One of the simplest ways to boost your computer's lifespan is by upgrading its RAM. Increasing memory can significantly improve performance, especially if you use resource-intensive applications or multitask frequently. This upgrade allows your system to handle more processes at once, which can prevent slowdowns and crashes, ultimately extending the usable life of your machine.

Another effective upgrade is replacing your traditional hard drive with a solid-state drive (SSD). SSDs offer faster data access speeds, which can make your operating system and applications load quicker, leading to a smoother overall experience. This not only enhances performance but also reduces wear on other components, helping your computer run efficiently for a longer time.
