原是技嘉b250m的主板想升级9代i5CPU，有没有好的主板推选？

首先，换了主板和CPU基本上都是需要重装系统才行的。
不过，换之前先卸载掉主板和CPU的全部驱动，换了之后再安装上新的驱动，或许可能用不着重装系统。
要继续使用WIN 7系统，那么主板就只能选择B365芯片组的主板。CPU可以考虑i5 9400F，选择i5 9600KF的话，主板又不支持超频。
另外，你本来的i5 7400+B250主板的性能还并不算差，升级后整体性能提升并不是太大，不怎么划算啊！
1.想装Win7又想用9代i5的那就只能用B365芯片的主板了，你可以用英特尔i5 9400F处理器搭配微星B365M MORTAR主板。
2.另外，不是说B365支持Win7就一定不需要重装，因为还是存在一定系统加载不成功的概率的，所有的配置都是如此，哪怕是Win10也是一样。
3.建议你先在现在的旧电脑安装集成了最新驱动的Win7 64位旗舰版系统（可以去“吻妻官网”下载镜像，纯净的，且驱动比较全）。
