[SOLVED]820-4924 power cycling

[dukefawks]

Like I said, anything can cause power cycling. It is just the CPU not starting and the machine trying again and again.

But what about when I getting cpu vcore but the machine wasn't chiming or the screen wasn't turning on. Could Q7310/11 caused that?

if you get S0, do you get ALL_SYS_PWRGD?
I notice you mentioned you messed with u1950. if improperly soldered or not working correctly it could cause All S0 but no chime.

The machine is now working and all rails are present I was just asking to keep as a mental note
