Screen display goes PINK

Check your monitor cable first! Try reconnecting your display cable both at the computer and monitor ends. If it's still pink, try reinstalling the vga graphics driver from the Dell Utility CD-ROM (Or download from Dell's support site http://www.dell.com/support/home/us/en/19/product-support/product/dimension-3100/drivers then select you PC model's video driver and re-install it. if after re-installing the video driver your display's still pink, try connecting to a different monitor - if a different monitor displays correctly, then its your monitor that's faulty. If it's pink on a different monitor too, then it's your PC video hardware that's got the problem - At least you'll know whether it's the monitor that's faulty or whether it's your computer's graphics hardware. (if your computer's video chip is faulty, then I suspect you'll need a replacement motherboard - $$$ - as I think the video is "on-chip" on the Dimension 3100 - so it may be time to consign it to the scrapheap and buy a new system if you can afford to)

1. Plug in an external monitor to your laptop. If the picture on the external monitor is good, then the problem is your laptop screen. If the external monitor also displays a pink screen, the problem is in your laptop hardware or software.

2 Contact Dell if your computer is still under warranty when the problem is with your screen. If your laptop is not covered by warranty, contact a computer repair shop to have the screen repaired or replaced.

3 Update your drivers and bios. Outdated drivers or bios have been known to cause screen issues. Visit Dell's Drivers and Downloads website where you can enter your service tag and find the appropriate updates for your computer.

4 Contact Dell's technical support team if the above steps do not fix the pink screen. Dell has had known issues with the pink screen being caused by the graphics card on some of their laptops. In many cases, replacing the motherboard is necessary to remedy the problem.

Is it Intel or AMD? Do you have the correct graphic card driver installed?
Go here, http://www8.hp.com/us/en/drivers.html locate your product and download the right driver..

While in Safe Mode....
Go to HP.com, Support, Drivers....
Download the latest video drivers, including the "Chipset" drivers.
Then, uninstall all video drivers by going to control panel, (System, Device Manager)
Reboot system, hopefully Windows will install the correct drivers upon reboot.
After reboot, re-run the new drivers

hi there.

you may use the given phone number below to contact the acer support if yoru screen shows the pink colors on BIOS so they can arrange a repair or screen replacment 800-816-2237

I've seen the screen go pink when the video input is set to the wrong type (composite instead of RGB). Try each input type to see if it goes away.

The problem is CCFL light bulb in the screen. It is starting to die :( Can be replaced but that is not an easy task (easier is to replace screen as new bulb comes with it)

First, plug a external monitor and toggle the screen to discard configuration or software problems. If the image displays correctly you have a problem either in the LCD screen or its connection cable.
Open the bezel and check for loose or damaged connection cable. Look specially next to the hinge, ON THE LEFT.
In case the problem is not the cable you might have to get a new LCD. You can have replacement parts and instructions here:

have you tried the video settings by right-clicking the desktop then properties>settings tab then either manually change colour support or go advanced. If it doesn't budge, try turning off the system, go to safe mode if it still has a problem, try reinstalling your graphics or video drivers.

Did you do anything in particular before this happened?

If youve tried pressing the degaus button on the monitor and the same result then either your graphics driver is corrupt and needs to be updated from the manufacturer web site or the monitor is on it's way out. Try a friends monitor on your system or your monitor on a friends, if it's the same on a friends ststem, it's a belated Xmas present for yourself.
