我的台式机原来安装的win10系统,跑起来嗖嗖的,硬件没有什么问题,自从使用Ｕ盘安装了Ubuntu14.04之后，进入Ubuntu就会出现各种各样的死机情况,写代码会卡,打字会卡,上个网也能卡。电脑卡的时候任何设备都不能使用,也不能ctrl+alt+F1跳转到tty。请问我要如何解决?是显卡驱动的事么？网上给了一些答案但是太不靠谱了。这个是我最近一次死机的日志,是按alt+table键的时候死机的,当时电脑只开了sublimetext 编辑器和chrome(chrome里也没有视频和flash)。

Start and run from the USB flash drive to see if there is any lag
If the card is caused by the hardware driver, choose 15.10 or other newer versions and try again
If it is not stuck, it is a problem with the original win partition. You can choose to reinstall. When reinstalling, choose to install to the entire hard disk to overwrite the shipped win
If you don’t know about LVM, you don’t need to select LVM when installing. Otherwise, because the system is installed into LVM, you will not be able to upgrade or restore the system from the USB disk later
