Blue tinted screen

[user24]

Hey I'm having an issue with my screen, it has a blue tint. It just happened while the computer was unattended. No one has adjusted any setting. Please help.

Edit: Also, anything that appeared red now appears black.

I'm assuming you're tried rebooting? If that didn't fix it, you could try reinstalling your graphics drivers.

Download the latest drivers for your card, and then use this utility:
Driver Cleaner Professional download from Guru3D.com
(Make sure you follow the ReadMe file!)

make sure the cable is plugged in all the way in the back.

Maybe you could try the "degaussing" feature.
