pc keeps rebooting

The pc  boots up and after a short period of time it just shuts down and reboots, the time to shut down varies but seems to be shorter after the pc has been trying to boot up for a while - it even does it with nothing attached to the board eg booting to BIOS it shuts down after a while.

I suspect a fault in the motherboard with replacement the only option

So you have physically removed everything that is non essential from the motherboard (only CPU, RAM, Power Supply) and it is doing this?

I think the Mobo and Power Supply are the most likely suspects. Can you get in the BIOS long enough to montior the temperature and see if it is out of the normal?


I have done that and the temp is well within tolerance and I have also changed the power supply

I have added new ram , video card and power supply still reboots even after resetting bios to default settings
Let us know how it turns out, I'll keep watching the thread.


After all this it turns out it was something to do with the case it seems there was a problem with the power,reset switch, front usb port  circuit board. This particuar case has a small circuit board with the switches and usb ports  on it and I suspect nicotine and/or tar had accumulated on it as the air intake fan was behind the circuitry and the inside of the case and the fans were covered in a brown sticky substance.
The biggest issue with it was that even out of the case it rebooted sometimes with nothing from the case attached but i have since put all the original parts into a new case and it has been running for 48 hours without any problems.
