Why does my computer keep restarting on its own?
Freezing or restarting by itself is usually heat, power, memory or a failing drive. On desktops in Nigeria, unstable power is a big one.
It usually needs a technician, but it's rarely an emergency. The checks below are safe to try first.
Does this sound like yours?
- It freezes or restarts by itself
What usually causes it
- Overheating from dust or a weak fan
- Unstable power or a failing power supply (desktops)
- Memory (RAM) or drive errors
Most likely first. A hands-on test confirms which one it is.
What you can safely check
- Notice whether it happens when it's hot, or when light changes to generator
- On a desktop, try it on a UPS or a different socket
Please don't
- Save your work often until it's fixed
- If the drive also clicks, back up now
