Quite often (at least several times an hour) my system tray/tool bar becomes inaccessible and applications freeze. When I press CTRL-ALT-DEL and look at the processor usage, it is showing 100% and then goes to zero just as soon as I start looking at it. It "appears" to me that something malicious is hogging the CPU but nothing shows up in the process ID listing. It's almost as if the code is sensing that I have pressed CTRL-ALT-DEL and it immediately hides itself. Is there any utility or any way possible for me to capture what is happening prior to and during these lockups? I am about to reformat the entire thing and start over but for future reference, I would love to have access to a utility that would allow me to have a complete log of all events and perhaps how much of the CPU they are utilizing without having to press CTRL-ALT-DEL. Your thoughts would be greatly appreciated.
