Common desktop PC problems
From our survey of 4,500 desktop PC owners, 19% told us their PC had required repair. They also told us what the problem was. The most common issue was a hard disc failing. Hard discs do have a certain lifetime and this problem will be directly related to the quality of the hard drive fitted by the manufacturer.
- Hard disc failed (21%) - this can be due to age, but also overheating or a loose circuit board
- Screen started freezing (7%) - low or faulty RAM (memory) is often the cause
- Spontaneously rebooting or turning off (4%) - this can be cause by a faulty fan and the PC overheating
