ish, and it seems that the temp is actually slightly higher while running well than when running poorly). I have tried a ton of things, including underclocking both cpu and gpu, checking for viruses, checking background processes, checking power settings, updating drivers and bios, and checking the cpu itself in hardware scans. Please, someone help me. It's incredibly frustrating to have a gaming laptop i can't game on.
