I am attempting to determine what is causing my notebook to keep shutting down at random times. I don't believe it is overheating as I have an extra fan for the notebook to sit on and it does not feel too hot when it does shut down. Any tips to help find the cause to get this corrected? I would be glad to provide any needed details to get to the root of the problem. I don't believe this is a Vista issue - believe it is hardware of some kind. Thanks in advance for your assistance.
