Windows XP (and also Windows 7) does not allow the installation of hardware components that are not certified with the logo or not pass the test digital signature. In short if the previous operating system on all our hardware worked perfectly, after upgrading to XP may be that some are not enabled. The problem is obviously the driver, or software that interposed between the hardware and operating system. In our case it happened to a TV card under Windows 98 gave no problem.
Well there is a solution that can be attempted with this type of problems involving the activation of the Registry Editor in Windows XP.
Open the Start Menu, Run and enter. Type regedit and enter to enable the Registry Editor. Date sent consecutively to headings: HKEY-LOCAL-MACHINE, SOFTWARE, Microsoft, Windows NT, CurrentVersion.
At this point the right hand side that contains the string ProductName the value Microsoft Windows XP.
Take note of what changed, why, after installing the drivers, you must replace the initial value you are editing. Replace the string with the name of the operating system that supports that type of hardware, such as Microsoft Windows 2000. Do not reboot your PC, install the driver that gave us problems and that is the case here are those of Windows 2000.
Finally properly reset the registry key that we had changed the configuration and reboot the system.
