电脑换了个电源之后就开不起机了。

电脑电源坏了然后找了个维修部换了个，换了之后那个人试了下，说可以了（电脑开了一下，就听了一声响，那个人自己觉得好了）拿回来后，电脑连系统都进不了，开机就显示A problem has been detected and windows has been shut down to prevent damage to your computer.

If this is the first time you've seen this stop eror screen, restart your computer. If this screen appears again, follow these steps:

Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated.

Run CHKDSK /F to check for hard drive corruption, and then restart your computer.
