my desktop specs are:

Intel i7 - 4.0 Ghz
Ram 16 Gigs
Nvidia GTX 660 at 4 Gigs
Windows 7
Over 500 Gigs of free space

What happens is I would be playing a game like Black Ops 3, everything would be fine, but then suddenly it become super slow.

I check if it's a heating problem but there the heat monitors showed no irregularities.
the system requirements for the game clearly state I'm in the clear and I have all the drivers and updates from Nvidia installed. I have to restart the pc every time so that the game functions at normal speed...It's also not a CPU problem as usage doesn't rise over 25%

Please help.

Thank you
