Ok i am trying to determine what else would cause a PC to not power on after a storm... Lady brought me in her HP S5000 and said it wouldnt turn on after she got home and the power had been knocked out by a storm...  I plugged it in and sure enough NO power, not even a surge to kick on the fans momentarily... I checked the PSU on my tester and it seems to be fine (dont have voltage readings, but all the lights lit up except the -5v rail), i made the call then that it was most likely the mobo as all other components *beside CPU were tested and working in another.


I know from my experience there are only 3 major things that will prevent PC from turning on.. PSU, Mobo, or CPU.. (bad power switch also, but that is not the likely culprit here)

If i recall even with a bad CPU i should still get power to the mobo and fans should at least kick over once, correct?


I really hate being wrong about it being the mobo as it cost almost $100 to replace.


Any advice would be greatly appreciated
