Hi all:

I've been having a problem with my Matsu****a CW-7503 burner (it's an OEM of panasonic). After my computer is on for a few hours, the burner will power off. It will not open. It can't be accessed. I have to power downthe system and it comes back on.

It is SCSI, but I think I have all the setup done correctly. At times it will completely lock up my system when it shuts off.

I've changed PSUs (300 and 350 watts), cables, and SCSI cards and i get the same problems.

Any help anyone can give would be great...
