经常死机怎么办

主机mint，做开发的，但因为工作需要QQ，微信，axure之类的，所以用vbox装了win7，但开了vbox经常卡死（机器8G内存，给vbox只分了1G），快捷键进不了tty界面，笔记本也没有sysrq键，每次死机只能重启，请问大家有什么好的解决方法吗

Linux, the kernel developed and distributed by Linus Torvalds et al, contains non-Free Software, i.e., software that does not respect your essential freedoms, and it induces you to install additional non-Free Software that it doesn't contain.
GNU Linux-libre is a project to maintain and publish 100% Free kernel forked from Linux, suitable for use in Free System Distributions, removing software that is included without source code, with obfuscated or obscured source code, under non-Free Software licenses, that do not permit you to change the software so that it does what you wish, and that induces or requires you to install additional pieces of non-Free Software.
For example , Linux contains RTL8723BS WiFi driver , realtek HD audio driver and so on
