thinkpad R400蓝屏怎么办？

各位大虾你们好，小弟有一事相求。08年11月我买了thinkpad R400 A17，把原装vista刻碟备份后，在美承装了IBM厂家提供的正版XP，并装了08下载版瑞星，用起来速度还可以，就是开关机速度有点慢，我已经优化了启动项，只留下Fn和硬盘防震了，但还是老样子，郁闷。前段时间我用了Thinkpad自带的System Update，更新了好多驱动和BIOS，过了几天就出现蓝屏了，无奈只能用ThinkVantage一键还原系统，并装了个人版金山毒霸，并对启动项进行了优化，基本和上次一样了，我还设置了系统还原点以防不测。最近玩网络游戏，有时候屏幕卡着不动，几秒后就蓝屏了。我还原了系统后，但这种情况还是会在玩游戏的时候出现，小弟回天乏术，现发来蓝屏字幕和错误代码，请求各位大虾赐教：A problem has been detected and windows has been shut down to prevent damage to your computer.The problem seems to be casused by the following :atizdvagIf this is the first time you’ve seen this stop error screen,Restart your computer,if this screen appears agin,following these steps:The device driver got stuck in an infinite loop.This usually indicates problem with the device itself or with the device driver programming the hardware incorrectly.Please check with your hardware device vendor for any driver updates.Technical information:*** STOP: 0x000000EA(0x859395E8,0x84D595A0,0xF7AA9CBC,0x00000001)atizdvagBeginning dump of physical memory.
