Computer started flashing colors? - Maria - 04-28-2013 11:35 AM
I pluged in my computer and it started showing colors, kindof like when a tv is on with no signal, but more colorful. I started pressing stuff like ctrl+alt+delete and the off button. After about 20 seconds it stoped and when I turned my computer on again it started normaly, but with the "do you want to run your computer in safe mode" option. All I know is that I pluged my computer in. My brother and sister were by the computer at the time, but they said they didn't do anything and I belive them.
My computer is a dell laptop
runs on windows 7
I got it in August.
WHAT HAPPEND AND WILL IT HAPPEN AGAIN?

they did something wrong and ask them what they did in the computer.
. Your screen reselution may be wrong. Change it to it native settings.
2. Your monitor's refresh rate is noticeable. Change the refresh rate to a low number hat you are comfortable with (WARNING!: a refresh rate below 75Hz can cause eyestrain).
If those dont work than contact tech support.

Hello Maria,
My name is Krishna and I work for the Social Media and Community Team at Dell. Based on the above symptoms, It's more likely that you have a bad video card or corrupted video drivers.
Try running the hardware diagnostics and see if it shows any errors. You can follow the instructions from http://dell.to/dU0fpw
If the tests come out clean, then you can perform the troubleshooting steps mentioned in the link below and see if it helps.

Hook it up to an external monitor and see if it happens again - it might be the laptop screen, it might be the graphics card, or it might be a momentary glitch.
If it shows up on the external monitor - it could be the graphics card. If it doesn't, then it could be the laptop's screen. If it doesn't show up again for months...it could be a momentary glitch or you could try updating the driver, in case that got corrupted.
