I have a MSI Wind U100 Netbook from a small number of months. I essentially make use of this for internet access just for my study intention and with that like to play some of the HD games. The machine was running with the windows XP platform, at the present I installed windows 7 for enhanced gaming. But in this the major problem is after installing the windows 7, for the first few days the machine create a few difficulty while attempt to start window, but from yesterday it stopped functioning in normal mode. And also I am unable to start the machine in windows normal mode also unable to play game. What should I do? Any hint on this will be appreciated greatly.
