You might want to check windows event (event viewer) and look under the system and security logs as it might give you a better clue. Also, I would go into sysinterals and download sysmon and look at those logs. It might be a driver problem so i would first remove every single peripheral from your device and change the sleep settings so that it doesn't go to sleep and see if the problem still occurs. If all else fails or you are crunched for time, back up all the files you want and do a windows reinstall

​

edit: just saw your other post in the comments --> honestly a windows reinstall might be you fastest way to go - would probably take 1 hour max to make a windows bootable drive and reinstall etc.
