Mac Pro 2006 Boot Issue

2006 Mac Pro 1,1, won't turnover on power on. CPUa/b overtemp lights illuminated on logic board along with only trickle power. No other diagnostic lights turn on including power on, which leads me to suspect I have a PSU malfunction.

I'd appreciate any feedback!

Mac Pro 3.1 (2007)

I'm having the same problem. Did you find out if it was the power supply?

Many possible issues, ranked by most likely:

Power Supply

Motherboard

CPU failure

Have you tried having NO memory in there, just for diagnostic sake? Perhaps remove the memory risers and see what happens? I know it sounds weird but sometimes any symptom can be useful. I would also disconnect any drive from the computer, hard disk and optical drive.

Best of luck,
