我的电脑是今年四月份装上Windows XP SP2系统的，一直用的挺好的，七月份以来，我的机子好几次出现了一个问题，我已经重装系统好多遍了，而且换了安装盘，用上几天以后就又出现同样的问题。具体问题是这样的：
机器用中间突然就成了蓝屏，而且有这样的信息：
A problem has been detected and windows has benn shut down to prevent damage  to your comruter.
IRQL-NOT-LESS-OR-EQUAL
If this is the first time you've seen this stop error screen,restart your comruter.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 problems continue,disable or remove any newly installed hardware or software.Disable BIOS memory options such as caching or shadowing.If you need to use safe Mode to remove or disable components,restart you computer,press F8 to select Advanced startup options,and then select safe mode.
technical information:
stop:0X..........
Begining dump of physical memory physical memory dump complete.contact your system administrator or technical support group for further assitane.
上面的这段意思，我开始怀疑是安装盘到期限的原因，后来重新换了盘几天后又出现这个信息，这个问题真是让我头疼，也不知道是什么原因，有哪位朋友能帮助解决一下？
