Hi Andrea.Nenci,
I am sorry you are having this problem but let me help you.
It is important to say that the HM55 chipset is a legacy product at this point and the support for this got up to Windows 7. If you have an Intel® motherboard with this chipset, you can check the Operating System compatibility chart at this link:

If you have another branded computer with this chipset, it may be necessary to install the chipset driver provided by the Computer Manufacture.
You can try our .INF but it is a generic driver and there is a chance it may not work properly. Here you can download it:
