Hello about 2 days ago when i turn on my computer my desktop was in 640x480 resolution and only 16 color. I thought thats problem with my graphic card so i open device menager and saw that i have warning with my two graphic card. My Intel HD 3000 shows "code 12" and the second card (which is GeForce GT 540m) was shown as "standard graphic card VGA". I tried to install drivers but setup cant see my graphic card. Even when i pint driver file directly error come out and say that "selected driver for this hardware is not compatible with this windows version" besides that i downloaded right version of driver (win 7 64 bit). The most strange thing is that the AIDA64 program shows that i have geForce 420m instead of 540m. Ubuntu sais the same, but when i switch to linux i have normal full HD resolution. Thanks for any sugestion.
