I thought that creating another user may offer some clues. It seemed to help when running adaware, ewido, spybot and avast. They found the trojan virus, conhook_l and another, coulomb dialer. Then I used HijackThis to take out a couple of lines with these names in the records. I think they are gone. Once or twice while running Spybot caused the crash.
I am trying to determine if there is a heat problem or a virus. I propped up the laptop with a fan blowing on it to see if this changes anything.
I also ran Ghost and Windows Backup. Both ran to completion in the second user account.
