| 325947 | 2005-02-17 11:19:00 | I recently altered my case to an Xblade with a 450 Watt PSU. I have an MSI 6777 motherboard with athlon 2600+. Upon installing the whole lot i put the power socket in and immediately the whole pc started up, lights, fans and all. When i shutdown the PC the lights and fans (both CPU and non) stay on even though the CPU is off. I have tried changing back the PSU and the case and the problem remains so i can only assume the motherboard was damaged despite all my safety precautions. I was wondering if anyone had encountered this before or if anyone has any ideas on how to fix it because it means i have to switch off my pc at the wall every time which is less than ideal PS, i cant really afford a new motherboard. |

| 325948 | 2005-02-17 18:44:00 | I would make sure the fans (CPU or other), are plugged into the right connection/s on the mobo. How or what are the fans connected to?? A power supply connection, or to the motherboard 3 pin connections??? Make sure the CPU fan especially is connected to the CPU fan 3 pin on the motherboard. Sounds like you've connected something to the wrong place somewhere, on the mobo. When u changed the case. I would check the connections, to the power and to the case, and your manual, if u have one. |

| 325949 | 2005-02-17 19:02:00 | Are you sure you're putting the switch, speaker and LED connecters on there correct pins on the motherboard? What are the BIOS power event settings? What are the settings in Control Panel > Power Options? look at the Adavanced tab, what does it say in the drop down list for "When I pussh the power button on my computer"? Do you have a UPS? |

| 325950 | 2005-02-17 19:09:00 | The CPU fan is conected to the square pin from the PSU, the other fans are plugged into the vacant molex from the spare that goes to the hard drive, but removing or adding them doesnt seem to make a difference, thats whats so frustrating. If the power is on then the fans all go round and turning off the pc makes no difference. As for the Power settings the pc is set to turn off when the button is pressed which is what leads me to think its the Mobo because the proccessor doesnt seem to continue to run when the fans are on. Live in the UK so no UPS Not sure about the plugs for the buttons but i did follow the Mobo instruction guide i think. Thanks for helpin though guys cause im at my wits end, any other thoughts |

| 325951 | 2005-02-17 19:18:00 | The cpu fan SHOULD be connected to the connection labelled CPU_FAN on the motherboard . If the CPU fan has a 3 pin connection on it . Connect the CPU fan to the mobo . See if that makes a diff . The CPU fan connection has got a 3 pin connection on the end of it hasnt it? If the other fans have a 3 pin connection on them as well, I would connect them to the other fan connections (if any) on the mobo . Labelled CHA_FAN and PWR_FAN or similar . |

| 325952 | 2005-02-17 19:40:00 | One fan at least has obviously got a Molex connecter Speedy, well I sincerely hope so anyway . Some boards and/or fans only have two pin (no monotoring) but, that won't make any diff to the pins on the board that you suggest they connect to (another one might say Sys) . What's the chance of having two power switches go bung on you? You checked the BIOS? If all else fails, I think you need to do some meter testing or have it tested for you . BTW, why wouldn't you have a UPS (Uninterruptible Power Suppy) in the UK? |

| 325953 | 2005-02-17 19:43:00 | The cpu fan im using derives its power from the cpu power plug which has a square 4 pin arrangement. The other fans are all 4 pin molex, but the problem with with the CPU fan continues whether the other fans are connected or not. | inshadows (7350) | ||
| 325954 | 2005-02-17 19:57:00 | Apologies i was wrong about lacking a UPS in the UK. The cpu power supply is in a square 4 pin molex arrangement (i assume the cpu fan derives power from this), all the others bar the front LED are in sequential 4 pin molexes with each attached one after the other. The action of the additional fans however i feel will sort itself out when i find the MB problem out becaues the CPU fan is always on whether the other fans are connected or not (as in until i get peeved and switch it off at the wall. | inshadows (7350) | ||
| 325955 | 2005-02-17 20:23:00 | Hmm OK . I found the manual for this mobo I think . CFAN1 on the mobo looks like its for the CPU fan . Why the CPU fan hasnt got a 3 pin connection, on the end of it, I dont know . SFAN1 is for another fan . I take it, the power supply u have is an ATX PSU . I take it also, that you've connected the 4 pin from the PSU to JPW1 on the motherboard?? To supply the CPU with a bit more juice . You have installed the videocard drivers previously too havent u?? Maybe they need updating? |

| 325956 | 2005-02-17 20:52:00 | Thats right, the MOBO manual said to attach the 4 pin plug to ensure proper ventillation of my proccessor, the graphics card is up to date as far as i can determine. | inshadows (7350) | ||
