computer screen's color

[tasos123]

Hi, my computer screen's color changed suddenly to a purple one. I uploaded some screenshots that may help you. Could you please give me some suggestions to solve it? Thank you in advance!

Wiggle your video cable. It's probably a failing cable.

I done it but nothing happened...

Change cable, try different monitor, try different video card. If you reboot is it still purple? What about booting to safe mode?

I get this if the VGA connection isn't solid. Do as suggested above, do you have any other video outputs like DVI or HDMI?

Thabk you all, especially @voyagerfan99
It was just the cable fault. I wiggled it and now it works fine!
