I have been using dell Vostro 2420 laptop for the last 2 years. I had windows 8.1 installed in it in the last month. When I was using windows 7 I got occasional display problem with display getting blurred(consisting of close horizontal lines, and picture getting shifted to left side of the screen). According to the instruction from dell, I uninstalled both intel and nvidea display drivers. They got reinstalled automatically after restart. Now I got the display error again. I uninstalled the display drivers. But only nvidea is automatically reinstalled. When I tried to install intel hd graphics driver manually, it shows that "the computer does not meet the minimum requirements for the installation to complete". What to do? Please help.
