Really strange power problem

  1. I have a very strange problem with a PC that I use as a HTPC.
    It has always worked perfectly, but now when I pres the Power button, it just blinks and nothing happens.
    Then when I unplug the power cord, and inserts it again it boots perfectly.

    I have no idea what can cause this :suspiciou . One week before this started I inserted a new TV-tuner. Haupauge MCE-150... But I don't think that has anything to do with it.

    Any ideas, anybody?

    Fux0red powerswitch comes to mind...
    Should be relatively easy to fix/replace.

    I hope that I don't have to replace it. Soltek Barebone special button.
    Why does it work then, when I unplug the powercord, and puts in back in?

    When you disconnect from the mains, all is OFF.
    When you only let Windows shut down, there is still minimal power to the mainboard.

    When you now reconnect the mains, the mobo gets a "kick-start" and will spring to life.

    You could try to open and fix that button. There are only 2 wires AFAIK.
    Or go to an electronics-shop and get a cheap non-latching pushbutton switch. Connect that instead of the front pushbutton. You can always 'hide' it at the PC's back I guess.

    Problem solved, I think!

    Thanks for the replies.

    I checked the power button again, but nothing was wrong with it.

    The solution was as simple as Resetting BIOS, boot up and load optimized defaults. :blush:

    That seems to be working, but what the actual problem was, I don't know...
