Hi, we have a HP Compaq D530S. When we got back from a week's vacation, it started shutting off unexpectedly. Sometimes the computer can be booted up again immediately, and sometimes it needs to cool. It seems as though it is getting too warm and then it powers off. I have not heard big surges of fan activity since we got home, like I did before we left on vacation. I blew out what little dust there was inside, checked the CPU fan connector with a meter (no open circuits between terminals), and see nothing unusual with the capacitors.
Is it probably the fan that needs to be replaced, or the motherboard, or something else?
Thank you!
Is the cpu fan working if so you may have to remove it and clear any dust or fluff that has collected on the heat sink. sometimes you cannot see the fluff etc until fan removed.
If fan not working replace fan
