When I installed Windows 7 64-bit on my machine with the motherboard X7DBE, the Device Manager told me that under “OTHER DEVICES” there is a “BASE SYSTEM DEVICE” with no driver. I do not know what this device is or how to update its driver. I have installed the chipset drivers from your website; however, no set of drivers specific to Windows 7 exists on your site, so I selected the download for Windows Vista. Could you please advise me?
