Hello,
a faint metalish sound is heard on starting my pc. i thought it to be some some loose metal piece (case cover , ...) this is accompanied by a whirring(fan) -like sound. this whirring like sound is heard sometimes long after booting up . tried to locate the source of the metalish sound. removed the case cover,tightened the screws,... .no avail the noise still persists.as for the whirring sound, tried stopping the case-fan,cpu fan to pinpoint the source . again no luck. read it some where here about the possibility of it being the psu fan. could u help ? the system runs fine. heating is not an issue. the new mobo is gigabyte.new processor athlon 4600+ sysytem very silent after a couple of minutes of booting up. power supply 400 watts
The best thing i can sugest is to check all screws are tight and not just the ons on the motherboard as these have a tendancy to come undone slightly due to the cpu fan and I would also upgrade the powwer suply to a 500 wat or above as the mother board is drawing more powaer during boot up and if noise is still heard then get the case sound proofed and chack for vibration of pc also make sure it's on a level surface as this will thow the fans out during boot and check all cables are fully pluged in if you find any that are slightly loose for example the data cable to the hard drive and cd/dvd burner get this replaced as this will help with your boot up speed as the pc checks for devices connected during boot up.
hope this will help you
Try this remove side cover and boot computer listen for any extra noise fan etc. also by power supply
As I think you have a bad bearing in a fan
To temp fix it
remove paper cover over center of fan and put a small and I mean small drop of light machine oil on bearing then replace paper cover.
check if this stops the noise if it does you know which fan to replace.
If it is power supply fan and if you think yourself capable remove fan and do the same to it

hello,
no noise from cpu fan, case fan for sure. as for the power supply do you think the above mentioned noise could be caused by the fan or could it be something else in the psu.should i change the psu in case the noise doesn't stop or except the "noise" the problem hardly matters. as i mentioned earlier the noise goes away after some time. ty
