XP Xperts,

I have an HP Pavilion ze4100 laptop running Windows XP with 640 MB
memory, and plenty of disk space. When the machine comes up, the CPU
arbitrarily jumps up to 100% usage, and the mouse pointer disappears.
After some time, the CPU usage comes down, and back again to 100%. This

continues, making the machine un-usable.


I have checked the machine thoroughly for viruses, found none. It
had thoroughly been cleaned for Adware or Spyware, with several
different programs, and is clean. I re-installed Windows XP SP2 without

any problems - after re-formatting the hard drive. The problem still
persists.


The crazy thing is, task manager reports the top most window's
process to be consuming 100% of the CPU. That is, if I have windows
explorer as the window with focus, task manager will report it having
100% of the CPU, if IE is the top most window, it will have 100% of the

CPU. If no windows are open, just the task manager, the task manager
process has 100% of the CPU.


I have looked all over, but have no clues. Any and all help
appreciated at this time.


Best,


Raj.
