  1. Hey, I have a weird problem. After a power surge my pc wont boot.....well thats not actually all that weird. What is weird is that if I plug it in to a different power outlet It will boot. Also if I plug something else into the old power outlet that thing will work. But the pc in question will never work in that outlet again. Anybody know why?

    Nope, never kid online. Leads to a poor understanding of dark sarcasm, the emoticons never roll their eyes quite right. I am running out of outlets to plug into. Also would it help if i told you It will also kill the specific plug on the surge protector im using as well?

    Sounds to me like the mains plug on the PC lead has become faulty in some way.
    Possible too, that a surge protector has gone 'short-circuit' or, in some way a broken or intermittent connection in the mains plug. Either way I would be replacing the mains plug and lead on the pc. Another possible is the mains outlet has become faulty/ intermittent. If using a 4/6/8 way gang, things can fall into the sockets and cause problems, especially if left on the floor all the time.

    AHH !! That makes sense; the whole object of a surge protector is to be the sacrificial lamb in place of the more expensive device(s) attached. When 'necessary', a component in the surge protector is sacrifice (ie fails).

    this is the logic for the comment re kidding;

    • a/c#1 -> computer == fails
      a/c#1 -> other device == ok
      a/c#2 -> computer == ok
    those statements imply both the a/c outlet & the computer are just find -- ergo, your mystery.

    Now add the fact
    a/c#x ---> surge protector ---> computer == fail
    and it should be clear that the surge protector has done it's job.

    Issue for you: WHY did it fail?
