Hello. My name is***** will assist you with your question.
This is a common problem with some systems under certain versions of the operating system. Unfortunately I don't know which of either of those you have. Can you please let me know the model of your computer and also the version of your operating system?
The short answer for this, if it's acceptable to you, is to change the power settings so that the system never hibernates. Hibernation seems to be the one state that causes the largest number of problems. Of course, disabling it completely may not be an acceptable option. But, it would be a good way to troubleshoot the problem. Finding out if one mode at least is causing the problem. Let me know you can I'll continue to help you until we've either tried everything we can or until it's resolved.
