Hi wolfmountain1, The first thing to try would be to disconnect all external devices except the monitor. If that doesn’t work try the power supplies one at a time. Next would be to disconnect the backplane so the hard drives are not connected. If that doesn’t resolve it try to remove any PCIe cards and see if that works. The step after that is to go to one memory stick per processor.
My PowerEdge T610 has stopped booting this morning. It now runs in a continual cycle of trying to boot for about 1-3 seconds then it appears to crash. After being off for a few seconds it trys to boot again and crashes again after a couple seconds.  Basically all the lights on the front flash on and the LCD screen says "System Booting..." and then it all crashes within the first couple seconds of the fan revving up. I get nothing on my monitor screen to even show me it is trying to start into BIOS.  Any ideas or directions you could point me in would be much appreciated.
