bouncing cursor
I have a Dell XPS 15 Z laptop with 6 GB of RAM, 4 x 2.53 GHz processors and 500 GB hard drive which is only about half full. The operating system is Windows 7 Pro/ 64. All updates are current. I have Kaspersky anti-virus, malware bytes, & spybot search and destroy. All of which say the computer is clean.
Regularly my cursor starts jumping around the screen for two or three seconds. Even though the computer does not have a hard drive activity light, I think I can hear the hard drive going when this happens. If I wait a few seconds everything settles down and I have perfect cursor control from the touchpad. I've tried plugging in a mouse and I get the same effect, so I don't think it's the pad itself. The Cyprus touchpad drivers are up to date. I defraged the hard drive regularly. This happens in any program on the machine.
I have seldom seen more than half of the Ram used. The processor load is usually 15 to 25%. I can not detect any relationship between what programs or how many are loaded.
Since the computer seem to be needlessly swapping to the hard drive, I've tried increasing the virtual memory to very large values and decreasing it to a minimum. Makes no difference.
Thanks
