系统有问题，请大侠，斑斑帮忙

启动时出现以下文字：

CAN NOT FIND A DEVICE FILE THAT MAY BE NEEDED TO RUN WINDOWS OR A WINDOWS APPLICATION

THE WINDOWS REGISTRY OR SYSTEM.INI FILE REFERS TO THIS DEVICE FILE,BUT THE DEVICE FILE NO LONGER EXISTS.

IF YOU DELETED THIS FILE ON PURPOSE,TRY UNINSTALLING THE ASSOCIATED APPLICATION USING ITS UNINSTALL OR SETUP PROGRAM.

IF YOU STILL WANT TO USE THE APPLICATION ASSOCIATED WITH THIS DEVICE FILE,TRY REINSTALLING THAT APPLICATION TO REPLACE THE MISSING FILE.

VIAGART.VXD

PRESS A KEY TO CONTINUE

按回车进入系统，出现

装载C：\PROGRA~1\COMMON~1\HFSH\USCU.DLL出错

系统找不到指定的文件

而且无法覆盖重装系统98

请问该怎么办

用系统信息查过，没有短少文件啊

不是显卡，我刚刚重新装过，
VIAGART。VXD？我用的主板南桥是VIA的，难道是主板的？
但是我试着安装VIA4IN1，出现死机，说什么什么不行
