I had an areca arc 1300-4i an a hp expander working perfwctly in windows 7 until I reinstalled the OS. Afterwards when ever I try to install the driver the system freezes and on restart it hangs on the "starting windows" screen. I updated to the latest areca bios and the problem remains. The expander shows up in bios and I did a test install in linux opensuse and the two worked together perfectly so it seems like a windows issue. Any help would be great!
