现时,由于组装微机价格低廉、性能好、兼容性也比较强,逐渐走入了家庭.但随着组装机的逐渐普及也产生了一些问题和故障.有一用户购买了1台MX386-DX/40主机,内存4M,200M硬盘,没有认真验机,回来后出现如下现象:故障现象:开机有时能自检成功,有时却不能.自检完成后,过几分钟后机器死机.热启动、复位均无效,必须关机.关机后必须停留几分钟,然后开机,机器才能启动.分析与排除:根据故障现象分析,由于机器能正常自检并自举,说明不太可能有什么硬件设备损坏,首先怀疑是电源故障,因为有些主板的准备好信号是靠电
At present, due to the assembly of low-cost computer, performance, compatibility is also relatively strong, and gradually into the family.But with the popularity of assembly machines also produced some problems and failures.One user purchased a MX386-DX / 40 Host, memory 4M, 200M hard drive, there is no serious testing machine, back after the emergence of the following phenomena: Failure phenomenon: boot sometimes self-test success, sometimes it can not.After the self-test is completed, a few minutes after the machine crashes.Hot startup, reset Invalid, must be shut down .Shutdown must stay for a few minutes, and then boot, the machine can start.Analysis and exclusion: According to the analysis of the fault phenomenon, as the machine can normal self-test and bootstrap, indicating unlikely to have any hardware damage, first of all doubt Power failure, because some of the motherboard ready signal is by electricity
