Why does my Pc monitor sometimes darkens and then has grey horizontal bars or lines going up and down?

This is very recent and the cause is unknown :S


Symptoms: Monitor will be very dark and you can see lots of grey horizontal 1cm think lines running up/down the page really fast. During random times, it'll turn back to normal but then it will happen again.


I've check the connections and both ends seem to be really in without any loose ends.


Any ideas?|||It's going to be one of two things, either the monitor or your video card.





Try the monitor on another computer and see if it does it. If it does the same then it's the monitor. If it doesn't then the problem is looking at your video card.





Or do it the other way around, borrow a working monitor and if it does the same then it confirms the card.





Process of simple elimination really.|||anything with large magnets in near your screen. big speakers or something.


my laptop screen now (after having it for a year and nothing happening) occasionally gets purple lines flickering on it and i'm pretty sure this is from magnets or a problem with the wires connecting the screen|||your monitor life is about to end. the only solution to this is changing monitor.





If you are still in doubt , plugin your monitor with another system and if same lines appear then it is certain that you need to change the monitor. .|||I'm afraid your monitor has come to the end of its life. It will close down on you altogether soon.
