如何保護機箱以及延長電腦的使用壽命

如何保護機箱以及延長電(dian)腦的使用(yong)壽(shou)命 
　　時下，不少(shao)有條件(jian)的(de)家(jia)庭均購置了家(jia)用(yong)(yong)電腦，面對(dui)這種價格不菲的(de)產品，怎樣延(yan)長其(qi)使用(yong)(yong)壽命呢？有關專家(jia)建(jian)議，應(ying)注意做到以下幾個方面： 
　　防高溫家用(yong)(yong)電(dian)(dian)(dian)腦連(lian)續使(shi)用(yong)(yong)時(shi)間過(guo)長，機(ji)內(nei)溫度上升(sheng)，熱(re)量難以散發，會(hui)造成半導體材料老化，電(dian)(dian)(dian)路出現短(duan)路等(deng)故障。因(yin)此，使(shi)用(yong)(yong)時(shi)間不宜超(chao)過(guo)4小(xiao)時(shi)。如(ru)果使(shi)用(yong)(yong)   超(chao)過(guo)4小(xiao)時(shi)，中間可關機(ji)休息(xi)片刻(ke)，讓(rang)電(dian)(dian)(dian)腦降溫。為了避(bi)免電(dian)(dian)(dian)腦過(guo)熱(re)，不可讓(rang)陽光直接(jie)照射，   不近暖氣、電(dian)(dian)(dian)爐、空調等(deng)熱(re)源。一般說(shuo)來，家用(yong)(yong)電(dian)(dian)(dian)腦的(de)環境溫度在16℃~26℃為宜。 
　　濕室內(nei)過分潮濕會(hui)使(shi)機器表(biao)面結(jie)露，引(yin)起機內(nei)元件焊點引(yin)線銹蝕(shi)發霉，造成斷(duan)路或短路。磁盤(pan)也(ye)會(hui)因濕度不宜(yi)而霉變(bian)，致使(shi)所存(cun)信(xin)息被破壞。同時，使(shi)用發霉磁盤(pan)對驅(qu)動器也(ye)會(hui)造成損壞。因此，在霉雨(yu)及陰雨(yu)天(tian)里(li)，應經常對其通電加溫，以驅(qu)除電腦內(nei)部濕氣。 
　　防低(di)溫家用(yong)電腦在0℃以下往往就(jiu)不(bu)能工作，也容(rong)易發(fa)生(sheng)故障，如要使用(yong)，應采用(yong)熱空調保溫，使其能在正常溫度(du)下工作。 
　　防(fang)煙(yan)塵(chen)(chen)煙(yan)塵(chen)(chen)是家用(yong)電(dian)(dian)(dian)腦(nao)的大敵，它(ta)(ta)有可能滲進(jin)電(dian)(dian)(dian)腦(nao)   重要的儲存設備——硬盤(pan)，對硬盤(pan)造成的損害。因此，使用(yong)電(dian)(dian)(dian)腦(nao)時(shi)(shi)，   禁止吸煙(yan)；電(dian)(dian)(dian)腦(nao)用(yong)過之(zhi)后，   好讓它(ta)(ta)稍涼(liang)一會兒，再蓋上防(fang)塵(chen)(chen)罩；當屏幕積塵(chen)(chen)太多(duo)時(shi)(shi)，   好用(yong)無(wu)水(shui)酒精棉球從屏幕中心向外(wai)擦拭；鍵(jian)盤(pan)、機箱也(ye)要定期(qi)除(chu)塵(chen)(chen)。除(chu)塵(chen)(chen)工作應(ying)在(zai)斷電(dian)(dian)(dian)下(xia)進(jin)行(xing)。 
　　防噪聲所有噪聲源如馬(ma)達的(de)轟鳴、機械(xie)震動、汽笛、以(yi)及音箱的(de)開機等都(dou)會影響電腦的(de)運行，而且(qie)易致數據丟(diu)失和(he)傳輸(shu)錯誤(wu)。因此，電腦應(ying)放在安(an)靜的(de)地(di)方。 
　　防震動電(dian)(dian)腦(nao)內部(bu)部(bu)件多為接插(cha)件或機(ji)械結構，在(zai)震動條件下會使其(qi)松動，以(yi)致影響整機(ji)工(gong)作。因此，家用(yong)電(dian)(dian)腦(nao)宜放置在(zai)工(gong)作臺上避免(mian)受(shou)震。 
