Hi,

How about your problem now?

According to your description, this should be hardware device driver problem.

You can follow the method below to resolve it for test.

Firstly, check Motherboard and BIOS edition to make sure both of them were upgrade to be latest.

Secondly, reinstall Graphic Card driver to make sure it was upgrade to be latest.

Hi 

I have heard some users mention this very issue. While the solutions differ per machine, one that stands out is to uncheck the "Allow this device to wake the computer" option of the network adapter properties in Device Manager. 

Secondly, you can also consider using the Power Troubleshooter. Control Panel -> All Control Panel Items -> Troubleshooting -> All Categories. From there you can start the Power Troubleshooter and start the automatic detection to find possible issues.

Lastly, you could check the power settings of your PC. While I doubt this could be the issue, it is worth checking out. Edit the plan settings and click on 'Change advanced power settings'. Have a look at the 'Sleep' and 'Multimedia settings' and scratch around there.

I hope you are able to solve your issue soon. Good luck!
