Since I downloaded the last microsoft security update, my computer will only run for an hour or so and then it shuts itself off without any warning and i can not start it again unless i unplug it first and then hit the power button. What is wrong and who do i fix this? Anyone else having this problem? Gene1 person needs an answerI do too

For home users, no-charge support is available by calling 1-866-PCSAFETY (and/or 1-866-234-6020 and/or 1-800-936-5700) in the United States and in Canada or by contacting your local Microsoft subsidiary. There is no-charge for support calls that are associated with security updates. When you call, clearly state that your problem is related to a Security Update and cite the update's KB number (e.g., KB977165). (Thanks to MVP PA Bear for this information.) If you are not in the United States or Canada, there are local support contact numbers here: http://support.microsoft.com/common/international.aspx MS-MVP - Elephant Boy Computers - Don't Panic!
