电源故障时电脑故障 [英] computer malfuctioning when powered on

问题描述

您好，

实际上当我戴上电脑时它没有启动。我听到某种声音，好像有什么东西炸了。这是尖刺防护装置中的保险丝爆炸了。我发现主板没有电源。我更换了保险丝，尖刺护罩开始正常工作。仍然电源没有到达我的主板。因此，我改变了我的故障，最后它获得了力量。我的系统已开启。但一小时后它再次下车，现在每当我启动电脑时，我都没有。在2-3次尝试后，它开始。实际上我还连接了开的电线。 cpu的按钮到cpu上的重置按钮。因为cpu的on按钮无法正常工作。但是我使用这种安排已经2年了，而且每次它都能正常运行，只是现在我的系统出现了问题。

Hello,
Actually when I put on my computer it did not start. I heard some sort of noise as if something had blown up. It was the fuse in the spike guard that blew up. I found that there is no power supply to the motherboard. I changed the fuse and spike guard started functioning properly. Still power did not reach my motherboard. Hence I changed my smps and finally it received power. My system was on.but after an hour it again got off, and now whenever I start my pc I does not on. After 2-3 attempts it starts on. Actually I also connected the wires of "on" button of cpu to that of reset button on cpu. Aince the on button of cpu did not work properly. But I am using this kind of arrangement since 2 years and every time it used to function properly,only now my system is causing problems.

推荐答案

基本上，我认为你运气不错。



可能发生的事情是你的尖峰警卫已经出现飙升并且失败了 - 此时它似乎已经将尖峰传递到PC上（并且可能使情况更糟 - 有些人做了）。另一种可能性是你的PSU发生了故障，并且它在你的尖钉保护器中引爆了保险丝 - 事实上这比首先接收尖峰更可能。



这对你的电脑有什么影响？没什么好的。当你打开电脑时，PC没有响应表明你的PSU（可能）有问题，而且由于你已经改变了这个问题并且问题仍然存在，很可能它已经通过了峰值主板和相关组件。



之前我遇到过这种情况 - 一个PSU故障，它将计算机上的其他组件强调到了它们失败的程度。因为它们都连接到PSU输出电压...



我建议唯一可行的做法是更换电脑并使用USB磁盘盒（像这样： http://www.ebay.co.uk/itm/DUAL-2-5-3-5-IDE-SATA-HDD-DOCKING -DOCK-STAND-STATION-CADDY-USB-CARD-READER-UK- / 280935394629？pt = UK_Computing_Other_Computing_Networking& hash = item41690ded45 [ ^ ]）暂时将旧硬盘连接到新计算机以获取数据。我不会将硬盘直接连接到我的新电脑 - 我已经看到那种压力具有传染性并且也强调新组件！

Basically, I think you're right out of luck.

What has probably happened is that your "spike guard" has had a spike and failed - at which point it seems to have passed the spike on to the PC (and possibly made the situation worse - some do). The other possibility is that your PSU has failed, and it blew the fuse in your spike protector - in fact this is more likely than receiving a spike in the first place.

What has this done to your PC? Nothing good. The lack of response from the PC when you turn it on most times would indicate that there was (probably) a problem with your PSU, and that since you have changed that and the problem persists, it is likely that it passed the spike on to the motherboard and related components.

I've met this before - a PSU failure that stresses the other components on the computer to the point where they fail as well. and since they all connect to the PSU output voltages...

I would suggest that the only practical thing to do is replace the PC and use a USB disk caddy (like this one: http://www.ebay.co.uk/itm/DUAL-2-5-3-5-IDE-SATA-HDD-DOCKING-DOCK-STAND-STATION-CADDY-USB-CARD-READER-UK-/280935394629?pt=UK_Computing_Other_Computing_Networking&hash=item41690ded45[^]) to temporarily connect your old HDD to the new computer to get the data off it. I would not connect the HDD directly into my new PC - I've seen that kind of stress being "contagious" and stressing the new components as well!
