It's worth exploring all possibilities with voltages, then I'll know what to look for on our end.

I put Vcore to 1.37 and PLL was 1.85. Same symptom, CPU LED stays on then shuts down. I'm keeping the VCORE at 1.37, and now I bumped the PLL to 1.90. Is 1.9 PLL too much??? I have not touched VCCSA, since I have no idea what that does.
I have BIOS 0603. Is this too old? Should I update? 906 IMproves system stability. Does this have anything to do with me? Like I said in my original post, I had the same issue on a different board with the updated 906 BIOS.
