[QUOTE="thevaas, post: 1601571, member: 331901"] Hi Nick, In response to your earlier query, I removed the Video card and tried to boot. Same effect. No startup chime/Just fans spinning/White light is steady. I checked the Diag_LED and this time LED 2 and 7 (Power On) light up. The LED 8 (EFI) sometimes lights up green when I keep the DIAG_LED pressed for sometime. Other than that it's still the same. I also tried putting my old NVIDIA graphics card (It could boot on safe mode the last time I checked), but it shows the LED 6 (GPU) as off and again same effect. Could it be the PSU or the Logic board? The PDF document doesn't talk about this - just the precautions or troubleshooting by removing/adding cables etc. UPDATE #1: I kept the machine switched on (without the video card) for a good 10 minutes. Now the "EFI" LED 8 lights up green along with LED 1 ("Trickle"). The LED 7 (POWER ON) is off :( UPDATE #2: I removed both the RAM Risers, to check whether the machine would blink or chime (to show no RAM). I switched on the Mac Pro and believe it or not, it still shows no change in behavior. The white light is steady, no blinking, fans spinning. I doubt if it even registered that there are NO RAMS attached to it. Should I book a coffin for it? :( [/QUOTE]
