It wont start! replaced the battery just today it is hooked up my right, but i get nothing but lights and gages. it wont even turn over to start. it makes a buzzing sound but nothing happens


The buzzing sound is coming from the relay on the system .

The problem you have is caused by either a low charge on the battery, corroded battery connections, or a faulty battery cable. You may have a new battery but it may be well down on power. Get a battery charger, disconnect the new battery and charge the battery slowly for 12 hours or so and retry. Also make sure your cable connections at the battery are perfectly clean and free of corrosion and are firmly clamped to the battery terminals.

My HP A6400f pc has started to not want to turn on. It makes this wierd buzzing noise sometimes, monitor says video cable connected and then some times it wont even let me manually turn it of I end up...


Hi, mtmj8,

Can you tell whether the buzzing sound is coming from the power supply fan, the disk drive, or maybe an internal fan? I can't imagin it's the power supply fan, as the whole system would likely just cut out.

If it's an internal fan (CPU fan of graphics card), the system will come up to some random point before a component overheats, and usually the device will cut out in order to protect itself. You may be lucky and simply be able to replace the errant fan, or you may have to replace the component itself. Only if you feel confident enough, you may try to open the case and see if you can tell better which component is failing; take all precautions when operating a system with the case opened, and ensure that you do not touch any internal parts even while the power is switched off, as power supplies can retain a charge even when switched off and unplugged from the power supply.

If the buzzing sounds a bit "clunky", it may be your hard drive that's failing, in which case, the prospects for recovery are limited - you will probably have to replace it and reinstall the operating system and any software you have.

MB green light on but won't start


your power supply must be exact and both power connections to the motherboard must be connected. the green light will come on if voltage is supplied but will turn on a low voltage alarm which is a buzzing sound. or it just wont do anything

Vizio GV42l buzzing


Vizio makes an ok LCD, but if you notice they no longer make plasma. they stopped last year. Anyways. the buzzing sound is semi serious, it sounds as though you have a capacitor leaking. It is best to get it fixed before it goes out all the way, with it buzzing it will be easier to identify. Best of luck

Fan not blowing


Even when the power is off at the unit outside the thermostat will supply power to the contactor of the outside unit. This may give a hum or buzz as you stated. If when the power is on to the outside unit the fan tries to start but only hums the motor may be bad. Does the compressor start and run?