　　防磁不可將電腦放置(zhi)在彩(cai)電、組(zu)合音(yin)響、電話、電風扇等帶有磁性的(de)物品周圍。因為它們(men)在工作時會產生電磁場(chang)，會導(dao)致磁盤上的(de)信息遭(zao)受損害。 
　　防電(dian)(dian)(dian)壓波動家用(yong)電(dian)(dian)(dian)腦(nao)一般宜在220V±10％的(de)電(dian)(dian)(dian)壓條件下工作(zuo)，電(dian)(dian)(dian)壓過(guo)高(gao)或(huo)過(guo)低都(dou)會使電(dian)(dian)(dian)腦(nao)過(guo)載(zai)或(huo)失控(kong)。所以(yi),有條件的(de)家庭   好配備穩壓電(dian)(dian)(dian)源(yuan)和不間斷(duan)電(dian)(dian)(dian)源(yuan)UPS。電(dian)(dian)(dian)腦(nao)電(dian)(dian)(dian)源(yuan)與家用(yong)電(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)源(yuan)應(ying)盡量分開(kai)，以(yi)減少電(dian)(dian)(dian)器(qi)起動電(dian)(dian)(dian)壓、尖峰電(dian)(dian)(dian)流(liu)對電(dian)(dian)(dian)腦(nao)的(de)波動沖擊。 
　　防雷(lei)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)腦(nao)是   怕雷(lei)擊的(de)電(dian)(dian)(dian)(dian)子(zi)設備，因為(wei)電(dian)(dian)(dian)(dian)腦(nao)對雷(lei)電(dian)(dian)(dian)(dian)釋放的(de)靜電(dian)(dian)(dian)(dian)無(wu)抗拒能(neng)力，常常由(you)于(yu)靜電(dian)(dian)(dian)(dian)的(de)干擾(rao)使電(dian)(dian)(dian)(dian)腦(nao)元件出現不(bu)容易查找的(de)故(gu)障。所以，電(dian)(dian)(dian)(dian)腦(nao)用(yong)戶(hu)不(bu)僅要有建筑(zhu)物避雷(lei)裝(zhuang)置的(de)保(bao)護，   好還(huan)要專門為(wei)電(dian)(dian)(dian)(dian)腦(nao)配備一個(ge)可防大氣感應電(dian)(dian)(dian)(dian)的(de)消雷(lei)器，也可在電(dian)(dian)(dian)(dian)腦(nao)房間鋪上地(di)毯。盡管如此，遇到雷(lei)電(dian)(dian)(dian)(dian)交加的(de)惡(e)劣天氣，   好不(bu)要使用(yong)電(dian)(dian)(dian)(dian)腦(nao)，并(bing)應拔掉電(dian)(dian)(dian)(dian)腦(nao)電(dian)(dian)(dian)(dian)源的(de)插頭(tou)，以保(bao)   。 
　　防病(bing)毒(du)電(dian)腦(nao)(nao)一(yi)旦感染病(bing)毒(du)，輕則(ze)影響電(dian)腦(nao)(nao)的(de)(de)正常工作，重則(ze)磁盤數據，使整(zheng)個電(dian)腦(nao)(nao)系(xi)統(tong)崩潰。因此，電(dian)腦(nao)(nao)   要防病(bing)毒(du)，其方法主(zhu)要是做(zuo)到專機用(yong)專盤，拒用(yong)他人軟盤；對新(xin)購(gou)買(mai)的(de)(de)系(xi)統(tong)和軟件，   進行病(bing)毒(du)檢(jian)查；系(xi)統(tong)中重要數據要定期備份；不(bu)讓電(dian)腦(nao)(nao)執(zhi)行來歷不(bu)明(ming)的(de)(de)程序(xu)等。
