I have 5 Phenom 9600B (thats the business edition with a B not the BE - its supposedly more stable than the BE) desktops running at the office. I lost two over teh weekend. Werent doing a whole lot - just left on as usual and doing backups. These were stock non overclocked machines under a lease.
Specs - HP Compaq dc5850 Small Form Factor PC :

Do HP motherboards have a problem with Phenom Bs ??? its a 780V chipset and these machines are less than 6 months old. Temps are stable and in the low 50s. The machines turn on fine with fans but blank screens and no POST. Swapping the processor from one of the non dead machines allows the dead one to boot up fine.
Ironically my overclocked phenom desktop at home is still running great.

Core i7 920, 3GB Corsair DDR3 RAM, Gigabyte EX58-UD5, 1KW Antec, HD4850 ICEQ4 Stock Air 12999 3DMark06

possibly, it's the voltage setting. since your one at home is oc'd, you've changed (and thus checked) the voltage. since you didn't oc the work ones, they were left at stock settings. on asus boards, there appears to be a bios bug where the stock setting gets multiplied results in an actual voltage that is much higher. for example, my chip was set at 1.25, which is what it is supposed to be, but the actual voltage was 1.33v stock.

temps sound very high actually. try reading this article:
