Thank you George, That is a nice guide and very clear pictures. Most likely this is happening because of a loose part. I thought is was a virus, so I took out the hard drive and connect it to my desktop, but it runs perfect and no virus found. If onboard memory is bad, the entire system board must be replaced. But only till I reboot. My laptop never stays in the dusty environment. Thanks, the memory was in wrong.
