After a power-outage, there's RED Lamp inside My Mac Pro. I do a Diagnosis (by inserting the DVD Installer that came with My Mac Pro, and pressing "D" at the startup chime) And I got this problem/trouble: Code: 4SNS/1/40000001:VMBS Anyone know what problem is that?? But Thanks God when I totally unplug My Mac Pro few mins, and then plug it back, all RED Lamp inside My Mac Pro were gone!! And when I do a Diagnosis again, there is no problem/trouble found. Has anyone encountered the same problem with mine?? Any reply would greatly appreciated. Thank you.
