Hope you can help me, attached a USB hub fresh from the bay, once USB was in the PC shut down instantly, like I had pulled the plug out.
Power switch does click but nothing happens. Have swapped PSU, no change, do have the small LED on the mobo on, getting 5.4v through the loom, tried shorting the switch pins but nothing, have pulled cleaned and replaced CPU, nothing.
I'm running out of knowledge and talent fast, what else to check?
This is my PC for surfing, watching films etc, doesn't see high end games or anything taxing, so it's not something I can say has been bothering it.
Dell dimension 3000, 2gb ram, audigy2, wifi card and everything else is oem, P4 HT 2.99ghz chip.
I'm game to try all that I can, your help is very much appreciated.
