Hi, I haven't visited here for a while, but I thought I would post here as this forum has proven helpful in the past My problem is that red lines are appearing across my screen, and I'm assuming that it is my gpu. These red lines appear rather randomly but also more whilst gaming and on windows boot up screens. I have tried all of the obvious things; reconnecting all wires, have roll backed drivers to WHQL and re-seated card and components but lines still appear across screen at times. I've also done a RAM test which came back fine. So I was wondering if anyone could shed any light upon this for me, it would be greatly appreciated. Thanks.
