Best desktop PCs for reliability
A good PC can last you longer than any other computing device, with additional card slots offering you the opportunity to upgrade the PC rather than replace it completely in order to keep up with the fast pace of technology. But some PC brands are more prone to problems than others, with common issues covering everything from a hard disc failure to a frozen screen. A new PC is a substantial investment and our survey will help you choose a brand that you can rely on.
In our survey we cover all the major brands, such as Compaq, HP and Dell, as well as Apple, asking thousands of Which? members if their machine has needed to be repaired and why.
Based on a survey of 12,691 Which? members in September 2013. Reliability score is based on models purchased in the last six years. Previously owned models are also taken into account for those who purchased their current model to replace one with a fault. Customer score is based on satisfaction and the likelihood of recommending the brand to a friend.
Common desktop PC problems
From our survey of 3,461 desktop PC owners, 17% told us their PC had required repair. Out of all of the Desktop PCs that experienced a problem - whether it was repaired or not - these were the top three issues.
- Screen started freezing (17%) - low or faulty RAM (memory) could be the cause.
- Spontaneously rebooting or turning off (9%) - this could be caused by a faulty fan and the PC overheating.
- It won't boot up (8%) - this could be an issue with the hardware if it won't come on, or the operating system if it gets stuck during the boot process.
