After updating to the WW Bios, my system failed to boot up or the power comes on for several seconds and then automatically shuts down with a couple of 'beeps'. Why?

WW bios has a brand new CPU protecting function. If the CPU fan reading of fan1 header lower than 2000 rpm, or the fan is connected to header2/3/4 or directly to power supply unit, this BIOS will automatically SHUTDOWN THE POWER IN 10 SECONDS. This design protects the processor from damage by heat. Thus if you are not sure the current CPU fan is correctly on fan1 header , DON'T UPDATE TO WW PLEASE! The fan1 header is closer to memory sockets while fan2 header is closer to CPU socket. Wrongfully update to WW may cause system never boot up again unless you connect a suitable CPU fan on fan1 header. However, even the system meets fan1 requirement, take the following steps after bios update please. Pull off the power cord or switch off the poser supply unit. Reset the CMOS data by moving the jumper from 1-2 to 2-3 for several seconds then put it back to normal position 1-2.
