Dear Computer Lady,
Lately my computer shuts down while I’m working on it and I have to press the power button to get it back on. Sometimes it does it a couple of times. I’ve noticed it also turns itself on after it’s been shut off for a while.
Ghosts? lol. Or is it a hardware problem?
This sounds like a hardware problem. While I can’t be certain without running some tests on the computer itself, my best guess is that you are having some issues with your power supply, which if this is a desktop (not a laptop) computer can be easily fixed by replacing it with a new one.
Replacing a power supply can be easily done at your local computer repair shop, for about a hundred dollars.
If you are comfortable working inside your computer, and know how to avoid causing static damage to the circuit boards in the computer, you can purchase a power supply and replace it yourself.
I have included a link to a power supply that I like to use. You want to make sure this is the right size and type for your computer before you purchase it.
