Hello mklc, it could be your power settings. Here's something to try.

Start menu> Type in Power Options> Click on Power Options in results above

Whichever option you have checked now (I use performance), to the right click on Change Plan Settings

Click on Change Advanced Power Settings> Expand the PCI Express> Link State Power Management> Set to Off> Apply and/or ok your way out

See if that helps
