Troubleshoot spontaneous shutdowns

By darksoul ·
I have a user who has a one year old PC. Periodically, the power just spontaneously shuts off. I checked the power connections, and all components, but still have the same problem. The user informed me that if he "whacks" it (AAAARRRRGGGGHHHHH!!!!!), it sometimes will power back up. Budget says, if it's not broke don't fix it, and if a part can be replaced, do that rather than replace the machine.

Out of ideas folks.

Troubleshoot spontaneous shutdowns

by TheChas In reply to Troubleshoot spontaneous ...

My first thought is an intermittent sticking power button / switch.
Mount a replacement switch on the outside of the case for a couple of days to verify if that is the problem.

Next, would be a dirty or weak contact on the power supply connection to the motherboard.
You may need to inspect both the plug and socket under magnification.

Don't forget to try connecting the PC to a different outlet and / or power strip.

I would also double check for any work station setup issues.

Afterthat, I would start using gentle shock with a small rubber or plastic hammer. (the handle of a small screwdriver works well also)
Start with the power supply, and the regulator section of the motherboard.

I year old it should have inbuilt monitoring of the CPU temperature etc. Activate this and have it log the cpu temperature on a regular basis. If the CPU fan is not working properly, or not enough cool air getting into the case; the cpu could be overheating and activating a protective shutdown.

It may also be a power drop on the line he is on causing a brown out, try an Uninteruptable Power Supply to see if it changes the problem or place soemthing on the power line to monitor the power at that point. Too many devices on one electricity circuit can cause power fluctuation drops that will trigger a brown out on the PC

Most likely:
Bad CPU fan / excessive dust.
Bad connection in the Wall Plug. (Call Electrician)
The PC is not plugged into the same line as the Laser Printer . Correct?
