Started 3 days ago, I have brand new Lenovo 510 14 running an i3 6100u with 4g ddr4 ram but suddenly it has started making a 'brrrrrr' sound during playback, especially when using mouse and hovering over icons while watching videos, games work fine however (sims 4 runs fine). Ive reset this thing twice and ran every hardware test under the sun, one benchmark did show that the GPU was running slower than it should of been (intel hd 520). Any thoughts, thanks in advance.
