To help us assist you, please provide more information:
1) Decribe the issue you are having in detail. For example if its with a specific piece of equipment, include the make and model.
2) When was it last working normally? Since then, did you add/remove any software or hardware?
3) What steps have you already tried to resolve the problem? (rebooted, searched google, etc)
After trying different solutions provided by google, I found one that worked. I cannot tell which one but when I turned on the computer the next time it no longer comes up on the screen. I went through about four or five ideas from the google search. Thanks for your concern. Denny at Thunder Lake Realty
