Thank you for contacting the Intel community.
After reviewing this motherboard information and compatible operating system, I find out that this motherboard does not support Windows® 7, this is an old motherboard and at that time it was made to work with Windows® XP and other operating systems before Windows® Xp.
At this point, the only option is to try to update Windows and check if that helps if not you will need to go back to Windows® XP.
I’m sorry this is not what you wanted to hear but this is the reality with motherboard and since you have Windows® 7 installed now there is no driver available to solve this issue.
