Rather than issuing blanket statements like "never work correctly" (which is not the case), it would help us help you better if you were to provide full details of your system. There are no known issues of general nature, the FF driver and mixer (with the FF800) work just fine. Also, if you are using Win7, then your comment about "every time windows (or for that matter, MS) comes out with a new operating system" seems a little out of place. The FF and mixer also work well with Win 8.
Which "three drivers" exactly are you referring to? And what does "tried everything" refer to?
How is the FF connected to the PC? If by any chance you are using a PCIe FW card, have you made sure to disable PCIe power saving in BIOS and Windows? If the FW is onboard, please provide details. Or do try a PCI/e card. Also try changing the Firewire driver to "Legacy" via Device Manager
