It appears power supply AND mobo is toast.
used a different power supply, can't get any life out of mobo.
Stripped it down to just mobo, keyboard, & ram. Virtually NO life.
Keyboard light blinks sometimes, case PW Led stays on and dim all the time, thats about it.
About 3 yr old which I understand is is about the life expectantcy.
If mobo is toast, whats the chance the CPU is still good?
General guess on cost to replace PS, mobo (& maybe CPU)
My thought is to just trash the machine and recycle what parts can be used.
