Can a PC last 20 years? A desktop computer should last at least three years, especially when properly maintained with routine software updates. However, most can survive an average of five to eight years. Generally, when a desktop fails, all you need to do is fix or replace the problematic component, and it’s good to go.
How often should you replace PC? According to Computer Hope, you should expect to replace your computer once every four years. That’s based on a cost analysis, plus the average time it takes to wear out the internal parts of the computer. Home Computer Help gives a slightly different estimate: Five years for desktops, and three to four for laptops.
How long can the average PC stay on? Theoretically, as long as your critical components aren’t constantly running at a high temperature, you can keep your desktop running 24/7. If your PC normally idles at 30C, you have nothing to worry about. You shouldn’t have any hardware problems or slowdowns.
How long do gaming PCs last? If you want to play the newest games at the best possible settings all of the time, you’ll need to upgrade yearly to keep up.
