I have a Thermalake 850 PSU.  If I unplug the Computer / PSU due to a thunderstorm coming in and it is off for a period of hours, when I reconnect the AC plug, and attempt to switch it on, it is dead.  If I disconnect and move the computer near another outlet and plug in a cord, it powers right up. I can then move the computer back to the original location and plug it in and it is fine, UNTIL I need to unplug it again because of a thunderstorm..

Any Ideas?

How old is your PSU? It sounds like a problem w/the pc/PSU. Could try re-seating the power connector. Really odd. Might try swapping out another PSU. You're sure it never exhibits this elsewhere? Only at that particular outlet? Personally I'd invest in a quality UPS, if the PSU is ok.


Hope that helps,

Since I have the good fortune to live in a part of the world where electrical storms are very rare, this is not a problem I routinely consider.


However have you tried plugging something else into this socket - a lamp, a radio, anything else - just to see if that powers up at the first attempt. The fact that the computer powers up when you plug it into a different socket suggests there could be a problem with this socket. It is certainly worth checking and would cost you nothing but a little effort and would be much cheaper than replacing the PSU just on the basis that it might be faulty !
