multi colored strip on left of screen in game.

[Archer 56]

New Build, z97 MSI Gaming m\b, asus gtx770 GPU, i5 4670k CPU , 750 W p\s, 8 GB Ram, corsair H60 water cooling. My problem is I'm getting a multi-coloured strip about 1.5 cm down the left side of the Gaming screen (not in Netflix,chrome or even normal windows; Only in games.) What is happening ? I have all latest drivers, nothing is overclocked. tried different monitors and Gpu's so it's not that nor is it overheating. Starting to feel suicidal. Any help Pls.

Problem sorted. Did a complete re-install of Windows. Must have been a software glitch.
