my problem happens when i' closing the screen and the notebook enter to sleep mode, after opening the screen again it's wake up but with color problems, can't see nothing and it's all in green crap color...
what can it be? any ideas how to solve it?
I've never heard of that before.
Reinstall your video drivers. If that doesn't work, reinstall Windows. It is definitely not a hardware issue, so it is probably something with the OS.
^Agreed. What operating system are you running?
Also, I have a feeling that the issue may be happening because of SLI, because to be honest, that's the only reason I've seen similar problems occur.
