It's a GTX 780 that's been in there two years and never given me any trouble (except for when it misjudges where my screen starts and ends, which is fixed by reboot/unplug HDMI and eventually disappeared completely), never overheated etc. This issue appeared round about Windows 10 1511, where there's a green line flash across my screen (usually coming out of a game). It's minor and only there for a second at best, but it didn't happen at all before

Pertaining to driver issues you should almost always uninstall your drivers and reinstall them as Windows 10 by default has the option to automatically download device driver updates. Disable it following this guide. Next thing to do is follow this guide and reinstall your GPU drivers.

In the meantime you should make sure your BIOS is up to date alongside your chipset drivers.
