After i have my computer turned on for a while it starts lagging really much, both in games bot also when idling. I found it pretty weird because the whole computer is only 1 year old. Then i used CPU-Z and when the lags starts, i discovered that my CPU core speed drops from 3.500 MHz to 800 MHz, also core voltage drops from 1.000V to 0.700V. Why does this happen? And how can this be fixed?
