I bought MSI CR420. It came with DOS. I installed win7 ultimate in it. Then installed the graphics driver (intel GMA HD) and after that it started showing some lines on my lapy's screen. I thought it maybe a hardware probelm but when I uninstalled the graphic driver it started working properly in 1024*768 mode. The laptop's specifications says that it can support 1366*768 but it is showing lines on screen and it flicks. I also tried windows xp and again after installing the graphic driver the same problem occured. How to solve this issue?
UPDATE : Folks, there was problem with the hardware. The extra RAM of 2GB which I attached to it was not working. I put a new RAM and it worked. Thanks.
