My PC, a Dell Optiplex GX280 (old but is meeting my needs) running Windows 7 Home, and using the Windows Task Manager, shows that lately the CPU is always running at 100%. Looking thorough the Task Manager, it doesn't show anything using a lot of CPU resources. When Firefox is running it is the highest at about 10%. When I start the PC in Safe mode, the CPU usage only shows about 27%. If I'm correct, Safe mode doesn't load all of the drivers. Could this mean one of my drivers is at fault? I haven't installed any new programs lately, just the usual updates from Microsoft, Nortons, Flash player and Java.
I've used Microsoft's Windows Sysinternals, Process Activity Summary, but I don't really see anything that should be loading the CPU. The process svchost.exe > PID 1432, is showing some activity, but not a lot? Is there a better program out there that can help me find out what is going on?
