Recently dealing with a notebook，Downgraded Windows to XP for use，During the installation process, there were several automatic shutdowns，Judged to be caused by overheating，This CPU was considered quite high-end at that time，The heat it emits should not be underestimated。
在安裝完windows後，相關的driver也裝上，CPU開始不會胡亂飆速，也沒再發生關機的情形，但有幾次登入時，卻出現藍底白字，由於出現的時間不到一秒，根本看不到錯誤內容，但隱約可以看到跟Pxxx.sys這個檔有關，在windows紀錄也找不到錯誤報告的情形下，I remembered that a long time ago there was a tool that could view Windows dump files(error logs)，I immediately searched online。
I already forgot the name of that tool back then，This time, Google brought up BlueScreenView, a small tool provided by Nirsoft，Nirsoft provides a lot of useful tools，I've used more than one of them。Back to the main topic，BlueScreenView is quite user-friendly，開啟預設就會去抓"c:\windows\MiniDump"底下的dump檔，點擊相關dump，即會秀出所有資訊。
查了一下我的dump檔，果然全都跟portcls.sys有關，一开始就怀疑是否与音效驱动冲突，因为蓝底白字似乎都出现在准备播放登录音乐的那个瞬间，有了关键字，后面要调试就容易些了。
