Was hoping to get msinfo32 with your zipped file.
A driver is causing an inconsistent power state.
Don't have list of drivers, so you will need to check the latest drivers for video, network and Realtek audio.
Also, try running msinfo, going to startup tab, and unchecking all drivers EXCEPT those belonging to Microsoft for testing purposes.
Has this problem always occurred or is it recent? If recent, was it after an event, such as program install, power failure, etc.?
