Help!



I just got a new mac pro. When installing my additional hard drives (1 WD 300gb, one 300gb Seagate) into bays 2 and 3, the computer does not start. The GPU and CPU fans just go crazy and the monitor is blank, backlight doesn't even turn on.



I was able to get the computer to start after installing the WD drive into bay 2, but the drive does not show up on the computer. I only see the standard drive shipped by Apple.



Can anyone help me get my 2 other drives working?



Thanks.

    Pull the drives, make sure they are SATA II, there are NO jumpers on the pin block, put the drives back in, & hold CMD Option P R at the same time at startup.
