Some days ago I installed Windows 7 on my old laptop. Before that, it used Windows Vista. It used AMD Turion X2 processor and ATI Radeon X1200 as the graphic card. Black screen occurred mostly once a day. After it happened for two days, I checked for solution on the internet but most of them isn't resolved the problem clearly. After read some articles and discussions in some forums I got some information. There are two types of black screen problem. First is black screen after booting. Second is sudden black screen when we run Windows 7.The problem is not only because of Windows 7 but also the graphic card driver problem. As I know from AMD, they don't provide the best compatible driver for ATI Radeon X1200 to run in Windows 7, only for Windows Vista. In this writing, I will explain how I solved black screen problem on my laptop. My black screen problem is not the first kind but the second.
