A friend reflects that Windows 7 released the RC version can not correctly identify the video card below GeForce 6, the display effect of natural discount. While installing Windows XP system driver can correctly identify the video card, but after the installation of the computer is often blue screen, also can not play most of the video files (only RealPlayer can successfully play AVI and RMVB files). In addition, the screen saver cannot run except for blanks and slides, as long as the selection results in a blue screen.
I suspect that the problem is in the video card, is likely to be the driver of the problem. To verify this, I downloaded a variety of n from the Internet from the official and unofficial drivers of the Vidida graphics card and tested it (the video card I used was GeForce4 MX 4000). In order to maximize the performance of the graphics card, the author from the latest driver to start testing, until the 91.98 version of the driver, the blue screen problem has not appeared again. But here's a caveat, because the driver installer does not correctly identify the Windows 7 system, so install the driver either manually or with compatibility mode.
Next, I talk about some problems found in the trial drive. One is that Windows Media Center (WMC) program does not start. The author found in the test to start WMC, the graphics card must have more than 64MB of memory, otherwise the system will be prompted "TV and video may not work properly, because the video card does not meet the RAM 64MB minimum memory Requirements" (figure). The second is aero special effects. Depending on the results of multiple tests under different drivers, the early graphics card can be forced to open the aero effects, but not the normal display, up to only mouse movement, all content on the desktop can not be displayed, but the non-aero theme can be used normally.
Because Windows 7 is currently not officially listed, there may be such or such a bug, like a taste of the users do not want it too high. I believe that with the continuous improvement of the system, as well as hardware manufacturers in the drive improvements, many problems will gradually be resolved. Of course, for users using the old platform, if you have a hardware problem with the new system, try some "old" drivers, maybe Vista.
