Do you mean beep? Beeping may occur due to RAM corruption (indicated by three long beeps). Failure of input or output devices may also cause beeping. first unplug the RAM, if the same beep continues, then the culprit is RAM. if not,then replug it and unplug the KeyBoard. do the same with the rest of the I/O devices. Also try to put ur processor in ur frens PC, and vice versa, then u'll know if ur processor or the motherboard is not working.

Is it NEW? Return it if in warranty time. you've used it past warranty time? Well, hope you get a better answer like mine, though I doubt it. Toys are designed to las just until warranty is over, even expensive toys, and actually I don't know about any Toy-repair Service.

Sony cybershot audio buzzing


I have the same problem, and cant seem to fix it. I know it has to do with the audio chatching the camera making the noise. Listen, take your camera and turn the function to take a video clip, then listen to your camera. Isnt it making the same noise as you hear on the video clip?

Combo Kenmore dryer buzzes when turned on. Dryer


Your dryer motor is being told to turn, but cannot. One possible reason is due to lint build up on the motor shaft.

Here is how it works: the motor has a set of starter coils, and a set of running coils. There is a momentum actuated sliding switch on the shaft. When the motor starts from the normal rest position, the spring loaded switch on the motor shaft makes contact with the set of starting windings on the A/C motor. When the motor reaches a certain speed, the momentum of the motor causes weights on the collar to try to move outward. Through this outward movement, the force is directed through a mechanism which moves the collar on the shaft to the other set of contacts for the running coils of the motor.

In some cases, lint builds up on the motor shaft and can cause the sliding switch to lock into place instead of being able to slide back and forth. If the collar is locked into place over the running contacts, you could get this buzzing noise. The motor is trying to run, but doesn't have enough torque to start, and therefore will sit and buzz....

Loud buzz when starting, then shutting down after 10 min.
