电脑运行时间长了,往往会出现噪声,这时你应该仔细辨听,找到原因并消除它。常见原因有以下四点:一、如果是硬盘、光驱和CPU风扇带来的噪声,则可能是主板、电源的滤波电路性能不良,无法滤除硬盘、光驱和CPU风扇所产生的干扰信号造成的影响。缩短IDE电缆线和CPU风扇电源线均可减少或相应设备的影响,也可换个电源试试。 When the computer runs for a long time, noise often appears. At this time, you should listen carefully, find the cause, and eliminate it. Common reasons are the following four points: First, if the hard disk, optical drive and CPU fan noise, it may be motherboard, power supply filter circuit performance is poor, can not filter out the hard disk, optical drive and CPU fan caused by the interference signal influences. Shortening the IDE cable and the CPU fan power cable can reduce the impact of the corresponding device, or try another power supply.
