This computer is getting horrible performance. Nothing is running on it and 60% of both CPUs are in use. There are a few more processes on the list that I deleted before writing them down below. I’ll add them if I continue to have problems. I may just go back if I ever have the time and delete everything imaginable because I don’t like seeing the computer busy at 15 to 20% when nothing is going on.
atieclxx.exe The atieclxx.exe is a program of ATi Graphic card drivers. The function of atieclxx.exe is to give ATi Graphic card better performance so it just plays a subsidiary role. The MD5 of atieclxx.exe is 46b175d56d7235d700394ed99050617f and please be alert if its MD5 has been changed (viruses/spywares may also confuse you by using the name atieclxx.exe). Tried to delete it but access is denied.
ccc.exe CCC stands for Catalyst Control Center, and it’s part of your ATI video card driver package—or to be more specific, it’s part of the utilities bundled along with the drivers, and adds features like customizing your display, or setting hotkeys for different display profiles. As long as the ccc.exe utility is installed into your Program Files\ATI Technology directory, it’s a legit process that can be left alone. Deleted it with no problems, everything still works, cpus still at 60%.
ccsvchst.exe*32 The ccsvchst.exe file is automatically added to your computer upon installing the Norton software, and it is referred to as the Symantec Service Framework.

dwm.exe One of the new features in Windows Vista/7 is the Desktop Window Manager (DWM). It responsible for the graphical effects such as live window previews and a glass-like frame around windows (Aero Glass), without draining your CPU. A DWM-capable graphics card is required to enable the 3D effects, as well as Aero Glass. (In older Windows Vista Beta versions, the DWM effects are controlled by the User Experience Session Management Service, via “uxss.exe”.) You can increase your computer’s performance if you switch to Classic Mode (turn off Aero Glass and Animations), or reduce your screen resolution. 
explorer.exe This is the user shell, which we see as the familiar taskbar, desktop, and other user interface features. This process isn’t as vital to the running of Windows as you might expect, and can be stopped (and restarted) from Task Manager, usually with no negative side effects on other applications.

taskhost.exe And I think I have it narrowed down to the Windows RAC task… This after installing (and buying a few) multiple spyware and antivirus tools… I wonder if I should ask for reimbursement?? Anyway – my cpu was being consumed by the Windows Reliability Analysis Task – the way that I narrowed it down to this was by installing process explorer and letting it show me what was actually running under taskhost.exeI then went into scheduled tasks and stopped the reliability analysis scheduled activity - and presto the taskhost.exe went away and processor utilization shot down to essentially nothing Anyway – that seemed to help me… maybe it will help you Not sure why it is trying to burn up so much cpu… Based on the above comments I went to the control panel, selected system, then scheduled tasks, then disabled everything that didn’t seem necessary before rebooting. Now the system is at 15%.
