| 762281 | 2009-04-04 23:51:00 | Well I press the power button and magically the CPU fan spins and it boots... But for some reason it doesn't happen every time and when it doesn't nothing comes up on the monitor and all other fans spin expect CPU. |

| 762282 | 2009-04-04 23:54:00 | Does the CPU fan spin all the time while power is supplied or does it still twitch and stop? Was thermal paste or similar applied to the CPU before fitting the heatsink and fan? The fan just twitches and stops The thermal paste was pre-applied to the heat sink |

| 762283 | 2009-04-05 00:03:00 | I had the same kind of prob with the other PC here this morning. Its fine when the case side/s are on. its when I take one side off (the side thats got the CPU thing on the side). It turns on but the monitor doesnt come on. It took me nearly 2 hrs (from midnight - around 2), to get the thing going again lol. Its going now, but I still dont know what the prob was. Altho, it maybe the videocard, because I put that in the PC in the bedroom. it didnt go the first time either. But did go after I reset it. But I still cant figure out why it ONLY plays up when I remove one of the sides of the case If I dont remove either side of the case, it's fine, it boots and the monitor comes on all the time |

| 762284 | 2009-04-05 00:11:00 | Sounds like similar a my problem but does the CPU fan spin? I'll check to see if I have a case reset option in the BIOS on |

| 762285 | 2009-04-05 00:16:00 | Yup the CPU fan spins, the reset button is on the front of the case,its not an option in the BIOS This prob may have been a hdd cable prob or something. Since when I turn it on, the hdd led comes on then stops. Normally once it comes on, it stays on, till windows has loaded |

| 762286 | 2009-04-05 00:59:00 | The fan just twitches and stops The thermal paste was pre-applied to the heat sink Thats sounds a lot like Smart Fan control - Some Motherboards have that and what happens is the Fan "kicks" when you first turn on the PC, then wont start until the CPU get hot enough , then the fan will start up, as soon as the CPU is cooler, the fan slows down again - quite often you will hear the fan suddenly give a Whirrrrrr - then slow down. When this first came out I panicked - seeing it for the first time :lol: To stop this - you enter the BIOS and on Gigabyte Boards look under health - smart fan Control - alter the setting to disabled - fan will run at a consistant speed now. ( Edited in: try this anyway - sometimes SFC can play up causing a board not to boot) But for some reason it doesn't happen every time and when it doesn't nothing comes up on the monitor That is NOT Smart fan control ( normally) - have you tried setting the BIOS back to default settings. Suggestion: Remove the board from the PC, as well as the PSU - assemble it on a bench - have attached the PSU, HDD, CPU ,RAM, Graphic Card, KB/Mouse, Monitor. Locate the two pins the on button attaches to - short them with a screw driver, ( same thing the on button does) the board should boot up and load windows, try this several times, if it doesn't fail then the problem could be when the whole thing is assembled in the case something is shorting - and by moving the case slighly causes the short to not activate- doesn't take much sometimes. If it still does it out of the case , the motherboard may be DOA - and faulty - that happens sometimes. If it was sent back as faulty - what i have just described on testing is basically what the Repair center does - then if it fails for them, then they dig deeper. |

| 762288 | 2009-04-05 01:24:00 | Will try what you say wainuitech Have tried default BIOS settings and doesn't help |

| 762289 | 2009-04-05 03:07:00 | Sadly the same old story CPU fan doesn't go graphics card does:badpc: What you reccomend I do next |

| 762290 | 2009-04-05 04:29:00 | The smart Fan control Disabled in the BIOS ? Edited: try this - go into the BIOS, under "PC health Status" - make sure CPU Smart Fan Control is set to disabled ( default is Auto) then look for "CPU Fan Fail Warning ( 4th one above Smart Fan Control) - by default its disabled - enable it. Save the settings and reboot - when the PC reboots - if the CPU fan is not responding you "Should" get a warning beeeeep - if it doesn't beep or some sort of warning I'd say theres a possible board fault. |
