The biggest problem I'm having with my SP4 is that the screen sometimes flickers. It doesn't turn off, it just varies is brightness very quickly. It also holds on to an after image, usually when gaming, making it difficult to see what's actually happening on screen. If I take screenshots with Steam, they are saved normally, without the weird watermark image from the previous screen. At one time I didn't shut off Steam right away, as I couldn't save at the time, and when I finally did, the afterimage took a long time to clear out, even after restarting. Though it usually happens with gaming, it has also happened to a lesser degree when running art programs. The specs are 16GB ram and intel i7. The only reason why I got the strong (and consequently expensive) specs was so I could use for gaming, since the minimum specs would have been enough for art and web-design alone. Right now even getting off Steam and the watermark fading, the screen still flickers. I have it out of its cover and have a fan pointed at it, as it sometimes feels warm, but cooling it off isn't getting rid of the flickering. In the past I used to hear its inner fan but I haven't heard it much lately. I don't know if it's true but I heard that supposedly Microsoft updated it because people where complaining about the loud fan and there's been cases of it overheating all over the Internet. I didn't mind the fan's noise. If it is a buggy update, how do I get rid of it? I had high hopes for being able to do web-design, art and gaming all in one machine, but the SP4 has been a terrible disappointment so far. At this point I'm just trying to salvage what was admittedly a bad purchase I regret. Any ideas?
