| 628445 | 2008-01-08 21:51:00 | Hi, Asus M2NPV-MX mobo, 1 gig stick of ram, 300w psu, seagate hdd. Chimei LCD CMV938D When I press start button, the PC starts to light up, the 3 fans run and what sounds like the hard drive waking up.... but only for 3 seconds! Things I have tried: Clearing CMOS with jumpers, battery test. Reseat ram, reposition ram in another slot. Disconnect HDD & DVD/CD. Checked for loose wiring. What are my next diagnostic steps from here? Thankyou for your kind help. |

| 628446 | 2008-01-08 21:52:00 | Try another PSU Have you checked the case for dust?? If there's dust in the case, give it a clean. |

| 628448 | 2008-01-08 22:36:00 | Thanks for the replies, it much appreciated. The machine is 13 months old. I have cleaned all traces of dust out. Incidently, this happened first, 2 or 3 days ago and after removing/refitting battery and reseating ram, the machine booted with checksum error. I loaded defaults and it's been ok till this morning. Another clue may be an email/spam I got a week ago, promptly emailed itself to all my address book list! Scans with avg reveil no present virus though. Re: power supply. I have a number of power supplies, all from older machines. How to determine if any are suitable? I read where there should be 12V on yellow PSU lead. Is this any kind of definitive test? |

Scans with avg reveil no present virus though of very doubtful relevance as at that stage of boot process it's unlikely that any virus will affect anything since windows hasn't loaded and indeed the bios is hardly swiinging into action...... |

| 628451 | 2008-01-08 23:27:00 | Ok, well I found a 300w power supply but it has no sata connector. Will it work apart from no hard drive? ...just for diagnosis purposes? | Tbird650 (6754) | ||
| 628452 | 2008-01-08 23:35:00 | The PC should boot into the post, look for drives and stop when it complains it cant find the hard Drive, but if it gets to this stage its 3/4 of the way there. | wainuitech (129) | ||
| 628453 | 2008-01-09 00:04:00 | Another 300W psu installed and result is same.... runs for 3 seconds only. I am replacing the original PSU. What's next step please? |

| 628454 | 2008-01-09 00:07:00 | Is it beeping, before it shuts down, if the case has a speaker? Try configuring the BIOS properly. Did you put the jumper back on the CMOS jumper, after u took it off? |
