I have this weird issue with my laptop in which after I wake it up from turning off the screen for around 10-15 mins, some kind of messed up columns of coloured thing in stripes appear. This clears out after I refresh the screen or drag a window across it. I'm worried because the laptop has only been around for a year old and it's already doing this. I've downloaded the latest drivers and installed it but it still does it.
Attached are some few shots I have since I've done trying an SS but those weird stripes didn't appear in those SS's.
Any help or suggestions would be gladly appreciated! Thanks you!
