From: Jay on
It is not every night. I have already disabled temporarily different
scheduled tasks that are set up to be performed at night (SBS backup,
updates, etc).

I have made sure that the PSU and UPS work OK.

I have replaced SATA cables that connect hard drives with RAID controller
and the system was working without freezing for 12 days (I was receiving
messages about Delayed Write Failures when this RAID was being backed up).

I was wondering if anyone could let me know the right steps that would help
me to solve this problem.

Many thanks,
