Grinding audio/video lag during video games (CPU related?)

GenericName

TS Rookie
Hi, my relatively new "HP ENVY TouchSmart m7 Notebook PC" has been having crippling lag while playing video games. The lag slows the computer down to about 0.2-0.5 frames per second, and slows the audio down to match the video speed (which produces a grinding sound). This lag happens every 10-45 seconds depending on how long the computer has been running. Some help would be appreciated.

What antivirus program are you using? Is the notebook fully updated using Windows Update? Are you running Windows 8.1?

Damn, sorry for the late reply. I've been busy with school lately. Anyway I have Webroot SecureAnywhere, the Notebook is fully updated, and I do have Windows 8.1. The problem still existed before I had 8.1 though
