电脑出现蓝屏，请大虾支招

平常看电影浏览网页都没事，就是玩天龙八部再运行其他程序就容易出现蓝屏，双开2个号就一定先花屏再蓝，请高手指教下。
我的配置是CPU          AMDX250，主板         华硕N68，显卡         盈通G210，内存         2G。
出现的蓝屏信息是：

The problem seems to be caused by the following file:nv4_disp.
If this is the first time you've seen this stop error screen,restart your computer.If this screen appears again,follow
this steps:

programming the hardware incorrectly.

我是菜鸟，请高手详细指点，拜谢

显卡驱动更新下，你的机器配置可以达到双开？

电源供电不足，

我把显卡驱动删了，用驱动精灵重装了一下就好了
