电脑硬件升级是什么意思？说白了就是通过更换和加装某个或某几个电脑硬件来实现提高电脑性能的操作，生活中很多人都喜欢给电脑升级固态硬盘硬件和内存条硬件，这样的硬件升级选择到底对不对呢？我非常负责任地告诉大家：这样升级是完全合理，但是对于普通电脑用户来说一般无需升级内存条硬件，普通办公需求的电脑4G内存足够使用，玩游戏电脑8G内存足够使用，那么电脑加装固态硬盘硬件是十分有必要的，因为固态硬盘能改变你电脑运行的流程程度，为什么这么说呢？因为固态硬盘的读写速度决定了电脑操作流畅的程度，固态硬盘除了品牌影响价格外就是读写速度影响价格了。对于固态硬盘硬件的选择我个人非常相信intel（英特尔）品牌，价格比三星品牌固态硬盘便宜，但读写速度与三星同价格固态硬盘是一个等级，我个人使用的固态硬盘型号是：intel 545S-512G。
自用的Intel 545S-512G固态硬盘
intel 545S-512G固态硬盘的读取数据速度是550MB/s，写入速度是550MB/s，随机4K读取是75000IOPS，随机读取是85000IOPS，这款硬盘厂家是质保五年，我为什么会选择512G容量呢？因为现在电脑基本上都不用机械硬盘了，128G固态硬盘首先就是容量不够用，其次就是写入速度不够完美，我为何要选择2.5英寸固态硬盘而不选择M2类型的固态硬盘呢？因为2.5英寸固态硬盘无论是台式电脑还是笔记本电脑都是通用的，这款intel545S固态硬盘采用了SATA3.0接口，6GB/s的传输速度保证了我游戏及网页的流畅运行操作，我台式电脑和笔记本电脑都是可以共用，M2类型的固态硬盘使用的局限性就比较大了，此外，我也可以把2.5英寸固态硬盘当移动硬盘使用，只需要把这intel 545S-512G固态硬盘装到移动硬盘盒内就立刻变成移动硬盘了。
大家选择固态硬盘不要乱选，准备给电脑加装或更换固态硬盘时一定要先弄清楚电脑支持哪种接口类型和芯片协议的固态硬盘，如果实在弄不清楚也不愿意去电脑实体店购买，那建议大家就直接选择通用型2.5英寸SATA3类型的固态硬盘，固态硬盘的读写速度和品牌决定了其价格，也决定了其性能，买固态硬盘我同样建议大家要做到【宁缺毋滥】，二三线或杂牌固态硬盘价格固然便宜，但性能比机械硬盘好不了多少，低读写速度的固态硬盘对提升电脑的运行速度没有多大的作用，选择固态硬盘的标准不是靠电脑店解释，也不是靠网店老板的描述，要看真实测评数据，用真实的数据说话。
就描述和图片，换显卡就好。hd5450是比核显性能还低的存在，带不动这个游戏，明显拖后腿。
建议显卡换二手gt640 特效全开流畅无压力。80左右
不懂继续问，满意请采纳。
升级个固态硬盘就好了，你硬盘坏了，不信你可以扫一下坏道
