Left my notebook for a while and find it out in a sleep mode, after awaking - saw it with the multiple coloured (like white noise) and solid gray lines on the display.

I read a lot here, but couldn't find the solution. found out it could be some issue with the nvram. I followed the instructions from here http://support.apple.com/kb/HT1379 and resetting helped. Next morning - the same story. Screen looks like it is devided into lines - first the same multiple coloured and solid gray lines, after resetting became - black - white - black - white - and etc. and after resetting nvram again - it starts to look normal.


It is not old - something like one year.

Couldn't go to apple service center right now - because it is far away, in another part of the country.

Somebody know what is this problem? Is it graphics card? Or else?
