Moniter background is pink instead of white.
If the background is the only thing that is pink, then this will be as simple as changing your background color. the process is different depending on the operating system you are using, but if you right click on an empty space in your desktop chose either properties, or personalize. then choosing desktop.
If however this is not just affecting your background, meaning everything has a pink hue to it then it is most likely a hardware problem. To test this you can change to a different monitor, if the pink hue is gone then it is most definitely the monitor. However if the problem is the same on both monitors, then that would mean that your graphics card has gone bad. Many Pc's bought from dell, or hp have both video cards, and on board video. If this is the case with your Pc, you can move the monitor cable from where it is connected now, to the identical connection on the back of the computer. If you do switch to an on board video, please turn off your computer before plugging it in. This way when your computer is turned back on it will recognize that you are using a different video source. Most computers will do this automatically, however if it does not you will need to go into the "bios(cmos)" and enable onboard video. The option for bios is given as the computer first starts up. The key varies but it will be one of the following f1,f2,f10, or delete.
