郑州郑飞集团待遇:电脑有问题，怎么办啊，急死我了~~~~~~

我几乎每次把电脑关机后都会出现一个蓝屏，上面有很多英语，每次都要自己按电源开关才能把电脑关掉，所以很烦琐，蓝屏的英文全文如下：
A problem has been detected and windows has been shut down to prevent damage to your computer.
PAGE_FAULT_IN_NONPAGED_AREA
If this is the first time you've seen this stop error screen,restart your computer.If this screen appears again,follow these steps:
Check to make sure any new hardware or software is properly installed.If
this is a new installation,ask your hardware or software manufacturer for any windows updates you might need.
If problem continue,disable or remove any newly installed hardware or software .Disable BIOS memory options such as chshing or shadowing .If you need to use Safe Mode to remove or disable components,restart your computer,and then select Saft Mode.

我的电脑除了这关机不正常，其他的都是正常的。我的电脑的主机是2005年1月26日生产的。以前也出现过这个现象，联想的维修人员来看过，他把电脑一键恢复了，但这个现象还是偶尔出现，现在更是频繁出现，我用杀毒软件全面系统扫描过了，没有病毒，请问出现这个蓝屏到底是什么原因，怎样使它恢复正常？
我认为这是个什么程序，不是我的电脑的问题
