100% CPU usage when Gaming Tags: CPUs Games Last response: August 14, 2012 1:16 PM in CPUs Share 23dexter89 August 14, 2012 4:26:55 AM Hi Guys. I have a simple question. What could cause a CPU to goto 100% usage when running a video game? The System is as follows: Intel Core i5 760 2.8GHz EVGA GTX 460 SC EE 8GB GSkill DDR3 Intel P55WB Mother Board In Win 750w PSU The Game is Battlefield 3 Could any of the following cause this? - Bad CPU Cooling - Bad Internet connection - Dust The Game worked fine for more than six months. I started to get Low FPS with Very High CPU usage since 3 days ago. I haven't done any new hardware or software changes. Today I did a fresh install of windows, Updated the Graphics card Drivers and repair installed the Game as well. But the Issue still Stands. Any Advice??? Thanks in Advance.

Also I just installed CPUID Hardware Monitor, and according to it, the core temperatures for my CPU are in the low 70's Celsius. Is this Normal? (I'm from Sri Lanka so It's naturally hot here.)
