I've a Desktop computer for almost 3 years. The current OS is Windows 10.
I have the following problems that start to become more frequent:
- My computer shut down all of a sudden.
- Sometime, before it shut down randomly, my screen is flicking to a black screen.
- Sometime, I use my computer for a whole day and nothing is happening. No Shut down.
- There are some few days my computer can't last over 1 or 2 hours before being shut down.
When I try to turn it on, the computer runs for a few seconds and then it turn off. After that, it turns on again BUT this time, I didn't press the button to turn on. It automatically turn on by itself. Then after a few seconds, it turns off. Then on, then off...
Even if I put my computer in sleep mode (or stand by), soon or later, it will shut down.
I have to let my computer off (without unplugging the power supply) for 15 minutes or more to be able to use it.
It feels like my desktop computer is running out of electricity or "battery". What could be the causes?
