    IN recent weeks I have commenced experiencing what appears to be a "hogging" of my resources. It first manifested itself during typing of simple email messages. One or 2 lines of type on the monitor screen would follow in sync with the keyboard and then, suddenly, the cursor would stop even though I continued to type. Sometimes it would approach as much as a minute before it would catch up to where I was on the keyboard. I also noted these interruptions in scrolling, in backspacing, etc. Today I was in Task Manager and noted that there were 51 processes listed and even though no programs were running the CPU usage indicator for one of the processes, "System Idle Process", was jumping back and forth between 00 and 100% (all the others were holding steady at 00 or thereabouts). I am networked (2 computers) with a router and builtin firewall. I'm also using Norton Anti-Virus and Zone Alarm Pro. Frequent scans for viruses show up nothing. I also frequently run Spybot & Destroy, Spy Sweeper, and Ad-Aware. So I don't believe it's a result of hacking. What else could it be? Can someone tell me what the "System Idle Process" represents and what kind of readings should it be showing when nothing is running? I have a fairly fast processor (1.5 Gb), 256 MB Ram, and am running XP Pro.

    System idle is supposed to be at 100 when nothing is running.

    Do this, in the process tab click the CPU column twice and that will sort the processes in orer of highest usage. SYstem idle will normally be at the top, what else is there.

    Oh, and break up your message, it is hard to read with no line breaks.

    System idle ranged between 90 and 99; Taskmgr.exe was next fluctuating from

    00 to 38; Big Fix.exe occasionally got into the action fluctuating from 2 to 8, or

    so; and for the most part all the rest stayed at 00. Oh yes, there were a

    couple of jumps to 2 or 3 by one or 2 others but that was about it.
