This problem began yesterday. I noticed my CPU was at 90C constantly with very high CPU usage (>50%). I had no major programs running. I rebooted several times and the program persisted.
1. I went into safe mode and everything was normal. So this rules out hardware issues.
2. I reformatted and everything was normal..but then after installing these few programs, the problem began again.
-**** video converter
-Media player classic
-Microsoft Office 2010 Pro
-Weather watcher live
-Xiliosoft audio converter 6
-Malware bytes antimalware
-Aimersoft video converter
-Boilsoft video joiner
-daemon tools lite
-drivers for dell wifi, usb 3.0, graphics
3. I'm using a Dell Inspiron 14z

I'm seeing Weather Watcher do this! It's ww.exe in the process list. I just had a very odd thing happen in that the process list did not show much activity (it insisted 98% idle), but a monitoring program I use called performance monitor 4.x (by Lorenzi Davide, not microsoft's Perfmon) showed at least 50% constant CPU usage! Terminating weather watcher stopped the high usage immediately, and this is one of two of my computers on which this happens. I have a guess that weather watcher gets stuck on updating the weather info after the PC goes to sleep and awakes, but it's just a guess.
