Ur computer gave you a warning in startup that said thermal port trip and then shut dwn what do you do u jst installed a new motherboard there is no dust in the machine the fan ovr the CPU is loose?

Answer 1

If the CPU heatsink is loose or improperly installed, this could certainly cause the problems you are describing. The CPU heatsink/fan assembly should attach firmly on top of the CPU, and with some types of fans this can be very difficult to do. Be careful and patient.

Another thing to think about is this. Most motherboards have a special power jack for the CPU fan, this special jack reports back to the machine with information about the performance of the fan, fan speed in particular. If you have plugged the fan into another port, or if your fan doesnt use that type of port & is plugged in elsewhere, this port will be reporting 0 RPM back to the machine & the machine will shut down as it thinks the CPU fan is not turning. This feature can be turned off in BIOS if needed, but i would not recommend doing so unless you are sure everything else is properly configured.

Please open up the "discussion" link on the left frame of this page & answer a couple questions....

1. Did this system used to work, but stopped at some point? Or is it something you've just put together?

2. What type of motherboard & what CPU are you using?

Sounds to me like something in your computer (most likely the CPU) was overheating and the computer shut itself down to avoid damaging it.

Heres something to try. Unplug the computer and open it up. Use a can of compressed air (available at any electronics or department store) to blow out all the dust from the internal components.

Once this is done, check that the fans inside are able to turn freely, if you feel friction when turning the fan, the fan has gone bad and will need to be replaced.

If this doesnt solve your problem, I recommend you take it to a professional for repair.
