I'd restore it back to before all the beta.
Also, let's go over your 1st of the month canned air routine. This is not optional on gaming models.
I recently purchased an Asus gaming laptop, shes a beast and I've loved her up until she started acting up. Somewhere in between downloading the newest NVIDIA driver, downloading the battlefront beta and updating my laptop to windows 10 my laptop has run afowl with something; whenever I played an installed game like far cry 4 or crysis 3 the frames per seconds would go heartbreakingly slow. This is strange cuz I could have maxed out practically any game resolution wise and now even portal is slower than a snail on elephant tranquilizers. Ive tried scanning viruses, shes clean, ive checked all the resolutions on most of my games: golden. Idk what to do about this, im frustrated and im all out of ideas; any help would be great thanks guys and gals.
