Why does my gaming laptop have constant fps Drops?

Lenovo Y70
Intel(R) Core(TM) i7-4710HQ CPU @2.50GHx(OVer glocked to 3.3)
Nvidia Graphics Card Geforce GTX 860m
Windows 8.1 64 bit

I have all the drivers install most recent.
The fps drops occur in everygame, note i'm not getting low fps. MY fps is 150 or lower all within playable range but then drops to 7 or 10 and then jumps back up. This is not a temp issue for the temp constantly stays below 50C. Any answer is helpful.

Well you could have a virus wheras i would sugest an AVG scan. Also though in a good temp make sure the fans are unblocked. It also could be from too much downloaded onto it wheras i would sugest at least free gigabyte for it to run properlyy. If these games are online it could be an issue with your internet which if so check settins and/or call your service provider. If it is oldre than 2010 it could just be aging depending on how much it is used. Also don't have to meny programs running at once as that will dropp fps signifently. Hope i helped.
