Werid colours on the monitor

This morning I booted up my computer as usual and everything went normal. So I after about and hour I went to upstairs and then came back down and I noticed the whole screen was covered in purple, blue, and green tints. So I did the "Degauss." It eliminated most of the colour exepet for one annyoing green bloch up on the top of screen, and a black haze around it. It also curves the screen up. (I tried to paste a picture but when I did the screen looked normal)

Thanks for any help

 

Try checking the monitor-cable between the display adapter an the monitor (Disconnect / Connect)
Try attaching a different monitor (If the problem persist then it is probably an issue with the display adapter)

 

And make sure no Magnets are around your monitor.. Lol..

 

That includes large speakers/subwoofers/deathrays, ya know, things like that.


EDIT: This is actually something to do with the monitor itself (or it's cables/connections/etc.), not software. That's why when you try to "paste a picture of it" it will look normal, because the software is outputting the screen just fine, the monitor is not.
