Hello, when Windows 8 came out I updated my GT680 to Windows 8. Most part works fine, but the USB section made problems. Sometimes the USB port are not working. Disabling and reenabling them in device Manager solved the Problem, but USB 3 ports with USB 3 devices are not usable. The baddest part was boot behaviour. Fast boot works mostly fine, but after a complete reboot system won't start. It took some recovery attempts before it works again. I thought it is a driver problem and lived with it for some time waiting for updates. Last week I saw msi removed Win8 - Drivers from their website. I called msi Support and they told me that Windows 8 will not work on GT680. There is a bios update necessary but msi would not provide one. I saw in this Forum that there a some custom bios versions. Will they help to solve this Problem. My only interest is to run Windows 8, I' m not interessted in overclocking etc. best regards Stephan
