Like the tittle says i have what i'm guessing is a memory like on my computer. I built the rig about three weeks ago and stared seeing the problem day 1. It does not seem to happen when i'm playing games from steam at all. However i have noted it while steam or Battle.net app are downloading games also noticed it when watch things like Netflix or Funamation in full screen. I have attached a picture of what i'm talking about.
Also i have changed the size of the paging file just encase
I'm using
Cpu:Intel Core I5-4690
Motherboard: ASRock Fatal1ty Z97X Killer ATX
Ram:G.Skill Ripjaw 8GB
Graphics card: Sapphire Radeon R9 290 4GB
Any thoughts on this would be great i'm just not sure what to do
Thanks
