Yes, either cooling fan, or believe it or not, your CDROM, spinning if you have it set to check CDROM as one of your initial boot devices

Fisher&paykel ,smart drive excellence 7 .5 ,the washing machine stopped working during the pumping out of the water.no power on the top panel and a slight humming noise


What is it? No power to panel or slight humming sound which indicated there is power? Can't be both. I would suggest that the humming sound if you put it on spin, will be the drain pump trying to go. If pump is left humming like that it will get hot & shut the power off until it cools down again. Pump hums when it has a blockage & can'y spin. Clear the blockage.

When computer sitting unused and then mouse is


The humming might came from the exhaust fan inside the power supply or the exhaust fan of the tower housing case of your desktop, there must be some loose screw, also check the Processor fan.

Is it ok to lay this computer on it's side?


Hi,

Yes you can lay the computer on its side. With it facing towards you carefully lay it on it's right hand side and don't place anything heavy on it while it's on it's side.

Many Dells are designed to stand up or lay on their sides, it should be safe and won't cause you any trouble.


Regards.

My new acer aspire tower has an anoying hum. Is this normal?


Hi Rick,

Ideally there will be some amount of noise emanating from any system, so its normal. The noise factor can be attributed to various components within your tower. Typical components that generate noise are:

CPU Fan - It usually runs at a speed of 1500 rpm
Hard Drive - There are circular metallic discs in the hard drive which run at a speed of about 7200 rpm for normal hard drives
Video Card Fan (if there is one)
SMPS/Power Supply fan

However, if the noise is very audible then you can try the following:

- Ensure that your tower is kept on a flat surface
- There are no obstructions around the power supply fan (found at the back of your tower)
- Power supply provided is proper and coming through a spike buster

If you feel that the noise level is high, then I would recommend contacting Acer support as it may be a problem with one of the fans or the way your motherboard has been fixed within the tower.
