Hello,

I have this problem for already about a month.

I have Asus N55SF laptop for around 2 years now. For almost all of those two years I am (almost every time) using external monitor. Would it be for watching movies, tv-series, games or working on dual monitors.

Recently I've been having this problem with my display. It starts glitching, by that it goes black and two lines appear in the left side of the monitor.

If I'd have to guess I'd say it's the graphics of the laptop. But how do I check that? Can I use some kind of software maybe to diagnose the temperature of the laptop and so on?

Em, I forgot to mention about my battery. Not sure if its important, but it's been 'dead' for quite a while. I mean without charging it lasts maximum 20 minutes so my laptop has to be constantly plugged in.

Well I will try that. The thing is that I havent seen that while gaming (though I havent been playing games so much lately, so don't know), but I wouldnt suspect overheating as main issue.

My theory was that it got overheated in some time before while I was playing games and maybe TV on external monitor and now its giving me this glitch, because they appear seemed to be out of nowhere when I am working on entertainment mode or doing just about as little as browsing web.

I've updated both drivers after a problem occur, but it didn't seemed to change anything.

The thing is that on even when I plug my external monitor in it does that thing, but only on my laptops monitor. So that again gave me suggestions that something between the graphic card and a display of the laptop has malfunctioned. Only when it shows the message of that "Windows graphic driver accelerator had problem occur and shutdown" it turns off my both screens and restores in few seconds again.

Well after browsing a little bit more about this problem, I found the post which recommends removing some Malware, guess what - it helped. Didn't really expect virus to make these kind of a glitches, but some Malware is using all the GPU. Installed Malwarebites Anti-Malware as recommended and it helped. Though I still see numerious connection attempts blocked through uTorrent.

Malware shouldn't be causing those display problems. What you're probably thinking of is a bitcoin mining virus where someone is using your gpu to hash for his miner. You should still look at temperatures, I don't think I saw you post them yet.
