    [sorry for my bad english]

    I just bought a new PC and have the following problem:

    When I press the power switch, the system (lights, fans, dvd) turns on for about 5 seconds and then turns off again. During this 5 seconds the monitor doesn't even power on, it remains in standby. After this happens, I'm not able to power on the PC again without re-plugging the PSU cable before. I unplug the cable, wait for the MB light to turn off, plug it back in, and (lol) without touching anything the power turns on by himself and turns off after 5 seconds. And now I try to turn it on by myself pressing the switch and.......

    A) the system starts up without any problem and keeps working normally during the whole day :D

    OR

    B) it turns off after 5 seconds (same story again) :mad:

    Sometimes A happens, sometimes B. What is going on here?

    Sounds as if your power supply is failing, take a look inside your case. What brand/model is it?

    Ah yes...skim reading is my downfall too. I tend to ignore anything subconsciously with a line/dash as its usually a sig.

    Anyway, it seems as if the PSU should be good quality. I'd run [google]memtest86[/google] for about an hour or so to check for RAM errors.
