I have a Steiger Dynamics PC with a 780 card. After I installed Windows 10 Creators Update My screen had green lines running through it. I rolled back the update and everything seemed fine. Sometime later, after another update I had this happen again which I disabled the card than reinstalled the drivers for that card. On Saturday 9/23/17 I got the lines again and I lost sound on the PC. Never have I lost sound before. Could all of this relate to a failed graphics card? It has me wondering since I purchased this rig in 2013 if it is even worth repairing it.
