My PC Boot sequence fails at pwr on and has to have psu supply removed to reset Help?
Posted on 2004-10-11
From power off state, I have to unplug the psu to re-set the PC as after the pw button is pressed the boot fails. I note a MoBo led indicates power but this has repeatedly faded at the same time as the power cuts everything, but the USB bus (which still has a voltage the lights are on). I then have to unplug the psu, wait about 5 seconds, then re-plug in. Sometimes it goes straight to boot without an 'on' button press, other times it needs the press, then jumps between the two. I'm trying to keep the thing going full time to prevent 2-3 hours repeating the above :-( once it's booted and the drives are all running it seem ok, but ive tried running with all the drives I could have disconnected, disconnected, even floppy, (and with USB disconected at the MoBo)
I'm not sure which way to jump PSU MoBo or CPU ??
