| 306579 | 2004-12-22 01:02:00 | Tried the stethoscope idea but i couldn't tell at all where the noise was coming from, dont think its the psu though. I rolled up some paper into a tube but i was only getting the low frequency noise through my ear. Whetu, you mention an interesting point about the capacitors. I noticed earlier today that some capacitors had some browny rust like substance on the tops, I took it off some of them but left it on a few. I'm not sure that removing the substance would do too much good but i might give it a go. If it is the capacitors does that mean that it is a problem with them getting charged up? |

You've been hit by the dud cap scandel, cheap Taiwanese capacitors were snapped up by a number of board manufacturers . Much to their embarrassment and cost (for replacement items), the caps started expanding and leaking (brown stuff) . How old is the board, what are you consumer protection laws like . Contact the retail source and try for a replacement, they'll have been well aware of this issue before now . Have you backed up your data? Spotting Whetu :D |

| 306582 | 2004-12-22 15:24:00 | Yeah I cleaned off all the electrolyte but it made no difference. The board is slightly over 3 years old, I'll try and see if I can get a replacement from the manufacturer. Talking about cheap components, I had two 40gb Fujitsu drives that failed because of some cirrus logic chips that melted. Fujitsu wouldnt give a replacement even though the issue was well documented. However I was able to salvage my data using a recovery tool I found off the net. The tool was made by Fujitsu but god knows why they didn't make it freely available. If I have to buy a new motherboard, do you think I will be able to get one that is compatible with the processor and other components? |

| 306583 | 2004-12-22 21:29:00 | Do u have any female/male power adapters in the case? ie: for extra devices? These things dont last long sometimes . As sometimes the wires in these can get loose . And as u mentioned, the power on/off button wont work . And if one of these are connected to the main hdd, (or any of the devices), and the wires arent in the whole way, (on the adapter), well obviously it wont boot . This happens to this case once in a while (as u mentioned too) . I have to open the case, and check the wires to these adapters . I know when its fixed coz I'm then able to use the power button to turn the system back on . |

| 306584 | 2004-12-23 16:23:00 | So you think I should try fiddling about with the power adaptors to see if that makes a difference? I'll try it and see if it makes any difference. |

| 306585 | 2004-12-23 17:44:00 | my vote goes with capacitors......... | drcspy (146) | ||
| 306586 | 2004-12-23 23:34:00 | I think capacitors too. Bletch |

| 306587 | 2004-12-24 04:28:00 | Hmm just read this on the herald site in inbox . Whats the refresh rate on the monitor?? Sally's monitor is making a high-pitched whistling sound . "Recently my cousin changed a setting to do with my display and now the monitor screams at me . It's not loud but very irritating . Is its life at an end, or is the noise caused by a reversible setting? A: Change the display refresh rate, Sally, as some monitor transformers resonate at certain rates . Right click on Desktop/Properties/Settings/Advanced/Monitor and select a higher refresh rate from the dropdown menu - 75hz is a safe bet for most modern monitors . A higher refresh rate produces less flicker and therefore less eye strain . But don't lift the rate too far as some monitors won't support high refresh rates . |

| 306588 | 2004-12-24 06:39:00 | Speedy, that would suggest a variable refresh, becuase the noise is not there all the time?? Also doesn't cover the reboots. | Murray P (44) | ||
