| 333944 | 2005-03-14 08:21:00 | My PC, that normally stays on for days at a time, auto shut down last night and now will not start. When I press the 'push to start' button I get nothing but as I release the button the fans briefly jump and the speakers click. If I immediately press the button again I get nothing. If I press and hold the button for a few seconds (to release the 'flea power') then, again, as I release it the fans jump again. Following the suggestion in another thread I pulled all the PSU connectors and tried linking the green and a black socket in the motherboard plug. Nothing happens. But neither does the 'push to start' button, now I have pulled the connectors. I am still not sue if this is a PSU problem. Can someone give me some clues? Thanks Nigel |

| 333946 | 2005-03-14 08:41:00 | shorting the green wire to ground will only work if you have a standard PSU (not dell or compaq, etc) and if you have a macintosh i expect it would be completely different.... If it is a standard PSU, then the problem might be with pulling ALL the plugs - some PSU's only start if they have a load, so try connecting just the harddrive and or CD-rom and then try. If that doesn't work, then the psu may be dead, so try swapping it for a known working one from a different PC |

| 333947 | 2005-03-14 09:19:00 | Thanks Agent, That got me resolved, though I'm not quite sure how? The PSU and fan did start with your method. But the 'push to start' button didn't. So I reconnected the motherboard. The whole thing immediately restarted for a second or two and then stopped. Then I tried the 'push to start' and held for the flea power again and this time it started and booted normally. I think I will turn of hibernate for now! Thanks for your very quick help on this one.

| 333948 | 2005-03-14 11:03:00 | Have you checked the power plug in the back of the psu - may be a tad loose - I've known some plugs that need a fair bit of extra pressure beyond what appears to be fully in. | Greg (193) | ||
| 333949 | 2005-03-14 11:23:00 | Greg, Thanks for that. The power plug has been in and out a few times over the last few hours. But I will make sure. Nigel |
