dnf金色曲玉有什么用:电脑蓝屏，出现严重错误，救我！

安装完魔兽世界后打补丁时出现蓝屏，显示：
A problem has been detected and windows has been shut down to prevent damage to your computer.
The problem seems to be caused by the following file: SISGRV.DLL
PAGE_FAULT_IN_NONPAGED_AREA

If this is the first time you've seem 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 problems continue,disable or remove any newly installed hardware or software.Disable BIOS memory options such as calhing or shadowing.If you need to use safe mode to remove or disable components,restart your computer,press F8 to select Advanced startup options,and then select mode.

Technical information:
***STOP: 0x00000077(0x0000000E,0x0000000E,0x0000000E,0x11D4000)
***SISGRV.DLL-Address BFA33A40 base at BF9D3000,Dtestamp 00000000
现在：
系统-运行正常，用卡巴斯基检测后无病毒
显卡-运行正常
内存-用MEMTEST检测后无异常
魔兽世界-无法运行，无法卸载，无法删除，不过重起了一下电脑总算它给格掉了
硬盘-主要怀疑对象
大虾们给小弟解释一下吧！先谢谢了！
