北大清华拟人:这问题真难缠！帮帮我！

安装完魔兽世界后打补丁时出现蓝屏，硬盘指示灯不停的亮，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

我重装了一遍系统，重分了一次区。

现在：
系统-运行正常，用卡巴斯基全盘扫描后无病毒
显卡-运行正常
内存-用Memtest检测后无异常
硬盘-所有盘都进行了系统自带的检查与修复，没出问题
这是我要问的：
我重新装完魔兽世界再次给魔兽世界打补丁时，硬盘总觉得要比干其它事的时候响，不过这次总算是打成功了，但在删除补丁源文件后回收站竟然是空的，好一阵才显示有未删除文件，我总觉得硬盘有点问题，但在干别的事的时候又没有异常，可能是我太小心了吧，大家给分析一下第一次打补丁时为什么会蓝屏？是不是硬盘真的有问题？新买的电脑没多长时间，硬盘是希捷160G串口的，用不用找专业人士检查一下电脑？
我的主板是InterD915GAV，什么是Sis主板驱动？我用的不是板载显卡。
