In Task Manager, System, not System Idle is running at 97-100% at all times

Computer is running extremely slow. Task manager shows "System", NOT "System Idle", to be using 97-100%. No other processes are running. Has been going on for about a week. Have updated MSSecurity Essentials and ran full scan, 0 found. Updated and ran Malwarebytes (took 16 hours!!), 0 found. Ran disk cleaner. No improvement. Ran defrag (took all day), no improvement. Uninstalled unused programs. No improvement. Ran CCleaner. No improvement. Downloaded HWMonitor to check temps, all were fine. My computer is older, so maybe that is the problem, but this problem seemed to happen overnight. My computer is AMD Sempron Processor 3100, using Windows XP. Any suggestions. By the way, this is first time I have ever posted online and I am not very computer savvy. Please don't be technical in answers, as I confuse easily! Thanks!

Download and run Process Explorer:

Right click on "services.exe" in Process Explorer, then click Properties, then the Threads tab, then sort the display by clicking the CPU column name (might need to click a couple of times to get highest CPU usage at the top). That should help you find what is running within services.exe that is using all the CPU.

I was also so confused because of system idle process but basically its higher value is in our benefit.
i launched a scan process and i see that system idle process value becomes 05 which is a very lower value.
when the scan process ends then system idle process value become 96 that shows the available cpu for other processes to run.
please note the picture....
