I recently got a new computer that didnt have a firewire port on it so I had a Texas Instruments OHCI Compliant IEEE 1394 Host Controller put in it. I plugged my PreSonus Firestudio into it and ranCubase LE 4. It worked perfectly fine until my computer randomly restarted. When it was done restarting a window popped up and said that it encontered an ups problem.It usually goes for about 30-45 min before it restarts. Everything else on my computer exceeds or meets the requirments for my interface. Please Help.
