I have several APC UPS 3000 RM units that have gone bad for me. The lastest and greatest one happened to me on monday when I powered it on. I heard arcing and sparking and then a loud Bang before it shut off and the smell of burnt electronics reached my nose. I opened it today to find Q7,Q8,Q9,Q10,Q11 and Q67 had all exploded, along with charring on the circuit card and a few of the resistors.

Is there a Design Flaw with the SU3000RM3U? I noticed another thread where this has happened.
What could cause this to happen?

Thanks for any and All Information.
