My mom’s PC was interrupted with strange and mysterious problems last month. It started with the monitor occasionally black out and switches to standby mode. We suspected the monitor was giving trouble but my husband said we shouldn’t rule out bugs in the CPU.

We took our CPU to the technician to have it checked. To cut a long story short, the CPU booted up normally as well as the monitor everytime it was run at the PC workshop. As soon as we brought the setup home, the monitor would fail to power up or reverts back to stand-by mode sooner or later. We made more than 5 trips to the technicians. None of them were able to diagnose where the source of the problem is.

My husband dismantled everything in the CPU to test every internal parts – CPU chip, ddr memory sticks, graphics card, sound card, network card, hard disks – but no components gave us a clue as to where the problem is.

The only clue, after more than a week of frustation, is the power source. So we moved my mom’s PC to another location in the house temporarily in order to use a different power plug source. The CPU and monitor booted up nicely but to be really sure, we told her to run it a few more days there. She never encountered a single glitch at all within the next couple of days.

I convinced my dad to fix or replace the electricity wires and plugs along the sector where my mom’s PC was located. We moved the PC back to its original location and since that day, my mom’s PC has been running like new.

It is a huge relief for us to finally realize where the source of the problem was. So if you find yourself with strange PC problems that occurs only at home and nowhere else, check the power source too.
