| 335496 | 2005-03-18 20:40:00 | I built my new system about three months ago, here are the specs: Athlon 64 3400 Gigabyte K8NS Pro Motherboard 1 GB DDR400 Western Digital 200GB Western Digital 120GB NEC 3520A DVD Burner Generic DVD Burner Powercolor Radeon 9550 256MB AGP Case Has A PowMax 400Watt Power Supply Windows XP Pro SP2 The problem is that yesterday, I went in to my computer room and the computer was off. Thats odd because my computer is nearly always on. So, I hit the power button and the case fan and my CPU fan just turned about a quarter rotation and then stopped, and the computer was off again. Hmm, so I pulled to PS out and put it in another PC that I have and it seemed to work just fine. I only tested it for about 15 minutes. So, I put the PS back into my system and it started up just fine. Wierd. After that, the computer ran just fine for about 24 hours then today, I went to use it again and it was off. Damn. This time, I hit the power button and it started just fine. I figured while the computer was running, I would see what the temps and voltages were. Well, while I was writing this the first time, the computer just shut off on me, so I'll try to remember what the specs were. Motherboard temp: 29C CPU Temp: 30C HDD1: 30C HDD2: 25C +12V = +11.90 +5V = min +2.64V max +4.73V Core = +1.60V Aux = min +2.61 max +2.62 All these stats were under no load, they remained pretty much constant for at least the half hour that the computer was on. I'm thinking that somehow that motherboard got fried or something like that or the Power Supply is bad. I'm not really sure what else would cause it to just shut off like that. I know that heat will do it but that doesn't seem to be an issue. I've never seen the CPU temp get over 40C even right after playing Doom III. Any help would be great. Thanks. |

| 335497 | 2005-03-18 20:44:00 | In your BIOS is the auto-shutdown feature for overheating set too low? | Greg (193) | ||
| 335498 | 2005-03-18 20:57:00 | I just checked it and its set at 50C so I don't think thats the issue. I was thinking that maybe the software was reporting the CPU temp incorrectly but the BIOS reports the same temp as the software under windows does. I've shut off pretty much every thing else that would wake, or shutoff the computer without pressing the power button. Don't know whats wrong, I feel like this: :badpc: :badpc: :badpc: :badpc: | Lowlyfe45 (7642) | ||
| 335499 | 2005-03-18 21:08:00 | Could be the software/hardware switch on the motherboard, the one that windows use's to turn your computer off is playing up. I have known this to happen. Trevor:) |

| 335500 | 2005-03-18 22:20:00 | I had a client computer doing the exact same thing just before xmas. A brand new computer and the dvdr was faulty causing this problem. What i would do is to disconnect everything just plug power supply into m/b and check if it boots, if ok then add each peripheral and hopefully you will find the cause. GL | Loppy (7632) | ||

And in case it's a software issue, try a similar trial and error by going into msconfig and disable each item one at a time (or visa versa, disable all) and one by one re-enable them. |

| 335502 | 2005-03-18 22:37:00 | In your BIOS is the auto-shutdown feature for overheating set too low? Another long shot could be... perhaps your motherboard has a temperature control/monitoring application that could be set too low. |

| 335503 | 2005-03-18 22:38:00 | try and do a virus scan, maybe its the blaster virus? | Prescott (11) | ||
| 335504 | 2005-03-18 22:53:00 | So, I hit the power button and the case fan and my CPU fan just turned about a quarter rotation and then stopped, and the computer was off again. Shouldnt be software related because the computer fan turned a quarter of a rotation so the computer hasent even POST'd, so that should rule out blaster and any software issues. Dunno about the motherboard temp auto shutdown feature tho... but i would have thought that the p/s would still be running..... |
