跪求联想B450开机死机、花屏、蓝屏解决办法，谢谢！

电脑昨天突然出现花屏，重启多次都是花屏，通过一键还原，依旧不能解决。后来，还出现蓝屏，显示如下：最近电脑偶尔出现花屏和蓝屏！蓝屏的时候出现下面的一些文字，谁能告诉我这是什么问题啊！谢谢大家了~~~A problem has been detected and windows has been shut down to down to prevent damage
to your computer

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
these steps:

The device driver got stuck in an infinite [url]loop.This[/url] 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.

请求高手处处招啊，谢谢了

Answer 1

一般来讲是显卡的问题，而显卡的故障大概有：
1、损坏
2、驱动坏或版本低
3、过热自保
其中3和2的问题可能性最大。
建议：
1、清理机器内部的积灰，更换导热硅脂
2、更新显卡驱动和电源管理驱动
3、清理系统垃圾、减少不必要的开机启动项----使用360完成
4、不同时运行过多的程序和打开过多的网页
