I went to use my PC the other day and was running painfully slow. Checked the processes and saw CPU usage was at 100% but could not see where it was being used. I even expanded the list to show Microsoft processes. There is about 50% CPU usage missing from the list when it is pegged. I tried running in safe mode and still the same. Checked the physical memory and it checks out. Tried running anti-virus and malwarebytes and they picked up on nothing. I then backed up my data to an external drive and reloaded the PC back to factory image. It is still not any better. I left the external drive seperate so if any data was corrupt with a bug it would not affect the fresh load. CPU usage is still pegged with no indications of what is causing it. I even went into msconfig and dropped half of the list of bootup processes and still no joy. Your assistance would be greatly appreciated!! Thanks!!

Download Process Explorer: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx
Unzip ProcessExplorer.zip, and double click on procexp.exe to run the program.
Click on View > Select Colunms.
In addition to already pre-selected options, make sure, the Command Line is selected, and press OK.
Go File>Save As, and save the report as Procexp.txt.
