Maybe strange idea, but have you checked, that the device in QuartusII matches the target device on the board? (in case it's an iteration of an existing design it should).

I had similiar stuff with prototype units I'm working with after several reprogramming and USB-Blaster connect/disconnect cycles. Unfortunately all devices showing the issue you describe were physically damaged, most likely by voltage peaks by connecting / disconnecting the USB-Blaster...

Hope your's problem has other than physical (broken device) reason...

BTW: I do not think it's an installation issue - maybe you can check the JTAG I/F in QuartusII (try to have Quartus find any connected devices).
