XPS L502X display issue

Hi,

I'm having a display problem with my laptop XPS L502X Windows 7 x64. I tried to install an old version of the video driver (Intel HD Graphics 3000) but it didn't work. Then I formated the computer and installed manually the drivers and I'm still getting this display problem:

Suddenly the screen turns purple, blue, black, grey and in most of the cases it turns off for a few seconds. Then it turns on with a different resolution and I got this message:

Does anyone know how to fix this?

Thank you,

Evergaan
