I;m having a problem with my PC. Hope someone can help.

Cursor moves spasmodically across the screen. Jerkily, that is. I have
cursor  controls set to the highest speed now, No difference.

Audio files played on the computer often stall, stop and repeat, as well
as the audio in video files, all when played on the computer.

Captured videos are also  choppy, and the audio is choppy. when played
on both the computer and my Phillips  DVD/CD player

I note that something on my computer is drawing up to 100% on the CPU at
times even when the machine is at idle. This totally mystifies me. Any
ideas?? Obviously something is running and I can't find what.

Thank,

Regards,
