DC, Server 2003, Exchange 2003, BackupExec, Sophos, Nothing newly installed... maybe MS updates a couple weeks ago. Certain NO Malware NO virues.  These shutdowns started Thu 3/08 out of the blue and continues. The last one was today around 2:03 PM. Dell has a GUI Online Diagnostics that DOES NOT check power supply. Pretty much the results are OK. No event logs except "unexpected shutdown" and the routine startups that follow 15 minutes later.

I guess my question:

Does anyone think this is more than a power suppy issue... and is there a way to know for certain?

Frequently when I've seen something like this, it's bad memory...
BUT
Do you have this box connected to an UPS?   If so, try plugging straight into wall outlet
Just had this at one customer, plug into wall..no more shut downs

In order:
1) CPU Overheating (should have been checked by diags; but SIW would show you temps under sensors: http://majorgeeks.com/SIW_System_Info_d4387.html )
2) UPS (?) failing (try bypassing straight to wall or another UPS)
3) Power Supply ($69.00: http://www.ebay.com/itm/Dell-MK463-Power-Supply-750-Watt-Precision-690-SC1430-/350541997508?_trksid=p3284.m263&_trkparms=algo%3DSIC%26its%3DI%26itu%3DUCI%252BIA%252BUA%252BFICS%252BUFI%26otn%3D21%26pmod%3D200721948564%26ps%3D54 )

Enable dumping. It can be BSODing. Right click on My Computer - Properties - Advanced system settings - There System Startup, debugging etc. Press on Settings - Small Memory dump.

After 40 mysterious restarts in a 72-hour period the system finally "Halted on COM1". Looking closely at the controller card, we noticed that the capacitors were swelled. We replaced the controller card and voila!

Thanks everyone for your suggestions. –M
